Use the 'double-3 down' dominoes to make a square so that each side has eight dots.
Use these four dominoes to make a square that has the same number of dots on each side.
There were chews for 2p, mini eggs for 3p, Chocko bars for 5p and
lollypops for 7p in the sweet shop. What could each of the children
buy with their money?
From Josh of Alameda School, Ampthill,
There are 5 presents in the second pile, 2 presents in the first
pile, 3 presents in the third pile and 10 in the fourth pile.
I worked it out by saying the second pile equalled x. The first
pile would then be x-3, the third pile x-2 and the fourth pile was
Simplified this gave me 5x-5 = 20. So 5x = 20+5. 5x = 25. And so
x, the number of presents in the second pile, is 5.
