Review: Maths guide - A great book for a child who loves maths Review: Excellent - This is a great workbook. It's very well layed out and clear to read. We did a couple of page of each topic each day when school were closed and it worked very well. My child enjoyed it so much so he'd often do two pages of each topic. We will continue to use this book and I Highly recommend it. ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #175,715 in Books ( See Top 100 in Books ) #92 in Children's Books on Arithmetic #239 in Study & Revision Guides for Children #3,372 in Children's Games, Toys & Activities (Books) | | Customer Reviews | 4.7 out of 5 stars 2,260 Reviews | ## Images ![Humble Math - Double Digit Addition & Subtraction: 100 Days of Practice Problems: Ages 6-9, Reproducible Math Drills, Word Problems, KS1, Grades 1-3, Add and Subtract Large Numbers - Image 1](https://m.media-amazon.com/images/I/61ba27CgUJL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Maths guide *by B***A on 16 October 2025* A great book for a child who loves maths ### ⭐⭐⭐⭐⭐ Excellent *by C***E on 20 March 2021* This is a great workbook.
