Objectives

  1. Identify attributes of 3D shapes
  2. Identify differences between 2D and 3D
  3. To develop the skill of model making.
  4. To give an opportunity to develop eye hand co-ordination, Spatial skills and fine motor skills.

Estimated Time

90 minutes

Prerequisites/Instructions, prior preparations, if any

Prior knowledge about 2D shapes and its properties

Materials/ Resources needed

  • Scissors
  • Instrumental box
  • Papers
  • Gum/Glue

Process (How to do the activity)

  1. Ask 3 groups to do one 3D shape (Cuboid, Cube, Cylinder)
  2. Distribute colour a4 sheets, glue and scissors to each group
  3. Each group will be assigned with one instructor who gives instructions on model making to the students
  4. Each student in a group needs to fallow the instructions of their instructor and make the models accordingly

Instructions for making Cube:

  1. Take a piece of paper (A4 sheet)
  2. In the centre of your paper, draw a long rectangle and divide it up into four 2 inch squares.
  3. Draw another square to the right of the second square from the top.
  4. Draw another square to the left of the second square from the top.
  5. After that you can see a cross with six equal sized squares and the longest part should be closest to you.
  6. With scissors, cut along the outside edges of the shape
  7. Fold the paper-Follow along the inside lines, and fold the paper
  8. Study the properties of a cube.

Developmental Questions:

  1. How many sides does a cube have ?
  2. Are all sides the same ?
  3. Point to its vertices. How many vertices does a cube have ?
  4. Point to its edges and faces. How many are there ?
  5. What is the shape of each of its face ? So how many squares are there in a cube ?
  6. What are the properties of a cube ?

Instructions for making Cuboid:

  1. Take a piece of paper (A4 sheet)
  2. In the centre of your paper, draw a long rectangle and divide it up into four same sized Rectangles.
  3. Draw the square to the right of the second Rectangle from the top.
  4. Draw another square to the left of the second Rectangle from the top.
  5. With scissors, cut along the outside edges of the shape
  6. Fold the paper-Follow along the inside lines, and fold the paper
  7. Study the properties of a cuboid.

Developmental Questions:

  1. How many sides does a cuboid have ?
  2. Are all sides the same ?
  3. Point to its vertices. How many vertices does a cuboid have ?
  4. Point to its edges and faces. How many are there ?
  5. What is the shape of each of its face ? So how many squares and rectangles are there in a cuboid ?
  6. What are the properties of a cuboid ?

Instructions for making Cylinder:

  1. Determine the height you want for your cylinder.
  2. Measure the paper and cut it to the desired dimension, as needed. For example, cut your paper, so two sides are 6 inches long for a 6-inch cylinder
  3. Place small tabs of tape on one end of the paper. The tape goes on the sides perpendicular to those you measured for the height.
  4. Roll the paper until the cylinder is the desired diameter.
  5. Cut two circles with the same diameter as the cylinder. Paste circles on both ends of the cylinder.

Developmental Questions:

  1. How many bases are in a cylinder?
  2. What are the properties of a cylinder?

Application Question :

Evaluation at the end of the activity

  1. List objects similar to a cube, cuboid and cylinder shape from your surroundings ?
