In this lesson, we will learn:

- The patterns in multiplying by 10, 100 and 1000 (and their multiples)

- A multiple of 10 is any number that has 10 as a factor (Shortcut: a multiple of 10 is any number that ends in zero)
- To multiply a whole number and 10, 100, 1000 (or their multiples)
- Multiply the nonzero digits
- Count the number of zeroes in the factors
- Write the same number of zeroes in the product

$\qquad \quad$ Ex. 30 x 7 00 = 21000

$\qquad \quad$ Ex. 800 x 4000 = 3,200,000

**Multiplying by 10, 100, 1000**

Multiply:a)62 x 10b)9 x 100c)78 x 1000 - 2.
**Multiplying by 10**

Multiply:a)3 x 80b)40 x 50c)4 x 900d)500 x 600e)6000 x 9000 - 3.
**Use the Pattern of Multiplying by 10, 100, 1000 to find the missing number**

Find the missing numbera)20 x _____ = 600b)30 x ______ = 120, 000c)______ x 400 = 8000d)600 x _____ = 30000e)______ x 70 = 210,000
