My kid hasn't started on these yet but she will soon! I am so impressed with the thoughtful layout. My hunch is that my daughter won't even know she's doing math. The illustrations captivate a certain audience so well.
This came at just the right time! It has been a great guide to understand multiplication and practice. My daughters love how cute it is and both of them are really getting the concepts (so am I! I came from a memorize all the multiplication tables background and I have found the tricks so useful, too!) I never have a fight about math now!
Once again Kelli has done a great job. Buy this now!
