Parents Numeracy Workshop

Parents Numeracy Workshop

• Session 8
• Angles, 2D 3D Shapes
• Area Perimeter

2
Recognise and estimate anglesUse a protractor to
draw acute and obtuse angles

• Software we use to teach angles estimate
  measure draw.
• Activity sheet 8.1 (Paired activity)
• Draw a set of angles each and swap to check.

3
Types of angles

• Which angles from Set A and Set B will fit
  together to make a right angle?
• Which angles will fit together to make a straight
  line?
• What four angles add together to make a complete
  turn?

4
If a is 40 degrees, b is 110 degrees, c is 130
degrees, what is d?
5
Describe and visualise properties of solid
shapes.Visualise 3D shapes from 2D drawings and
identify different nets for a closed cube.

• Using cm2 paper, sketch the net for this
  cereal box (not to scale).

6

• Vocabulary check
• Distinction between cube and cuboid
• Draw a net of a closed cube with dimensions
  3cmx3cmx3cm
• Could this net work?

7

• How many other nets can you find for a 3cm
  cube, recording your ideas to scale on cm2 paper?

8
To visualise 3D shapes from 2D drawings
All four diagrams are different views of the same
shape. Make the shape. How many cubes are needed?
9
How many cubes could be used to make the
shape? Any there any cubes we cannot see?
How many cubes now? How many more cubes are
needed to make a cuboid?
10
Calculate the perimeter and area of simple
compound shapes that can be split into rectangles.
What information do we need to find out the
perimeter and area of this shape? Work though
examples from given dimensions.
