This is a smartboard file which uses the program Notebook. It demonstrates how multiplication is repeated addition. One bicycle with 2 wheels is 1 + 1 or 1 group of 2. Two bicycles with 2 wheels each is 2 + 2 or 2 groups of 2. There are 14 slides and each slide has pictures and number sentences to explain the concept of multiplication. Once the students begin to understand the concept there are interactive slides with just the multiplication sentences with sliding answers.
