We just got the first grade Singapore Maths book for our Ker. I'm 100% sure he knows 95% of the content, but we want to make sure he knows it in the right way for school!
Kriston -- I wish I'd seen this post before I bought them last night; I was remembering that you used Singapore math! I bought the text and the workbook, but I guess I should have gone for the homeschool book. Maybe for 1B. :-) However, you can't really beat the price, can you? I'll have to check out the books once they arrive ...
