AREA means the whole inside of a figure. To find the Area of a Rectangle, you would multiply the length by the width. The formula for finding the Area of a Rectangle is: Area = Length X Width. You label Area in Units Squared. In the real world, you will need to find the area of a wall that you want to paint, a floor that you want to put a carpet on, or a garden that you want to plant.

PERIMETER means the whole outside of a figure. To find the Perimeter of a Rectangle, you would add up all of the sides. The formula for finding the Perimeter of a Rectangle is: Perimeter = Length + Width + Length + Width. You label Perimeter in Units. In the real world, you will need to find the perimeter of a garden that you want to put a fence around, a yard that you want to build a fence around, or the outside of a card that you want to put a ribbon around.

For Example: When given an 8 foot by 4 foot rectangle. A = 8 X 4, so A = 32 square feet. P = 8 + 4 + 8 + 4, so P = 24 feet.
When given a 14 inch by 6 inch rectangle. A = 14 X 6, so A = 84 square inches. P = 14 + 6 + 14 + 6, so P = 45 inches.

Finding the Length of a Missing Side on a Rectangle when given the Area or Perimeter and the Length of the Other Side...
For Example:
When given an 8 foot by ? foot rectangle with an Area of 32 square feet.
A = 8 X ?, so 32 = 8 X ?, so the missing side is 4 feet.
When given an 8 foot by ? foot rectangle with a Perimeter of 24 feet.
P = 8 + ? + 8 + ?, so 24 = 8 + ? + 8 + ?, so the missing side is 4 feet.

Students are taught to use an open number line or "Time Line", to help them solve the three different types of elapsed time problems that they will come across in the real world.

The Customary System of Measurement:
The Customary System of Measurement:
- Customary System of Measurement (Length):
- 12 inches = 1 foot
- 3 feet = 1 yard
- 1,760 yards = 1 mile
- Customary System of Measurement (Mass; Weight):
- 16 ounces = 1 pound
- 2,000 pounds = 1 Ton
- Customary System of Measurement (Capacity; Volume):
- 4 Quarts = 1 Gallon
- 2 Pints = 1 Quart
- 2 Cups = 1 Pint
- 8 Fluid Ounces = 1 Cup
The Metric System of Measurement:
The Metric System of Measurement:
Base Unit for Length = Meters
Base Unit for Length = Meters
Base Unit for Mass; Weight = Grams
Base Unit for Mass; Weight = Grams
Base Unit for Capacity; Volume = Liters
Base Unit for Capacity; Volume = Liters
- Metric System of Measurement (Length):
- 1 Kilometer = 1,000 Meters
- 1 Meter = 100 Centimeters
- Metric System of Measurement (Mass; Weight):
- 1 Kilogram = 1,000 grams
- Metric System of Measurement (Capacity; Volume):
- 1 Liter = 1,000 Milliliters
This is the diagram we use to help students remember the capacity conversions within the customary measurement system.

Time:
- Time:
- 1 hour = 60 minutes
- 1 minute = 60 seconds
