Maths

Last week you thought about 2D “flat” shapes. This week we are going to move on 3D “solid” shapes. Talk to your child about 3D shapes being solid and that can pick them up. Below is a picture of the 3D shapes to introduce to your child. Depending on your child's current age and level of knowledge you might want to introduce all of the shapes this week or you might choose to introduce three shapes this week and focus on those, before introducing the other two next week. If you can find real life examples around your house this would be ideal so that you can pick up and feel the items and turn them around. Talk about each shape and whether the faces are flat or curved. Next week we will think about the edges and vertices. You could sort the shapes into flat and curved shapes; have a look for different 2D shapes on the faces of the 3D shapes (e.g. a cube is made of square faces) or look for real life versions in your house.

 

 

Here is a song introducing the shapes which turns them around so you can see that they are not flat (apologies for the American accent. I could not find an English one!):

This one encourages children to think about real-life 3D objects:

Some activities you can do to explore 3D shapes:

  • Describe a 3D shape for your child to guess.
  • Go on a 3D shape hunt around your house. Here are some ideas: Cube: Rubix cube, dice. Cuboid: cereal box, book. Sphere: marble, ball. Cylinder: candle, glue stick. Cone: ice cream cone, folded paper cone. Take a photo of what you find and put it on Tapestry.
  • Put real life 3D objects in a bag and ask your child to put their hand in, feel it and see if they can work out which shape it is.
  • Go through your recycling bin and see what 3D shapes you can find (tins, packets, jars, bottles etc) and do some junk modelling thinking about why each shape suits each purpose. E.g. a cuboid might suit a bridge.

 

  • If you have blocks at home you can draw around the different shapes, press them into dough or print with them using paint (you can wrap them up in cling film to stop the block being ruined) to see what 2D shapes the different faces are.
