My light bulb came on!
I can make a cute chip board book with Greta's high-frequency words.
Greta loves girly, frilly, pretty things but she doesn't love sitting down to learn her high-frequency words. So far, so good. She has already studied her words and enjoyed everything in the book.
Here are some pics of the book. I left a couple of pages blank in the back for additional work... maybe math facts.
