Mathematical Reasoning™ books are easy to follow and allow kids to jump around... My sons teacher loved it, as well, saying the math concepts are age appropriate for him.

We use The Critical Thinking Co. products as part of our homeschool curriculum. The Mathematical Reasoning™ Level A book has been a wonderful tool. The instructions are easy enough for my kindergartner to read. My son loves math now!
