One of the hardest things for children to remember about 3D shapes is their properties. This is often because they cannot visualise the shape. To help with this try and find things around the house for each shape. For example, a pack of pringles is the shape of a cylinder, a packet of cereal is a cuboid, a dice is a cube, etc. When they are asked about the features of the shapes they can then picture each item in their house and think about their properties a lot easier.
3D shapes that we are covering
Sphere, cylinder, cube, cuboid, cone, triangular based pyramid, square based pyramid, triangular prism
2D shapes that we are covering
2D shapes- circle, semi-circle, triangle, square, rectangle, pentagon, hexagon, heptagon and octagon.
Triangle- a tricycle has three wheels.
Semi- means half so half a circle.
Pentagon- a regular pentagon looks like the nib of a pen.
Hexagon- has the x sound as does the number six so it has six sides and six corners.
Octagon- octopuses have eight tentacles so octagons have 8 sides and 8 corners.
