Let's do Addition and Subtraction 5-6

Very good set of math problems, slowly progressing towards more difficult. However half way through the book and there are silly ( unforgivable!) mistakes, like it says there 8 cars but 9 is in the picture or the problem is about birds and the question is how many bricks😬For a 5 years old, who is making a big effort to read and understand, it is very confusing....What a shame though as it could have been a good book...

I bought this for my grandson, being schooled at home during the crisis. He enjoys the challenges and rewards. Has more variety in the exercises than many other books of the type. Good value and supports his learning.
