One of the most wonderful gifts you can give a beginning reader is the gift of his or her first 100 words. 
Anyone who can read and write the top 100 words in English has really made strides, because these 100 most common words comprise almost half of all the words we regularly read and write in English!
3 ideas for teaching the top 100 words in English
1. Make a word wall with the top 100 words on it. Organize the words by letter category (a, b, c, and so on) for easier reference. Help the child consult the wall for spelling help when writing little books, or letters to grandparents, or signs, etc.
2. Make predictable books together, that incorporate the words. The child can draw pictures and write the particular word you are trying to teach, and you can write the other words. For example, a predictable “all” breakfast book might read: I ate all my cereal. I ate all my eggs. I ate all my toast. I ate all my muffins. I am all done!
3. Make word cards and use them as prompts. For example, if you pulled the by card, you could make a quick verbal game of naming all the things that are by other things in the house. After the verbal game, on a large sheet of paper, the child could draw pictures of some of the things that are by each other and label the whole picture as “My By Map.”
