Metric SystemStudents will be able to convert between units in the metric system

What is the metric system?

The first standardized system of measurement, based on the decimal

What are the metric measurements that we are learning about? Meter (m)

Length Liter (L)

Volume Gram (g)

Weight or Mass

Seconds (s) Time

Celsius (C) Temperature

Gram (g) Weight or Mass

Temperature Freezing: 0° C Boiling: 100° C

How to remember different lengths in the metric system: When you think of a millimeter (mm) think

of: The thickness of a dime.

When you think of a centimeter (cm) think of: The width of your pinky.

How to remember different lengths in the metric system: When you think of a meter (m) think of:

When you think of a kilometer (km) think of: A little more than half of a mile

How to understand the ruler: One side has inches (duh!) The other side is the metric side.

The big numbers represent centimeters The smaller lines represent millimeters. How many millimeters are in a centimeter?

How to remember different volumes in the metric system: When you think of a liter (L) think of:

About the size of a bottle of water.

When you think of 5 milliliters (mL) think of: One teaspoon

When you think of 2 kiloliters (kL) think of: A hot tub

How to remember different masses in the metric system: When you think of a gram (g) think of:

Ladder Method

How do you use the “ladder” method?

1st – Determine your starting point.

2nd – Count the “jumps” to your ending point.

3rd – Move the decimal the same number of jumps in the same direction.

4 km = _________ m

12

3

How many jumps does it take?

Starting Point Ending Point

4.1

__.2

__.3

__. = 4000 m

Try these conversions using the ladder method.

1000 mg = _____ g 1 L = _____ mL160 cm = _______ mm

14 km = _______ m 109 g = _______ kg 250 m = _______ km

Conversion Practice

Now you try: 7 km = __________ m 6 g = __________ cg 9.15 kL = __________ L 6.25 kg = __________ mg 14.2 m = __________ cm

Now you try: 7 km = __7000________ m 6 g = ____600______ cg 9.15 kL = ___9150_______ L 6.25 kg = __6250000________ mg 14.2 m = __1420________ cm

Now you try: 14 mL = __________ L 3.97 g = __________ kg 915 L = __________ kL 45 mg = __________ dag 10 m = __________ dam

Now you try: 14 mL = __.014________ L 3.97 g = ____.00397______ kg 915 L = _____.915_____ kL 45 mg = ____.0045______ dag 10 m = ____1.0______ dam
