I would like to buy a workbook (with basic math for my DS but do not know which one. My DS has Jolly Phonics and he is not interested in these books. In his pre- school year I bought him a workbook from School Zone www.amazon.co.uk/Preschool-Workbook-School-Publishing-Company/dp/0887431453/ref=sr_1_1?s=books&ie=UTF8&qid=1302712353&sr=1-1. He liked to work with it. School Zone sells workbooks in maths on amazon but this is an American publisher so I want something good but English. DS is 5. Many thanks!
