This is the math program that we shifted to, mid-year. Why? Because it was based on comic books. While my son did enjoy the comics, the math was super-conceptual at times and the explanations were beyond wordy. The last thing my son needs is more words in his happy little world of numbers. It also did not have any natural review and not much repetitive practice. I get that it was trying to get kids to understand the concepts so that they can think their way out of any math problem, but the issue arises when trying to drop that understanding into a child’s brain. Like I said, there was a lot of explanation and sometimes questions that went beyond advanced. I wanted to like this series, but I think it would only appeal to a small percentage of little mathematicians. We are once again moving on for next year.
