1. Using Exponents to Write Large Numbers
By Monica Yuskaitis

2. For Learning to Happen! Clear your desk of anything that may
distract you.
Remove all other thoughts from your
mind.
Pay close attention.
Try all the examples.
Ignore all other distractions.

3. What Is the Standard Form
Exponents of Ten
What Is the Standard Form
of These Tens? 2
100 10 3
1,000 4
10,000 5
100,000

4. Exponents of Ten
Notice that the number of zeros
matches the exponent number 2
100 10 3
1,000 4
10,000 5
100,000

5. Multiplying Multiples of Ten
Multiply These Numbers
100 x 2 =
200
1,000 x 3 =
3,000
10,000 x 7 =
70,000
100,000 x 9 =
900,000

6. Multiplying Multiples of Ten
Did you notice that all you
have to do is multiply 1 x whole
number & add the zeros behind?
100 x 2 =
200
1,000 x 3 =
3,000
10,000 x 7 =
70,000
100,000 x 9 =
900,000

7. Short Cut for Writing Large Numbers
Combine these two steps for
writing large numbers.
6 x 10 2
600 =
6 x (10 x 10) = 6 x 100 = 600

8. Short Cut for Writing Large Numbers
Remember!
The exponent is the same as the number of zeros. 2
6 x 10
600 =
