Metric System Students 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: The height of the doorknob.  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? 10

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: A paper clip  When you think of a kilogram (kg) think of: A little more than 2 pounds.

What is the order of the metric system?  King Henry Died by Drinking Chocolate Milk King: Kilo (k) Henry: Hecto (h) Died: Deka (da) By: Base (m, L, g) Drinking: Deci (d) Chocolate: Centi (c) Milk: Milli (m)

KILO 1000 Units HECTO 100 Units DEKA 10 Units DECI 0.1 Unit CENTI 0.01 Unit MILLI 0.001 Unit Meters Liters Grams Ladder Method How do you use the “ladder” method? 1 st – Determine your starting point. 2 nd – Count the “jumps” to your ending point. 3 rd – Move the decimal the same number of jumps in the same direction. 4 km = _________ m 1 2 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 = _____ mL 160 cm = _______ mm 14 km = _______ m109 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
