When I first researched homeschooling products and resources, I spent quite some time looking at different math manipulatives. For one thing, there are so many, and for another, I love math. I remember wondering whether these colored rods would really be worth purchasing, as they are on the expensive side. And my math education, as far as I could remember, had been accomplished without a single manipulative.
Then I found Miquon Math, and immediately liked the concept.
