Lesson Snapshot

1. Engage: Students will predict the amount of time it would take to cover the bathroom floor with water, followed by reading of the book Counting on Frank.

2. Explore: Students will collaborate to find the smallest and largest area with identical perimeter using manipulatives and grid paper. 

3. Explain: Students will explore their findings; discuss and justify their answers using words, numbers, pictures, or diagrams to show their reasoning, and present their findings to the class.

4. Extend/Expand:  Students will use different perimeters to test their reasoning of the smallest and largest areas. Students will test the possibility of using a constant area, but varying the perimeter.  Students will calculate area and perimeter within the school using a variety of objects, such as ceiling tiles.  Students will brainstorm and chart testable questions from the book Counting on Frank.  Students will write a letter to the author Rod Clement.  The teacher can use the book Spaghetti and Meatballs for All by Marilyn Burns for another literary resource to reinforce the concept of area and perimeter.

5. Evaluate:  Students will receive feedback on the chart they make documenting and explaining how the size of an area can vary while the same perimeter does not and showing how to determine the smallest area when the perimeter is constant and explanation of the process.
