    Lesson 11 of 48: Sensory Perception Training: Visual, Auditory, and Spatial Foundations for Literacy and Numeracy

    Every Tuesday, we open up one lesson of the Dyslexia Trainer Certification Program here on the blog, all 48 of them, one week at a time. Whether you are a teacher, a parent, or an education professional, this series shows you exactly what certified dyslexia trainers learn, and how the program works from the inside.

    This week: Sensory Perception Training. Visual, Auditory, and Spatial Foundations for Literacy and Numeracy

    Reading, writing, and arithmetic depend on a network of sensory processes working together. When one of them is underdeveloped, the brain compensates, and that shows up as slow processing, fatigue, and avoidable errors. Function training strengthens recognition, memory, and sequencing in the visual, auditory, and spatial domains, preparing the brain to handle academic tasks more efficiently. This lesson covers every function area with practical examples and selection guidance.

    Lesson 11 in about 90 seconds. Watch more on our YouTube channel American Dyslexia Association.

    What this lesson is about

    Function training does not replace instruction in reading, writing, spelling, or math; it prepares the brain to handle those tasks more efficiently. As functions improve, students more readily recognize symbols, maintain order in words and numbers, follow instructions, and integrate information across senses. This lesson outlines each function area, shows how to implement function training for school-age learners (and why we limit preschool to F only), and gives practical examples and selection guidance for trainers.

  • Inside the AFS-Test, Week 7 of 25: Visual Recognition

    Inside the AFS-Test, Week 7 of 25: Visual Recognition

    Every Wednesday, we take you inside the AFS-Test, the standardized assessment that allows Certified Dyslexia Trainers to definitively diagnose and categorize dyslexia and dyscalculia. This is week 7 of 25.

    This week: Visual Recognition

    Visual recognition is the ability to spot the essential detail and tell similar shapes apart: b and d, ie and ei, 6 and 9. A child with underdeveloped visual recognition sees perfectly well, but sorting what they see takes longer and costs more effort. In the standardized AFS-Test, the child works through playful exercises that show precisely how reliably they differentiate optical patterns. If this area needs support, targeted training strengthens it step by step, before letters are even involved.

    About the AFS-Test

    The standardized Attention-Function-Symptom Test has been used worldwide for more than 25 years. It examines the attention span, the sensory perceptions, and the error symptoms of a child, and turns the results into an individualized training plan following the AFS-Method.

  • Lesson 10 of 48: Attention Training: Building Focus for Learning Success

    Lesson 10 of 48: Attention Training: Building Focus for Learning Success

    Every Tuesday, we open up one lesson of the Dyslexia Trainer Certification Program here on the blog, all 48 of them, one week at a time. Whether you are a teacher, a parent, or an education professional, this series shows you exactly what certified dyslexia trainers learn, and how the program works from the inside.

    This week: Attention Training. Building Focus for Learning Success

    Attention is the foundation of all learning, and for dyslexic and dyscalculic learners, staying focused on letters and numbers is especially hard. This lesson explains what attention training is, how attention differs from concentration, and why situational inattentiveness around symbols is not the same as ADHD. It closes with a practical toolkit, including kinesiology-based exercises, to help learners reach and hold optimal focus.

    Lesson 10 in about 90 seconds. Watch more on our YouTube channel American Dyslexia Association.

    What this lesson is about

    Attention is a vital foundation for all learning. Without it, even the most carefully designed training cannot be fully effective. For learners with dyslexia or dyscalculia, maintaining attention on symbol-based tasks, such as reading, spelling, writing, or math, can be especially challenging. Attention training in the AFS Method addresses this challenge directly, using structured exercises to prepare the brain for focused work.

    Attention Training. Building Focus for Learning Success, illustration from Lesson 10

    Attention training refers to structured, targeted exercises designed to help learners focus their thoughts and sustain concentration on a specific task over a period of time. In the AFS Method, attention training is one of the three core pillars, alongside function training and symptom training, because it addresses a key barrier to learning for many individuals with dyslexia and dyscalculia: the difficulty of maintaining mental focus on written symbols and numbers.

    Attention Training. Building Focus for Learning Success, illustration from Lesson 10

    What you will learn in Lesson 10

    • What attention training is, and how attention differs from concentration
    • Why dyslexic learners lose focus around letters and numbers
    • Situational inattentiveness vs. ADHD
    • A practical toolkit, including kinesiology-based exercises

  • Inside the AFS-Test, Week 6 of 25: The Sensory Foundations

    Inside the AFS-Test, Week 6 of 25: The Sensory Foundations

    Every Wednesday, we take you inside the AFS-Test, the standardized assessment that allows Certified Dyslexia Trainers to definitively diagnose and categorize dyslexia and dyscalculia. This is week 6 of 25.

    This week: The Sensory Foundations

    Reading, writing, and arithmetic rest on a network of sensory perceptions working together: seeing precisely, hearing precisely, and knowing where you are in space. When one of these functions is differently developed, the brain compensates, and that costs energy, speed, and accuracy. The standardized AFS-Test checks eight function areas, from visual recognition to body perception, to definitively diagnose and categorize where support is needed. Over the next eight weeks, we will look at each one of them: what it does, how the test checks it, and what training looks like when it needs strengthening.

  • Free Dyslexia Resources for Parents and Teachers: What We Give Away on International Literacy Day

    Free Dyslexia Resources for Parents and Teachers: What We Give Away on International Literacy Day

    Free dyslexia resources from the American Dyslexia Association, all in one place: 1,500 printable worksheets, two worksheet generators, a word and a picture every day, ten math games in one app, and a learning platform for families. None of it costs money. Most of it needs no sign-up. We are publishing this list on International Literacy Day, which turns 60 today, because the day is about access, and access starts with price.

    Why free, and why today

    At least 739 million young people and adults still lack basic literacy skills, and 4 in 10 children do not reach the minimum level in reading. Those are UNESCO’s figures for International Literacy Day 2026, the sixtieth since UNESCO proclaimed the day in 1966. Nobody fixes that from Osprey, Florida. What a small association can do is remove the first barrier: no family and no teacher should have to pay to start. A child with dyslexia or dyscalculia does not need a miracle. The child needs practice that fits how he or she perceives letters and numbers, in small daily doses, from adults who stay calm. The free dyslexia resources below are built for that.

    More on this topic: all of this stays free because the American Dyslexia Association is a nonprofit and a 501(c)(3) public charity. Read what ADA’s 501(c)(3) dyslexia charity status means for donors and members.

    1,500 free worksheets, no sign-up

    Our largest collection is the set of 1,500 free printable worksheets on this blog. They follow the three parts of the AFS-Method: attention, sensory perception (the “function” part), and symptom training in reading, writing, and math. Pick what fits your child, print it, use it at home or in class.

    One rule before you print anything: do not start with the mistakes. A child who reverses letters or loses the line does not need the same exercise ten more times. The child needs a few minutes of perception training first, then one short reading or writing task. The worksheet post explains why practicing the errors alone does not work.

    Every freebie on dyslexia.me is licensed under Creative Commons, so teachers may copy and share them. The Freebies section has the running list, and the association keeps its own free worksheet library on the ADA website.

    Two worksheet generators

    Two generators on this blog turn one word or a word list into practice sheets in seconds. The Handwriting Worksheet Wizard lets you choose print or cursive, the font size, and the line pattern. The Math Worksheet Wizard lets you choose the operations and the level, then prints arithmetic sheets for elementary school. Both are free for teachers and for parents who teach at home.

    Something small every day

    Short daily practice beats one long session on the weekend, so two of our sites publish something new every day.

    Word of the Day takes one English word a day through the three steps our trainers use: word image, word sound, word meaning. This is the AFS-Method procedure called word formulation, and it belongs to the symptom part of the method, the part that trains reading, writing, and spelling directly. A word only stays in long-term memory when a child has seen its shape, heard it clearly, and understood what it means, which is why none of the three steps can be skipped. Read it together, say it, write it, and you have done ten minutes of word formulation without opening a workbook.

    How the three steps work in detail, with all 1,612 free words, is explained in Dyslexia Spelling: How Word Formulation Teaches a Word Through Image, Sound, and Meaning.

    Picture of the Day shows a new spot-the-differences picture every day. Your child solves it online, or you print it as a PDF with or without the solution. It looks like a game, and it is one, but it trains visual recognition: the child has to look closely, compare two pictures, and notice where they differ. In the AFS-Method that is the function part of the training, visual recognition, and it is the same skill a child needs to tell b from d or to see that a word on the page is not the one they just read. If you prefer paper, there is a printable set of 10-differences puzzles on this blog.

    Ten math games in one free app, with no ads

    Free apps for children usually pay for themselves with advertising. A University of Michigan study of 135 apps for young children found ads in 95 percent of them, and in every single free app (Meyer et al., Journal of Developmental and Behavioral Pediatrics, 2019). AFS5 is the exception we built: ten math games in one app, from addition and subtraction to fractions, counting money, and telling time. Ten languages, no account, no ads, no subscription. It runs on iPhone, Mac, and Android.

    A learning platform for families: parents.learnedy.com

    parents.learnedy.com is our online learning platform for parents. The parents package is free: access for up to four children, quizzes without limits, and exercise books you put together for your own child. It has been free of charge and free of advertising since March 2020, and the site promises to ask its users before that ever changes. The platform is endorsed by the American Dyslexia Association and by the International Federation of Dyslexia and Dyscalculia Associations.

    How much practice does a child with dyslexia need?

    Ten to fifteen minutes a day at home, plus one session a week with a trained specialist. That is the pattern the AFS-Method has used since 1997, now in more than 60 countries, and it is the pattern behind the numbers: in a long-term study of children trained this way, 85 percent improved significantly (Kopp-Duller and Pailer-Duller, Dyslexia – Dyscalculia!?, 3rd edition, 2020). Every home session follows the same order: a minute or two of attention, a few minutes of perception exercises, then one reading, writing, or math task. Stop while the child is still willing. Praise every small step, because, in the words of the method’s author, praise is the daily bread of these children. If you want to see how trainers plan this, Lesson 9 of our free 48-part series turns a training plan into home practice.

    Which of the three areas a child needs most is not something you have to guess. The AFS-Test is the educational test built for that question: it looks at the attention span, the sensory perceptions, and the errors the child actually makes, and it has been evaluated on more than 100,000 children between 6 and 14. Dyslexiatest.com explains what the test covers and lists the certified trainers who conduct it.

    Questions parents ask us

    How much should a child with dyslexia practice each day?

    Ten to fifteen minutes a day at home, every day, plus one session a week with a Certified Dyslexia Trainer. Short and daily works better than long and rare. This is the home-training pattern of the AFS-Method (Kopp-Duller 2021). In the long-term study of children trained this way, 85 percent improved significantly (Kopp-Duller and Pailer-Duller 2020).

    Are free worksheets enough to help a child with dyslexia?

    No. Worksheets that only repeat the errors do not help a child with dyslexia and can make things worse. The AFS-Method trains three areas in every session: attention, sensory perception, and only then the symptom, meaning the actual reading, writing, or math task. Use worksheets as the last step of a short session, not as the whole session.

    From what age can a child use these free dyslexia resources?

    The perception exercises, the picture puzzles, and the counting games work from preschool age. The AFS-Test, which tells you which areas to train, has been evaluated on more than 100,000 children aged 6 to 14. If you suspect a problem before school, start with perception games and have the child assessed once reading instruction begins.

    What if the problem is math, not reading?

    The International Dyslexia Association describes dyscalculia as a mathematical disability in which a person has unusual difficulty solving arithmetic problems and grasping math concepts. An estimated 4 to 7 percent of students have it, one or two per classroom, and it often goes together with dyslexia. The same three-part training applies. For arithmetic, always pair the written number with a quantity the child can touch or count. Pictures on a page are not enough: use coins, blocks, or beans, because counting real things is the base of all arithmetic.

    For teachers who want to go further

    If you teach and want to work this way professionally, the Dyslexia Trainer Certification Program is accredited by the American Dyslexia Association. Lesson 1 is free. In September the program site marks International Literacy Month with half-price enrollment for the first 50 sign-ups, through September 30.

    Read to them tonight

    International Literacy Day is a good excuse for the simplest thing that works: read aloud to your child, even if the child can read alone, and especially if reading is hard. If you need a text to start with, bestselling author Don Bentley wrote a message to children with dyslexia for us last month. It is short, and it is worth reading out loud.

  • Lesson 9 of 48: From Session Design to Home Practice: Using the Training Plan Effectively

    Lesson 9 of 48: From Session Design to Home Practice: Using the Training Plan Effectively

    Every Tuesday, we open up one lesson of the Dyslexia Trainer Certification Program here on the blog, all 48 of them, one week at a time. Whether you are a teacher, a parent, or an education professional, this series shows you exactly what certified dyslexia trainers learn, and how the program works from the inside.

    This week: From Session Design to Home Practice. Using the Training Plan Effectively

    A good training plan is a roadmap: it makes sure every session addresses attention, sensory function, and symptoms, while staying flexible for what the child needs on that particular day. This lesson covers session design, documentation, and progress monitoring, and shows how a plan generated from AFS-Test results guides the work from the most significant needs toward systematic improvement.

    Lesson 9 in about 90 seconds. Watch more on our YouTube channel American Dyslexia Association.

    What this lesson is about

    Effective training for learners with dyslexia or dyscalculia requires a structured yet flexible approach. Each session should address attention, sensory function, and symptoms, but the order and emphasis can vary depending on the child’s needs on that day.

    Documentation is an essential part of the process, allowing trainers to monitor progress, adjust plans, and ensure that all areas are addressed over time. The training plan, whether written up manually or generated via the AFS Test, serves as a roadmap to guide the process, ensuring that interventions target the most significant needs first and build systematically toward improvement.

    A training session should always include three components, attention training, function training, and symptom training, though the sequence does not need to be followed rigidly. Each session should begin with an activity that helps the child focus, but it may be necessary to return to an attention exercise later if focus is lost during other parts of the session.

    What you will learn in Lesson 9

    • How to structure a training session across attention, function, and symptoms
    • Flexible emphasis: reading what the child needs on a given day
    • Documentation that makes progress visible
    • Using AFS-Test-generated training plans as your roadmap

    Every Wednesday, we take you inside the AFS-Test, the standardized assessment that allows Certified Dyslexia Trainers to definitively diagnose and categorize dyslexia and dyscalculia. This is week 5 of 25.

    This week: The Attention Test

    Attention is where every reading or math task begins. The AFS-Test measures how well a child can focus their thoughts on symbols: letters, numbers, and words. Many dyslexic children are perfectly attentive when playing or building, but drift the moment symbols appear. This situational inattentiveness is not ADHD, and telling the two apart matters, because each calls for completely different support. The attention section of the standardized AFS-Test makes this measurable, in playful parts a child can complete without fear.

  • Lesson 8 of 48: From Understanding to Action: Roles and Strategies in the AFS-Method

    Lesson 8 of 48: From Understanding to Action: Roles and Strategies in the AFS-Method

    Every Tuesday, we open up one lesson of the Dyslexia Trainer Certification Program here on the blog, all 48 of them, one week at a time. Whether you are a teacher, a parent, or an education professional, this series shows you exactly what certified dyslexia trainers learn, and how the program works from the inside.

    This week: From Understanding to Action. Roles and Strategies in the AFS-Method

    Real progress happens when the child, parents, teachers, and specialists pull in the same direction. This lesson examines the unique contribution each person brings, and how the three components of the AFS-Method, attention training, function training, and symptom training, work together in practice. It also shows what happens when collaboration fails, and how trainers keep everyone motivated and aligned.

    Lesson 8 in about 90 seconds. Watch more on our YouTube channel American Dyslexia Association.

    What this lesson is about

    Supporting a child with dyslexia or dyscalculia requires more than isolated interventions, it demands a coordinated effort from everyone involved in the child’s learning journey. The AFS Method emphasizes that genuine progress is achieved when the child, parents, teachers, and specialists work together toward shared goals. In this lesson, we examine the unique contributions each person brings to the process, as well as the importance of building understanding, fostering motivation, and maintaining consistent communication. We also explore how the three components of the AFS Method, attention training, function training, and symptom training, form a comprehensive framework for effective, individualized support. Forging Understanding: Child, Parents, Teacher, Specialist It is crucial that a child with dyslexia or dyscalculia is met with understanding in their environment regarding their unique challenges. This understanding should primarily come from parents but also from teachers. The collaboration between parents, teachers, and specialists is essential. While understanding is a prerequisite, targeted support is an absolute necessity. However, effective support can only be successful if the child, parents, teachers, and specialists work closely together and complement each other.

    From Understanding to Action. Roles and Strategies in the AFS-Method, illustration from Lesson 8

    If this collaboration is successful, the child will eventually experience progress, which can be observed as improvements in learning. However, if collaboration is lacking or ineffective, the child may develop psychosomatic symptoms or even significant mental health issues over time, and training success will be significantly delayed.

    From Understanding to Action. Roles and Strategies in the AFS-Method, illustration from Lesson 8

    If secondary issues have already developed, additional professionals such as medical doctors, psychologists, or psychotherapists should be consulted. However, this should always be decided on a case-by-case basis, depending on the severity of the developed secondary dyslexia or dyscalculia. Each of the involved individuals plays a specific role in ensuring successful training: The Child Once a test or assessment has confirmed the diagnosis of dyslexia or dyscalculia, it is helpful to have an age-appropriate discussion with the child about their struggles. Many children feel a sense of relief upon receiving an explanation, as well as an interest in learning more about it. Often, for the first time, they realize that they are not simply lazy, difficult, or unintelligent.

    What you will learn in Lesson 8

    • The roles of child, parents, teachers, and specialists
    • How attention, function, and symptom training work together
    • Building motivation and consistent communication
    • What happens when collaboration fails, and how to prevent it

    Inside the AFS-Test, Week 4 of 25: Why Screenings Are Not Enough

    Every Wednesday, we take you inside the AFS-Test, the standardized assessment that allows Certified Dyslexia Trainers to definitively diagnose and categorize dyslexia and dyscalculia. This is week 4 of 25.

    This week: Why Screenings Are Not Enough

    A child can score average on a screening and still struggle every single day. Screenings, reading tests, IQ tests, and phonological assessments each look through one small window, and none of them alone can definitively diagnose and categorize dyslexia. The AFS-Test takes the comprehensive route: it examines the attention span, eight areas of sensory perception, and the concrete error symptoms a child shows when reading, spelling, or calculating. Only when all three areas are tested together does the full picture appear, and with it the right kind of help.
