I recommend this series all the time.
These workbooks are so much better than an online game. So glad I invested in this product! We will be doing all of them. They are self checking( easy on parents), and multi dimensional because they use geography/map skills to answer the questions. They also get progressively harder and that kept it interesting day after day.

Best math workbooks for young students
This entire series of math workbooks are phenomenal. They are a more expensive than other books of similar length but keep kids interested and learning. My son is in second grade and has flown through these books, Graph Grapplers is his fav as there is a joke at the end of each page. Please publish additional titles.

Needs more explanation
It was confusing ordering this product. The computations were the right level of difficulty for my eight year old granddaughter but how to utilize the results was confusing to her and was not sufficiently described. It appears that all the books are similar in how to place the results with several approaches in each book. Again this was not made clear.
