## 3. Anamorphic Cube

February 11, 2016

This is quite a challenge. The idea is to draw an anamorphic cube so that the image, once projected onto a curved surface looks like a cube. You will find the template or graph for this exercise on Mathspig here.

It took me several goes to get it … sort of … right.

Step 1: Make silver foil/cardboard cylinder to fit the dotted circle on the grid below.

Step 2: Draw in the corners of the cube on the square grid and match these corners on the curved grid.

Step 3: Draw in the three vertical sides of the cube and match these lines on the curved grid.

Step 4: Draw in the top and bottom horizontal sides of the cube on the square grid and match these on the curved grid.

Getting tricky now.

Step 5: Draw in the blue, orange and green sides of the cube on the square grid and match these on the curved grid.

Step 6: Place silver cylinder on dotted circle.

Step 7: Can you see the cube?

Step 8: Here’s a closer look.

An even better Anamorphic Cube.

## 6. EDIBLE CUBE

February 5, 2016

Now mathspiggies you may not want to do this in the maths classroom, but you could set this exercise as a homework project. Make it a general challenge.

eg. Homework Challenge: Make a cube out of edible products and photograph results.

You will find out how to make a Fruit Salad Cube

on WikiHow … Do you need instructions?

Rubik’s Cube Birthday Cake

for Sweet 16

You have to lerv a BORG CUBE CAKE.

It’s got lights and everything!

RESISTANCE IS FUTILE!

You can grow fruit and some vegetables in square containers,

but this project would take a very, very long time!

This is a Wonka Gobstopper Cube by Candydood.

You can work out how many gobstoppers it took to make the cube.

Yeah! 10x10x10!  That stops a lot of gobs.

I’m not sure if you can eat it. I suspect

glue may be the secret of success here.

## 7. GIANT CUBE

It would be possible to construct drawings like the following in the school grounds using chalk and/or string. The students have to work out how to construct these drawings themselves. Then you can take some AWESOME photos.
