Lesson Plan

Ollie (or Sphero) for Interior Angles of Regular Polygons

Students create a code to make a robot create a regular polygon depending on the number of signs that they enter into their code.

Objectives

Students will be able to...

  • solve problems determining the interior angles of regular polygons 

Student Challenge - figure out how to make Mr. Ollie create a regular polygon with 5 sides using the TickleApp. How about 6? 7? 8? 21? Is there a way that the same program (code) could work for all regular polygons if you entered in the number of sides?

1 Create Code - Challenge

Students use the Tickle app on phones or iPads to complete a challenge. 

Try putting the challenge like this: 

You are challenged to figure out how to make Mr. Ollie create a regular polygon with 5 sides using the TickleApp. How about 6? 7? 8? 21? Is there a way that the same program (code) could work for all regular polygons if you entered in the number of sides?

 

2 Consolidation

Activity: Other — Consolidating and Sharing

Students share their codes and show their Spheros traveling the polygons.  Teacher consolidates the codes into formulas for students. 

3 Practice

Activity: Assessing

Students can do some practice questions finding the interior angle of regular polygons and self-assessing their work.
