There is a link in this activity to a different site where you will be able to play around with maths.
## Preparation- Print this Investigation Guide.
- You need scissors and a ruler.
- You need a tiny amount of sticky tape or glue.
- You need one (1) envelope.
- Write the title of this challenge and today's date on a fresh page in your maths journal.
## Getting StartedCut the top strip off the Investigation Guide. Save the rest.
## RecordingThe data in this activity is shapes. This is how you record the data you have so far.- Find a way to stick your net flat on your journal page so that
*only one*square is stuck down*and*so you can fold the net to make the cube. - Cut out the other shapes and stick them in too. They can only go flat. Use arrows and words to explain why each one can't fold up.
This is only one net of a cube.
Have fun exploring Cube Nets.
## A Mathematics PlaygroundParents & Teachers
all the other cube nets.
- Each time you find one draw it on your paper and cut it out.
*Don't*paste in your journal yet. Save it in an envelope instead.
## Challenge 3A mathematician's work begins with an interesting problem.A problem is a problem because no one knows the answer ... no one! So when a mathematician finds an answer they also have to be able to explain how they know it's the answer.
- How do you know when you have found all the nets?
Hint: Organise your data. It's in your envelope. Take out the nets you have made so far and try to organise them into groups.
## Extra Challenges- Think of another simple 3D object.
For example a triangle pyramid or a square pyramid or a dog kennel.
- Imagine unfolding it like PolyPad does.
- In your journal sketch the net you imagine.
- Use PolyPad to make the net and fold it up to test your hypothesis.
- Record your experiment so someone else can understand what you imagined and what happened when you used PolyPad.
- Use the whatever you want from the PolyPad toolbox and do whatever you want with the shapes.
Record your experiments - even if they don't work - and anything you discover.
## Just Before You Finish- Read your Working Like A Mathematician page again and write three or more sentences explaining how you worked like a mathematician.
## Answers & DiscussionThese notes were originally written for teachers. We have included them to support parents to help their child learn fromCube Nets. They include photos of students working on the problem in a Year 7 classroom and slide shows of two learners folding up their different nets.
