Review: One of our favorite workbooks - This has increased my grandson‘s understanding of place value. There is so much variety and how the problems are presented. It has had a great carryover to double checking addition and subtraction with large numbers. He now rounds the problem to check if his answer is likely. This book has made rounding be not a big deal.
Review: Highly recommend! - Great book! Great directions, simplified. But at the same time it goes really in-depth and rounding up to millions and down to hundredths. Definitely a great book.
