# Maths

Keep practising the 3D shapes we introduced last week:

This week you could talk to your child about the words “face,” “edge” and “vertex.” Children do not have to be able to use this vocabulary at this age but it is useful for them to experience and be exposed to these words. A “face” is the flat or curved surfaces of a 3D shape. An “edge” is a line where two faces meet which can be straight (one cube) or curved (on a cylinder). You can run your finger along them. A “vertex” is the pointy bit where two or more edges meet like the points of a cube or a cuboid. Be aware that a cone does not have a vertex. The pointy bit is part of the curved face, not where edges meet.

• True or False: hold up a shape and say a shape name (correct or incorrect) and ask your child to say if the name you gave was true (with a thumbs up) or false (with a thumbs down).
• 3D-Shape walk: On your daily exercise walk, see what 3D shapes you can spot and talk about them. You might like to take a photo. E.g. cylinder post box, cylinder car wheels, a cube house, a sphere ball in someone’s garden.
• Use recycled materials to build your own city skyline for a superhero to protect or to make a superhero vehicle like the Batmobile, talking about the shapes you have chosen and why they are good. E.g. I am using a pringles tube to be a big wheel across the bottom because it rolls.

• Supermarket Maths: make price labels or stickers for food in your house and set up your own role play supermarket from Supertato. You could could use real money, pretend money or draw/make your own (You might like to just use pennies and choose prices below 10p so you child can count out the coins). Talk about how much things cost and how much all together. This is also a good chance to practise saying 'please' and 'thank you'. Extension: talking about giving change.
