Humble Math - 100 Days of Place Value, Rounding & Estimation

A good book, easy to follow.

Very useful for 8 year old son

The book is great because it offers a balance of practice and learning. They are freshly printed and satisfying to use.But, there are some inconsistencies in the teachings (image 2 attached) where rounding a single digit to the nearest ten is 10, not zero. This may happen in every practice book so be advised!Other than that, great book! 4/5 and I will purchase again if needed :-)

Great for practice. Really good resource.

I think this book is useful. The problem is pretty straight forward and good for practicing if you already have other core curriculum. I did not expect it to have problems pass 4 digits though.
