While I was at the Christian Home Educators of Colorado conference, two different families stopped by my vendor booth to tell me that they were using Two Plus Two Is Not Five. I asked, and both were willing to write something for me about how they felt about the workbook. Here are the two testimonials.

We purchased 2+2 Is Not Five and have found it to be incredibly valuable to us. It gave us helpful tools to teach our children how to calculate math problems in their heads. Justin and Carla Neal (CHEC)

After having used one of the more popular math courses, I needed a bridge to allow my child to master his math facts. 2+2 Is Not Five was the bridge I needed. Thank you so much! Anna, Homeschool mom of four boys. (CHEC)
