2
**Types of Questions Perimeter and area Elapsed time**

Appropriate units of measure Estimation and calculation Using a calendar Comparison

3
**Perimeter What is perimeter?**

What do you need to know to calculate perimeter? What is the perimeter of the following shape:

4
Perimeter (Cont.) Which of the following has the same perimeter as the shape on the previous slide:

5
Perimeter (Cont.) If the perimeter of the shape is 25 ft., what is the length of the right side?

6
**Area What is area? What do you need to know to calculate area?**

You may get an easy question like this: What is the area in units?

7
**Area (Cont.) This is what you are most likely to see:**

8
**Area (Cont.) Another way you will see this type of problem:**

Elapsed Time (Cont.) How much time is there between the end of “Finding Nemo” and the beginning of “The Little Mermaid”?

11
**Strategies for Elapsed Time**

Use a clock in the room. Draw a timeline. Add and subtract time, but remember to regroup using 60 minutes in an hour.

12
**Using Area and Elapsed Time**

Some questions will give you a surface area that is a fraction of a bigger area. They will give you a time that it will take for the original surface area and ask you to calculate or estimate the time to “finish” the remaining area.
