My audience was a nephew who is currently in the 4th grade. Overall he found the book to be visually appealing and easy to follow. The math involved in the book seemed to be below his level of math comprehension as he was able to correctly and quickly see the patterns of the shapes and was able to come up with various way to find the correct answer. The patterns became easily visible to him, but only after one or two examples were done, from there on out he breezed through it. The rhymes placed a smile upon his face and I was asked to read the book one more time. Perhaps this book was a little above him, but for the target school year group of 1-4, its not at all bad to aid children in conceptualizing a typical problem in a different manner to ease solution finding.
