Singapore Primary Mathematics Level 5 KIT + Answer Booklet (US Edition)--Textbooks 5A and 5B, Workbooks 5A and 5B and Answer Key Booklet

My kids love using this and it's worth every penny.They work on it at home and love the different math methods.Mastery made easy.

This product is only okay. In the 5A textbook, they make a block out of 200 squares, but they say it has 200,000!I barely recommend this product for anyone.
