Saxon phonics has a daily spelling sound test where they want your child to be able to write all the letters and diagraphs etc. that make the same sound such as; a, ai, ay, a-e.  Well my son got real bored of this, so what I do instead is every other day I lay the flashcards out and tell him to pick all the ones that make the /a/ sound and so on. 

There are also sight word cards which I lay out and put tokens, or m&m’s what ever you can think of and if he reads it he gets to take the token.  He actually begs me to do this with him all the time now.  You just have to think of how to make learning fun.  It isn’t easy at first.
