standard_description: Understand that the three digits of a three-digit number represent amounts of hundreds, tens, and ones; e.g., 706 equals 7 hundreds, 0 tens, and 6 ones. Understand the following as special cases:
- 100 can be thought of as a bundle of ten tens — called a “hundred.”
- The numbers 100, 200, 300, 400, 500, 600, 700, 800, 900 refer to one, two, three, four, five, six, seven, eight, or nine hundreds (and 0 tens and 0 ones).
problem_activity: Problem 1
a.   How many do you see? How do you see them?
[IMG]
b.   Instead of writing
$$10 \times 10$$
, we can write
$$10^2$$
, which we read “ten to the
power
of two.” The two is the
exponent
and tells us how many times we multiply 10 by itself. How would you represent the number of the smallest spokes in the image above as a power of 10?
Problem 2
a.   Write each of the following as a product of tens and in standard form.
$$10^4$$
$$10^6$$
b.   Write each of the following as a power of 10.
10 × 10 × 10 × 10 × 10
1,000,000,000
Problem 3
a.   Solve.
10 × 10,000 = ______
1,000 × 1,000 = ______
1,000,000 × 100 = ______
b.   How were powers of 10 useful in solving Part (a)?
