How to go from an understanding of 1/2 to knowing how to do 3/5 x 10. It’s not hard with Cuisenaire Rods! The trick is to use the word “of” when reading the multiplication symbol. Everything becomes clear!
I learned this from the Miquon math curriculum. It is a WONDERFUL program that uses Cuisenaire Rods to teach concepts and it is extremely inexpensive – totally worth it to try at home with your K-4th grade children! If I could only choose one math program to use with my kids, this would be the one!
