This activity is based on an idea from the book "More Mathematical Curiosities" published by Tarquin - see below for details.
Follow the instructions below to make your square:
You will need:
What to do:
Before you try the double-sided puzzle, it is worth having a go at the magic square on just one side.
You need to arrange the numbers $1-16$ in a $4$ by $4$ grid so that:
When you've done that (there are $48$ different ways of doing it!), you're ready to have a go at the Double-Sided Magic Square.
Slip the squares inside the plastic wallet so that you can see both sides.
The challenge now is to make sure both sides of the square obey the rules above.
The colours of the squares give you a clue to the arrangement:
To make a 3D version of the square, look at "More Mathematical Curiosities" published by Tarquin. It is priced at £4.95 and can be ordered directly from Tarquin Publications: http://www.tarquinbooks.com
These two group activities use mathematical reasoning - one is numerical, one geometric.
An investigation involving adding and subtracting sets of consecutive numbers. Lots to find out, lots to explore.
