Two neighbors build swimming pools. This is what the pools look like.

Family A Family BWhich family has the pool with the bigger swimming area?

Let’s do these problems together.

Area = 8 Area = 7Perimeter = 12 Perimeter = 14

Answer: Family A

APPLICATION:The students will measure the perimeter of each polygons from yesterday’s activity using their ruler and write them down on their student’s handbook

AFTERNOON SESSION:

Field work

Students will go out and measure the perimeters of the canteen's table, covered court, and stage.

EACH GROUP REPRESENTATIVES WILL SHARE THEIR DATA.
