Early-Reader Reviews

“The games are easy to put into practice (even for a mom of 4 with 2 toddlers) and something my daughter would participate in willingly or even enjoy (which is saying a lot for a teen who doesn’t always appreciate a challenge). Clever, helpful, and creative in ways I’d never come up with.”
—Casey Baldwin, homeschooling parent
“The directions are clear, it is easy for parents to pick up and use, yet it gets to the heart of mathematical thinking in a fun, engaging way.”
—Casey Maupin, homeschooling parent
“I love everything about this book – seriously! I feel challenged and encouraged to improve my teaching methods, as well as my own understanding of math concepts. If I could go back in time, I would play a lot more games and spend a lot more time on the understanding and why behind math than on workbooks.”
—Carla Roesler, homeschooling parent
