Show sky, grass or ground.
Your child may have trouble making her letters the correct size. For example, she may write dOgS instead of dogs.
This activity uses hand positions to help your child understand letter size. Start off with the word boy to practice. For tall letters like b, your child points her thumb up to the sky. For small letters like o, she makes a fist to indicate grass. And for descending letters like y, she points her thumb down for ground.
If you want to do this on a bigger scale, you can also try word-building charades.
