2. Every Measurement Consists of two things
A number
A unit of measure
Number
Unit

3. Standards
A standard is: something set up and established by authority as a rule for the measure of quantity, weight, extent, value, or quality
Example:The CHARLIE Stick
The room is _________Charlies by _________Charlies
Standard is an amount everyone agrees on
Ex Feet, Meter, Liter, Quart, Gram, Pound, ex
Kelly stick - length of Mr. Kelly's arms

4. Floor covering Activity
The school board would like to replace the flooring in the room with nonslip tiling
The cost of flooring is $20 per square meter
1. Form your construction company name
2. Measure the room and come up with an estimate for the cost of materials
Have students calculate cost

5. Precision and Accuracy
Examples:
Percision - how close values are together
Accuracy - how close to actual value
Use Ex. from flooring activity

6. Precision and Accuracy
Precision: The ability of a measurement to be consistently reproduced
Accuracy
Examples:
Percision - how close values are together
Accuracy - how close to actual value
Use Ex. from flooring activity

7. Precision and Accuracy
Precision: The ability of a measurement to be consistently reproduced
Accuracy: The ability of a measurement to match the actual value of the quantity being measured
Examples:
Percision - how close values are together
Accuracy - how close to actual value
Use Ex. from flooring activity

20. Relationship between distance, volume, and mass
1 cm3 = 1 mL
1 mL of water = 1 g
Compare cm3, Dcm3, m3

21. Converting between systems
equality/conversion factor method
an equality is:
a conversion factor is:
Conversions in student planner
1 inch = 2.54 cm
(1inch/2.54 cm, 2.54 cm/1 inch)
12in *2.54cm/in = 30.48cm
Do some examples

22. Converting between systems
equality/conversion factor method
an equality is: a state in which two things or values are always equal
a conversion factor is:
Conversions in student planner
1 inch = 2.54 cm
(1inch/2.54 cm , 2.54 cm/1 inch)
12in *2.54cm/in = 30.48cm
Do some examples

23. Converting between systems
equality/conversion factor method
an equality is: a state in which two things or values are always equal
a conversion factor is: The ratio of a measurement in one unit to the equivalent numerical value in another unit
Conversions in student planner
1 inch = 2.54 cm
(1inch/2.54 cm , 2.54 cm/1 inch)
12in *2.54cm/in = 30.48cm
