What is Area?
## Student PageTeacher Lesson Plan## Objectives:- To understand that
**area**is measured in**square**units.
- To learn that the
**area**of a rectangle can be found by counting the number of**squares**.
- To understand that
**perimeter**is measured in**linear**units.
- To learn that the
**perimeter**of a rectangle can be found by counting the**units**around the outside of the figure.
## Materials:- one bucket of 1 inch square tiles
- one sheet of grid paper - 1 inch size
- four sheets of grid paper - 1 centimeter size
- four pencils
- (optional) colored pencils/pens/crayons
- Hands-On Math software by Ventura Educational Systems
(for each group of four students) ## Classroom ProcedureAs a group, using the 1 inch square tiles and the 1 inch size grid paper, build a rectangle with an area of 4 square units. Some groups may have arranged their tiles to show a 2x2 square. Others may have made a 4x1 rectangle or a 1x4 rectangle. All three of the examples are correct.
On your individal sheet of graph paper, draw the model and label it like this:
Here are nine more problems. - Area = 9 square units
- Area = 10 square units
- Area = 25 square units
- Area = 14 square units
- Area = 36 square units
- Area = 18 square units
- Area = 20 square units
- Area = 2 square units
- Area = 49 square units
Each student should draw the answer and label A(rea) and P(erimeter) on their individual sheet of graph paper.
