Hi, I've seen threads on MN before about these workbooks, particularly being used by home schoolers, so I bought the first Mental Maths book for KS1 on the internet. My DS and I are in the habit of doing one double page spread each night as a way of reinforcing the maths he is taught in his classroom.
He really loves the format of this book and so I just looked on the SandS website to see what else they had and got completely overwhelmed with the different "types" of numeracy. There were number books, mental arithmetic, mental maths, problem solving books, key maths books etc. They all seemed to cover similar areas, so is it how the questions are presented that makes the different kind of workbooks useful, or can I leave one sort and just concentrate on others? Any advice gratefully received as I don't know which direction to go in !
