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

Developing the Concept

Once children feel comfortable skip counting by twos, fives, and tens, introduce the new operation of multiplication and its relationship to skip counting. You may wish to use the lists of twos, fives, and tens as developed from the number line. Encourage children to share their thoughts and strategies as the lesson progresses.

**Materials:** countable objects (such as bottle caps or paper clips) to be placed on an overhead projector for all to see; 10 index cards per child; paper and pencil for each child

**Preparation:** none

**Prerequisite Skills and Concepts:** Children should know how to skip count by twos, fives, and tens.

**Wrap-Up and Assessment Hints**

Children need a lot of practice with multiplication. Remind them that it took time to learn the addition and subtraction facts. Have them remember how they learned those facts and apply their understanding to the multiplication facts. Encourage the use of flash cards daily. As you assess each child, check if he or she has a clear understanding of the meaning of multiplication through repeated addition, skip counting, and arrays.
