This Bundle includes my 3 Regular Polygon Activities/Worksheet
1) Walk Around Activity Finding the Area of Regular Polygons
Objective: Finding the Area of Regular Polygons using the formula A= 1/2 aP or 1/2 asn. Student will need to use trigonometry or special right triangles to find the apothem or the side length on some problems.
This activity also gets students up and about. Place the 10 cards on the wall around your room. Students pick any card to begin with. They should find the area of the figure. Students then look around the room for a card that matches their answer. Then they work the next problem. They should continue until they return to the card they started with.
Included are 2 versions of this activity.
- One with 10 cards for use as a walk-around activity.
- A shorter version with only 5 cards great for table work, bell work or use as a review.
Includes Student Response Pages and Answer Keys with problems worked out.
2) Regular Polygons - Finding the Apothem- Central Angle and Area - 6 Worksheets
>> Identifying Parts of Regular Polygons
>> Central Angles
>> Finding the length of the Apothem
>> Area of a regular polygon (Given both the side length and the apothem)
>> Area of a regular polygon (Given 1 piece - apothem, radius, or side length)
Keys with answers and problems worked out included for all worksheets
These were designed to help student find the area of regular polygons. It works them through the process one step at a time.
3) Matchign Activity - Finding the Apothem of Regular Polygons using Trig
First step to finding the Area of Regular Polygon is to find the length of the apothem.
Matching Activity: Finding the Length of the Apothem
This is a 3-way matching activity. Students use trig or special right triangles to find the measure of the apothem. Students then match the figure to the correct trig function and to the correct length (either as an exact value or an approximation).
