Place the numbers 1 to 10 in the circles so that each number
is the difference between the two numbers just below it.
Example: 6 – 5 = 1
It will take some perseverance. You can try different solutions by cutting out numbers to
move around on the circles or you can use the interactive area of http://nrich.maths.org/927.
Solutions are to be completed by Thursday 30th June.
Please post them into the Maths Challenge Box in the picture book
library.
