Product Description
Use these interactive notes to introduce students to finding areas of sectors in circles.

The 2-page notes include basic circle vocabulary, review of area, steps for finding sector area, practice, and challenge problems involving shaded regions.

These notes do not use the standard sector area formula. Instead, I try to get students to understand the concept of sector area by calculating the area of a circle, finding a fraction or decimal for the sector’s portion, and then multiplying these two figures.

The pages are meant to be filled in as a class with the teacher aiding some portions and then allowing students to try some practice problems on their own before checking as a group.

Check out the preview!
