### LESSON PLANS AND RESOURCES FOR TEACHING MULTIPLY TENS, HUNDREDS, AND THOUSANDS!

Teaching How to Multiply Tens, Hundreds, and Thousands can be a lot of FUN!

Since 4th graders know how to multiply by 1 and multiply by 10, today's lesson is mostly a tip and a shortcut since your students already understand the "why" of the math skill.

The Essential Question is How Does Understanding Place Value Help You Multiply Tens, Hundreds, and Thousands? By now your students have studied the shortcuts for multiplying any number by 10, 100, or 1,000, but still understand the "why?" and the "how?" it all works. Today's lesson is about

shortcuts.

Introduction to How Multiply Tens, Hundreds, and Thousands

1. Review a few basic multiplication problems, on the board, or on your students' white boards.

3 x 1 = 3

3 x 10 = 30

3 x 100 = 300

12 x 1 = 12

12 x 10 = 120

12 x 100 = 1,200

To multiply any number by 10, just add ONE zero on the end.

To multiply any number by 100, just add TWO zeros on the end.

To multiply any number by 1,000, just add THREE zeros on the end.

The important part of this tip is to make sure your students are placing the exact number of zeros that are needed.

To review and check for understanding, use this example.

10 x 1 = 10

10 x 10 = 100

10 x 100 = 1,000

Discuss that the MAIN number you are multiplying by is 10, which already has a zero, then add on the EXTRA number of zeros from there.

2. Moving to other numbers, for example, 2, 20, 200...

What is 20 × 8?

Imagine the problem without the zero. Then it just becomes 2 × 8 = 16. Then, just add a zero to the 16, for 20 x 8=  so now the answer is 160. 200 x 8 = 1,600.

3. Why does the shortcut work?

It works because you can multiply in any order.

When multiplying by 40, we can change the 40 into 4 x 10 =.

Example:

40 × 11 = 10 × 4 × 11

First multiply 4 × 11 = 44. Then, multiply by 10 × 44, getting 440 as your answer.

OR, for a "no winner" version, the goal is for the students to solve the cards independently, but to completely cover the board together. This version can ALSO be played two ways. One way is with the answer page as the game board, another way is with the math problem page as the game board instead.
• You can also play this game with cutting all the cards and matching up the problems with the solutions.
• For movement, place the problem cards around the room and the student(s) have to solve the math problem and leave the correct answer card at that location. Have a second student check the answers to extend the game.
• Mix all the cards together, with two students, deal 5 cards to each student and then place the remaining cards face down. Use as a Go Fish card game!
• Lay all the cards upside down on the floor and use as a Concentration (some call it Memory) Game!
