Primary Mathematics 1B SET--Textbook and Workbook (Common Core Edition) Paperback – January 1, 2016

Terrible math program. It’s just like common core. It moves to the next topic way too quickly. Adding a few days, then subtracting, then multiplying, etc. How are kids suppose to retain stuff this way? Not for us.

Very Good books to train kids maths.

Fun pictures with proper explanation. Will buy again.
