Daughter's favorite
Still a top favorite for our 7 year old. She loves earning her stars as she learns to trace letters and numbers. Coloring and the sounds are engaging and are on target for her age group and being Pre K.

This was a really fun way to get my kids to practice their math. I usually struggle to get them into it and Kids Academy makes it easy.
