Area of Regular Polygons Lesson
In this lesson, students will use the area formula to find the area of regular polygons. Students will solve problems using diagrams and word problems.
• Warm-Up -
The warm-up is a review of the previous lesson. There are two questions that ask students to find the arc length and sector area.
• Guided Notes -
Two versions are included: mostly complete and fill-in-the-blank. The notes are 2 pages long. Examples are included throughout. The lesson begins using regular polygons that use special right triangles. The last two examples require trig.
• Practice Presentation -
A PDF presentation is included to use as in-class student practice. Students could work the problems on whiteboards. Since it is a PDF, the "slides" could be written on using SMART software (or other similar software). There are 8 questions. The presentation is in the format of Question-Answer-Question-Answer-Etc.
• Homework -
The homework is 2 pages and 10 questions.
• Answer Keys -
Completely worked out answer keys are included.
Make sure this lesson is appropriate for your students - see the preview to see some of the pages in the product.
