Lesson Plan : Color Tiles

Color Tiles (Area and Perimeter of My Pool)

NJCCS
4.3 Color Tiles
3. Identify that rectangles with same perimeter may have different areas.
Entry Skills:
Students should be familiar with calculating area and perimeter of a rectangle.

Strategies Utilized for Achieving Objectives
• Direct Instruction
• Modeling
• Guided Practice
• Independent Practice
• Cooperative Learning

Materials: paper, pen/pencil, color tiles, calculator


Introduction:
Students use color tiles to investigate ways to create a shape that has a perimeter with the greatest possible area. Students should recognize that rectangles with the same perimeter may have different areas. Find ways to compare the area of different shapes.
Procedure:
• Ask the students “How many different rectangles can you make using 30 tiles?”
• Have the students come up with a conclusion about how many different rectangles can be made using 30 tiles. Have students come up with which combination has the greatest area and/or perimeter.
• Have the students show and explain their conclusions.
• Come up with a relation between area and perimeter
• Come to a conclusion of which combination if a rectangle would be show the greatest area? What about another shape?

Follow Up Discussion:
A group discussion will occur following the 5 minute exercise. Students will be asked to verbalize their solutions and show their chart on the board or on the overhead.

Assessment:
Assessment and understanding will be based on participation in the activity and class discussion. Students will be worksheet on various polygons and determine the degree of measurement.
