So It's 28
Here is your chance to investigate the number 28 using shapes, cubes ... in fact anything at all.
How Many Pieces?
How many loops of string have been used to make these patterns?
Making Shapes
Arrange any number of counters from these 18 on the grid to make a rectangle. What numbers of counters make rectangles? How many different rectangles can you make with each number of counters?
Caterpillars
These caterpillars have 16 parts. What different shapes do they make if each part lies in the small squares of a 4 by 4 square?
Building with Cubes
Try to picture these buildings of cubes in your head. Can you make them to check whether you had imagined them correctly?
Start Cube Drilling
Imagine a 3 by 3 by 3 cube. If you and a friend drill holes in some of the small cubes in the ways described, how many will have holes drilled through them?
Happy Halving
Can you split each of the shapes below in half so that the two parts are exactly the same?
Sorting Logic Blocks
This activity focuses on similarities and differences between shapes.
Poly Plug Rectangles
The computer has made a rectangle and will tell you the number of spots it uses in total. Can you find out where the rectangle is?
Holes
I've made some cubes and some cubes with holes in. This challenge invites you to explore the difference in the number of small cubes I've used. Can you see any patterns?
Four Colours
Kate has eight multilink cubes. She has two red ones, two yellow, two green and two blue. She wants to fit them together to make a cube so that each colour shows on each face just once.
