Estimate the area of a circle using graph paper.
Clarifications:
Essential Understandings
Concrete:
- Use a transparency of graph paper to place over a shape. Use the squares on the graph paper to count the area of a circle.
- Use manipulatives, i.e., 1 inch cubes, linking/stacking cubes, to estimate the area of a circle by placing the cubes on top of the circle.
- Given a circle on graph paper, have students count the number of squares that cover the circle. Have students combine partial squares as a part of the count.

Cluster:
Solve real-life and mathematical problems involving angle measure, area, surface area, and volume. (Additional Cluster) :
Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
