## Lesson: Multiplication Facts for 2, 5, and 10

Introducing the Concept

It is a good idea to begin by spending some time making connections between addition and the new operation of multiplication. This will allow you to tie what the children have learned to what they are learning in this chapter.

**Materials:** adding-machine paper and markers in 3 different colors for demonstration; paper and pencil for each child

**Preparation:** Make a large number line on the adding machine paper from 0 to 100.

**Prerequisite Skills and Concepts:** Children should know basic addition and subtraction facts and be able to find sums to 100.

Display the large number line on the chalkboard or bulletin board.
