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.

Polygon activity  decomposition and composition B 2/2

Polygon activity decomposition and composition B 2/2

  • Lesson Aims
  • The pupils will fold and identify shapes according to their properties.

    The pupils will use paper folding in order to make geometric shapes and investigate their properties.

  • Name of Model
  • A rabbit finger puppet

  • Lesson content
  • In this lesson the pupils investigate polygons that are formed during the folding process. There is a surprise at the end of the lesson.  The pupils learn new concepts and refresh their previous learning.

  • Prior knowledge
  • If during the folding process there are cases of inexact folding by some of the pupils, then these cases will be used to identify differences between the polygons and their properties. The pupils will also learn the concept of polygon sides and vertices.
