2-d shapes

2-d shapes

Activity 1

1.  Objectives

Names of 2-D shapes.

Properties of 2-D shapes.

2.  Recall

Do you remember the first time you learned about a circle?  What did you learn about the shape and sides of a circle?  How is a circle different from a square, or a triangle or a rectangle?

3.  Activity

3.1  Using paper, scissors, glue, colouring pencils and a sheet of A3 paper create the following shapes.

1.  A circle

2.  A triangle

3.  A square

4.  A rectangle

5.  A pentagon

6.  A hexagon

7.  A septagon

8.  An octagon

9.  A nonagon

10.  A dodecahedron

3.2  Label the shapes and paste them to the A3 sheet of paper.

3.3  List the following information underneath each shape:

How many sides has the shape?

How many angles has the shape?

What is the value of each angle the shape has?

3.4  Place your finger at a point on the shape.  Run your finger along the perimeter of the shape.  How many turns does your finger make before it comes back to the starting point?

3.5  If the shape is not a triangle, divide 360 by the amount of angles the shape has.  What answer do you get?

4.  Assessment

 Your A3 poster will be assessed on the following criteria:  (100 marks)

4.1  Exactness of each shape.  (30%)

4.2  The names of each shape. (30%)

4.3  The correct properties of each shape, including:

Edges  (10%)

Corners (10%)

Angles (10%)

4.4  The clarity and design of the poster.  (10%)
