Draw a big truck, shirt or bowl on the board. Then write letter/numbers/etc to make the truck/shirt "dirty" or the bowl "full". Then your child needs to "clean" the truck/shirt or "eat" the soup by erasing (aka washing & eating) the letters/numbers after you say them. If he doesn't know his letters or numbers yet, get the flashcards, say the letter/number and have him find the matching letter/number to erase.
If he doesn't know many letters just write the letters he knows multiple times....
My hope is that this blog will be helpful to someone who wants to teach their child to read (or letters, colors, shapes, numbers or math). If you find any mistakes or items that aren't clear, please let me know. I would love the feedback!
I have everything filed in an easy manner (hopefully) for searching. Here are the different items I have.
