Bloomsbury 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...

Its a grr8 book for addition and subtraction math practice suitable for children of class 1 age group 5.5 to 6.5 yrs
