**We will multiply by multiples of 10, 100, and 1000.**

Name Learning Objective We will multiply by multiples of 10, 100, and 1000. What are we going to learn? CFU Activate Prior Knowledge Multiples of 10: 10, 20, 30, 40, … , 80, 90, … Multiples of 100: 100, 200, 300, … , 1600, 1700, … Multiples of 1000: 1000, 2000, 3000, … ,18000, … Write the number as an amount of tens, hundreds, or thousands. 1.) 2.) Students, you already know how to write numbers as an amount of tens, hundreds, or thousands. Now, we will multiply by multiples of 10, 100, and 1000. Make Connection

Concept Development 1 To multiply is to do repeated addition of equal groups. Factors are the numbers being multiplied. The product is the answer to the multiplication problem. There is a place-value strategy1 for multiplying by multiples of 10, 100, and 1000. 7 400 = 2,800 factors product 3 500 = 1,500 3 5 hundreds 15 hundreds 3 groups of 500 500 + 500 + 500 Cannot use the place-value strategy above to multiply: Go to Skill Dev 1 3 518 518 is not a multiple of 10, 100, or 1000 For the multiplication problem above, which are the factors? Which is the product? The factors are ____________. The product is _____________. Which multiplication problem can be solved using the place-value strategy you just learned? How do you know?
