6. III. Conversions; Metric-
Metric
A. How to do it:
1. We are ONLY MOVING THE DECIMAL!!!!!
2. Here’s how:
1. Look at the order of the prefixes
2. Begin at the prefix that you start with
3. Move to the prefix you want to end with
4. Move the decimal in the number in the same
direction and the same number of times you
moved on your graphic organizer

7. B. Example:
1. Convert 1102 meters to
kilometers
Kilo Hecto Deka Meter Deci Centi Milli
(k) (h) (da) (d) (c) (m)

with a metric ruler.

22. CHALLENGE!
What happens to an inchworm when we use metrics?
To find the answer, lay a ruler across the right side of
a piece of paper. Find the correct mark on the ruler
for each letter. Write the letter above the ruler.
H = 6.8 cm R = 208 mm
G = 23.2 cm, 92 mm O = 14 cm
U = 224mm N = 8.4 cm, 12.4 cm
C = 6 cm A = 76 mm, 156mm
E = 1 dm, 2dm B = 216 mm
L = 4 cm, 17.6 cm, 32mm ‘ = 24mm
T = 192mm, 132 mm, 16mm
I = 11.6 cm, 18.4 cm, 8 mm
