Part 1

Mr. Carter took out 6 boxes of crayons from his cupboard. There were 7 crayons in each box. How many crayons were there?

What is an addition equation for this problem?

$7+7+7+7+7+7=42$

This means 6 groups of 7 is 42.

What is a multiplication equation for this problem?

$6\times7=42$

Part 2

Let's practice.

Write a multiplication equation to show each situation.

a) 7 people show how many fingers are on their right hand (each student has 5 fingers only on their right hand).

$7\times5=?$ (You find the solution!)

b) How many wheels on 6 bicycles?

$6\times2=?$ (You find the solution!)
