For Kindergarten we used a Horizons Math K book and a Hands-On Standards book with manipulatives (links below). Sierra is currently starting with both those books and I’m about to buy the first grade levels.
Hands-On Standards preK-K was the first math book I bought for Brooklyn. I also bought a bunch of manipulatives.
I keep all the math stuff in this cute ottoman in the school room. ($20 ottoman at WalMart)
Manipulatives are the funnest thing ever. Both girls could play with manipulatives all day.
I bought all those manipulatives (and the Hands-On Standards book) at a teacher store in Texas. It was probably $100 for everything but worth every single penny.
This site sells everything together.
(I haven’t personally ordered from that site, but it’s rated ‘A’ on the BBB)
The other thing we use for math is Horizons Math. This is a workbook approach to math.
You can buy manipulatives and use them with the book if you want to (which obviously I do!). I don’t think the teacher’s manual has any information for adding manipulatives, though, so you’d have to just figure that out yourself.
And on that subject, I didn’t buy the teacher’s manual but I’ve heard it isn’t helpful at all.
The pages are colorful and fun. Brooklyn really loved this book.
