Year 9: Turtle Introduction

by Peter Fox

Objectives

From a standards perspective, students developing an algorithm for an animation of a geometric construction and evaluate the algorithm using test cases. On a much deeper level, students create beautiful mathematical images, learn about the internal and external angles of a regular polygon and learn the difference between ‘real world’ and ‘maths world’.

Vocabulary

  • Algorithm
  • Code
  • Loop
  • Function
  • Interior Angle
  • Exterior Angle

About the Lesson

Students learn how to write some simple code, including the use of terms such as loop, function and variable. They create a formula for the exterior angle of any regular polygon and use it to simplify their code.
