Your students with dyslexia will benefit from these quick number visual discrimination exercises. These 4 exercises develop number matching and tracking skills by focusing on common number problem areas. Begin with providing students the first worksheet and work your way through to the last one. Each new worksheet is increasingly difficult. Print them off on cardstock and put them in document sleeves to make them reusable for dry erase markers. The last worksheet is an assessment to determine if your intervention was successful. This is a revised edition (updated March 2016).
