2. Using SI system A meter-is the basic unit of length in the SI system A meter-is the basic unit of length in the SI system Is based on 10s Is based on 10s A meter is divided into units of tens A meter is divided into units of tens There is 10 decimeters in a meter There is 10 decimeters in a meter There is 100 cm in a meter There is 100 cm in a meter There is 1000 mm in a meter There is 1000 mm in a meter There is 1000000 Micrometers in a meter There is 1000000 Micrometers in a meter There is 1000000000 nanometers in a meter There is 1000000000 nanometers in a meter The prefix for a mm is 1/1000 The prefix for a mm is 1/1000 Years ago people used barley & body parts to measure things Years ago people used barley & body parts to measure things

3. Volume Volume-is the amount of space that something occupies, or the amount of space that something contains Volume-is the amount of space that something occupies, or the amount of space that something contains To figure the volume of something you need to take the length times the width times the height To figure the volume of something you need to take the length times the width times the height A cubic meter (m3) is equal to 1000 liter A cubic meter (m3) is equal to 1000 liter A cubic centimeter (1cm3) is equal to one milliliter A cubic centimeter (1cm3) is equal to one milliliter

4. Mass Mass-is the amount of matter that something is made of Mass-is the amount of matter that something is made of A kilogram is the basic unit of mass A kilogram is the basic unit of mass A medium size apple weighs about 100 grams A medium size apple weighs about 100 grams You would weigh yourself or any other large animals in kilograms You would weigh yourself or any other large animals in kilograms There is 1000 grams in a kilogram There is 1000 grams in a kilogram

5. Temperature Temperature-is a measure of how hot (or cold) something is Temperature-is a measure of how hot (or cold) something is A Kelvin & Celsius is the basic unit of how (hot or cold) something is A Kelvin & Celsius is the basic unit of how (hot or cold) something is Your temperature in Celsius is 37 degrees Your temperature in Celsius is 37 degrees Boiling point in Celsius is 100 degrees Boiling point in Celsius is 100 degrees Freezing is 0 degrees Celsius Freezing is 0 degrees Celsius

6. Math you Need to Know Finding area- Base X Width X Height Finding area- Base X Width X Height Averaging- Add all the numbers together and divide it by the number of numbers that you added together Averaging- Add all the numbers together and divide it by the number of numbers that you added together How much liquid would fill a container 1000 liter =1 meter cubed How much liquid would fill a container 1000 liter =1 meter cubed All sides are equal in length on a cube All sides are equal in length on a cube
