This work is wonderful for teaching children about building numbers from 10 to 99 through a hands-on activity.
It is a set of 10 pages of matching cards.
Accompanying this work with base ten blocks or Montessori golden beads is really beneficial.
My suggestion is to use this work for two different lessons:
1. Have the student match the correct cards with numbers and picture.
2. Give the student the number cards (a few at a time) and have the student build the correct number using base ten blocks or Montessori golden beads.
I hope you enjoy this work and find it to be a wonderful addition to your math shelves.
