# Introduce Circumference and Area Formulas

- Review methods for finding and identifying the area of rectangles/parallelograms, triangles, trapezoids, rhombi’s/kites and circles (including circumference for circles).
- Use real-world shapes and have students compute the area for these shapes.
- Students brainstorm on how circumference and area will be displayed in their presentations.

## Tips and Tools

See Curriki for this video on perimeter and circumference. (1 minute)

Highlight Mathematical Practice 7, *look for and make use of structure*, on the Mathematical Practices Rubric.

If time permits, have students brainstorm real-world examples and compute their area. This is also an opportunity to tour the school and observe/measure.
