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.
