# Metric Mania - Kyrene School District

The Metric System is a system of measurement that is used by scientists all over the world. Most countries only

use the metric system. There are different metric units depending on what we want to measure: Length: Meter

(m) Volume: Liter (l) Mass: Gram (g) These are called basic units. When you add a prefix to a basic unit you change its value. Kilo (k) = 1000 Hecta (h) = 100 Deca (da) = 10

BASE UNIT = 1 Deci (d) = .1 Centi (c) = .01 Milli (m) = .001 Kilo (k) 100 0 Hecta

(h) 100 Deca (da) 10 1

Deci (d) .1 Centi (c) .01 Milli

(m) .00 1 The basic unit of length in the metric system is the meter and is abbreviated using a lowercase m.

Metric Units 1 Kilometer (km) = 1000 meters 1 Meter = 100 Centimeters (cm) 1

Meter = 1000 Millimeters (mm) To measure length, we use a ruler. How many

millimeters are in 1 centimeter? 1 centimeter = 10 millimeters 28 What is the length of the line in millimeters? _______mm What is the length of the line to the nearest centimeter? ________cm ***HINT: Round to the nearest centimeter 3

NO decimals. 37 Length: ________ mm 7.2 Length: ________ cm 5.1

Length: ________ cm 6.2 Length: ________ mm Kilo (k) 100 0

Hecta (h) 100 4.___.___.___. = 4000 m ________ Deca

(da) 10 1 How do you use the Ladder Method? 1.Determine your starting

point. 2.Count the jumps to your ending point 3.Move the decimal the same number of jumps in the same direction Deci (d)

.1 Centi (c) .01 Milli (m) .00

1 4 km= ________ m Ending Starting Point Point How many jumps does it take? 1000 kg= ________ g

1 L = ________ mL 160 cm = ________ mm 14 km = ________ m 250 m = ________ km Side 1: Practicing

Measuring Skills Side 2: Measuring in cm & mm Complete sheet using stated directions Measure each line. On a separate sheet

of paper write the measurement for each line in cm and mm. Attach sheet to homework.
