Angles
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.
