Here’s a quick free math tutoring video of my daughter making 3,000 with our Base Ten Blocks and Cuisenaire Rods. We only have 9 blue hundreds so she had to make another hundred, and, in the process, discovered that 4(1+3+5+7+9) = 100! I’m sorry I didn’t leave the camcorder on for our discussion about that afterward! Lots of neat things to discover when you use Cuisenaire Rods!
