Review: Excellent practice - Great workbook to practice their math and either use it for homeschool or practice from their regular school. Excellent problems covers all the areas.
Review: I’d buy it again - Perfect tool. I wish it had a bit of color or maybe a break for a math game in the endless pages of math, but as a tool, it’s just what I needed. Kids take about 15 minutes each day working on easy math, and they get a really solid, focused foundation by the end.

Kiddo wanted to practice math outside of school and this book is great! Only has a handful of problems per page with a couple word problems. He has no complaints. He just turned 8.
