My first number book is great for children who are just starting school. It covers a wide variety of things from patterns to shapes, from taking away to adding up, from ordering and measuring; it even has a great game to play called Hopping frog game! This has helped my younger brother lots especially with big numbers because at the end it has two pages about numbers like one hundred or fifty, and it has a picture of that many things, e.g. 20 - twenty clothes pegs. This book is factual but fun which is very rare so a very well done to Marie Heinst (the author of the book)!
