In my last Little Hands-on 123s post, I talked about using Duplos to make Montessori number rods.
The traditional rods can be used to introduce addition facts to ten. The Duplo version can be used for addition facts up to your longest rod. The longest rod in the photo is five, but hopefully you have more Duplos or Legos than we do and can go all the way up to ten!
Another use of the number rods is to teach one less than and one more than, as well as two less than and two more than.Choose a rod, lets say the 4 rod and show it to your child, asking her to name the rod. Then ask her to find a rod that is one less than the rod you are holding. Once she can do one more and one less with ease, for any number rod you choose, begin to ask for a rod that is two less than or two more than.
