Angles

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.

Perpendicular Line 

Perpendicular Line 

  • Lesson Aims
  • Pupils will recognise perpendicular lines and draw perpendicular lines.

  • Name of Model
  • The swimming fish.

  • The Lesson Structure
  • The measuring tool,Composition and Decomposition of Shapes, Polygons 3,Perpendicular  lines and sides of polygons.
