How do you remember what to do?
2
Perimeter Add all sides of a figure. Think of the lower case t as a + sign. Easily confused with area. Look at the word rim. Where is a rim? The rim goes around the basket. So for perimeter you go around the figure.
3
Perimeter What is the perimeter of the figure below? 33 meters 28 meters
4
Perimeter The race course was a 25 mile marathon. One of the sides of the course is not labeled. What would be the measurement of the side of the race course? 2 miles 6 miles ? miles
5
Perimeter An equilateral triangle has a perimeter of 12 cm. What could be the measurement of each side? Draw your triangle. Remember an equilateral triangle has 3 equal sides.
6
Area Area is the measurement of the number of square units needed to cover a surface Area is found by multiplying length times width or counting squares if they are available Think of area as how much it covers like a blanket. When asked for area think of squares.
7
Area Find the area of the rectangle. 33 meters 8 meters
8
Area Sally was going to buy carpet for her living room. The carpet was $8 a yard. Below are the measurements for her living room. How much was the new carpet going to cost her? 30 feet 24 feet
9
Volume Volume is like an Ogre …it has layers. Volume is the measure of the number of cubic units needed to fill the space occupied by a solid Take the area and multiply it times the number of layers (height)- think of layers when you see the l in volume Volume formula – length x width (area) x height Count the boxes on the first layer then multiply times the number of layers The volume of the box below is Length – 5 cm Width – 4 cm Height – 2 cm
10
Volume What is the volume of a swimming pool with a width of 25 m, a length of 20 m and a height of 3 m?
11
Volume One of the flower beds will have a stone wall built at the corner. The stone wall needs to have a concrete foundation. There is a drawing for the trench that will be filled with concrete. Calculate the volume of concrete that will be needed. 25 feet 3 feet 5 feet

Reflection In the reflection section of your journal, write the difference between perimeter, area, and volume, how to solve them, and how you plan on remembering which is which.
