What does the cube look like?

I created this worksheet based on a problem on the excellent NRich Maths website.

The pupils have to use their skills of visualising 3D shapes to draw patterns on the faces of a cube net after deciphering where they should go by looking at 3D views of the cube. To scaffold the task an actual cube net is also included so they can build what they think is the right solution. There is a nice extension for the future engineers who have excellent visualisation skills.

I found this to work well with medium-to-high attaining year 7 and 8 classes.

Wanna be in my gang?

A great little game to get kids thinking about types of numbers.

Think of a particular type of numbers that you want the pupils to guess. This could be square numbers, cube numbers, triangle numbers, even numbers etc… Tell the pupils that they need to guess a number between 0 and 100. If their number matches your hidden criteria then you say “you’re in my gang”. If the number doesn’t match your hidden criteria then you say “you’re not in my gang”. The pupils keep guessing until they work out what type of numbers you are thinking of.

Big thanks to Nicola for this great idea.
