Introduction to Visual Representation of Angles-1/3

Introduction to Visual Representation of Angles-1/3

  • Lesson Aims
  • The first lesson for the learning of the concept of angle using the mouse shaped made in the lesson as an aide.

  • Name of Model
  • A mouse.

  • Lesson Structure
  • The mouse,circle and angle as a measure of rotation.

  • Lesson Content
  • This lesson is the first of three lessons teaching the concept of angle. Through the folding process the pupils have a dynamic experience of this concept. The idea of measure of rotation as a method of understanding the concept of angle is applied with moving the mouse shape clockwise. This method and definition of an angle as a measure of rotation is understood while creating the angle by the rotational movement. Two mice are folded-one to take home and the other for the next lesson on the subject of angle.

Angles-2/3

Angles-2/3

  • Lesson Aims
  • The pupils will construct a circle using the measuring tool  and marking dots at equal distances.

  • Name of Model
  • Circle.

  • Lesson Structure
  • Mouse and circle.

  • Lesson Content
  • This is the second lesson in learning the concept of angle as a measure of a rotation. The following lesson will make use of the mouse and circle of the the two previous lessons to fully understand the dynamic approach of folding in order to see the formation of an angle as a process of rotation. It is suggested that the pupils make several circles.
