Giving children reading material on topics that they are interested in can keep them interested and focused. Comics are a great idea, but if you want to stick to educational content, try an interesting book involving the child's favorite animal, sport or other topic of interest. You may want to ask them to read aloud from periodically, not necessarily in front of class but one on one while other students are taking their opportunity to read silent. That way you can evaluate their reading and answer any questions they have about any words they may be stumbling on.
Children with dyslexia are likely to reverse the consonants in any word especially if it is new. They may also have a few words they write regularly, but misspell while doing their class work or home work. Go through each child’s assignments briefly and pick out words that may be misspelled on a consistent basis and have the child rewrite the set a words a set amount of times. Regularly evaluate their work to pick out new sets of words monthly so that the child may practice writing them correctly until they are ready to move on to a new set of words.
