Warm Up Find the answers to the problems below: What do you notice? 7,000 ÷ 10 = 7,000 ÷ 100 = 7,000 ÷ 1,000 = 36 x 10 = 36 x 100 = 36 x 1,000 = What do you notice?

The Power of a 10 Alignment Lesson

Using only 10’s, can you write a multiplication problem to get a product of 100? Using calculators, complete the Evaluate column of Day 22 “Exploring Power of 10” Identify any patterns you see when you multiply 10 times another 10 or 10’s.

When we multiply by 10 we can call it multiplying by a power of 10 Complete the second column of Day 22 “Exploring Power of 10” Working together, let’s discuss Day 22, “Exploring Multiplying by a Power of 10 with Whole Numbers” Day 22, “Exploring the Power of 10 with Decimals”

What if I wanted to DIVIDE by powers of 10? Day 22, “Exploring Division by a Power of Ten with Whole Numbers”  When we multiply by powers of 10’s the number becomes 10 times bigger. When we divide by 10’s the number becomes 10 times smaller.

Day 22, “Exploring Division by a Power of 10” Let’s complete the first problem together as a model. Complete the rest of the table. You may work with a partner!!

Extra Support Get hundreds, tens, and ones blocks. We are going to prove 3 x 103 = 300. Take 3 ones cubes. If you were going to multiply this number times 10, what would it look like. Create 10 groups of 3 cubes to equal 30 cubes. Then exchange the thirty ones cubes for 3 tens sticks. What if I took my new number of 30 and multiplied that times 10. Make 10 groups of 30 tens sticks and then exchange them for the correct number of hundreds blocks – 3 hundreds. Based on this, what if I wanted to multiply 3 x 103. How do you know that the answer would be 1000?
