We are currently celebrating Maths Week at Scoil Mhuire, and pupils from 4th – 6th class have been working on a selection of maths challenges. Below is one which they had alot of fun with last Friday, and we invite you to try it at home. The pupils from 4th – 6th can share the solution and answer with their families, and we will post both here on Friday, 27th October.
There are 7 girls on a bus.
Each girl has 7 backpacks.
In every backpack, there are 7 big cats.
For every big cat, there are 7 little cats.
How many legs?
Solution
Answer = 10,990
*7 girls = 14 legs
7 x 7 = 49 backpacks
49 x 7 = 343 big cats
*343 x 4 = 1372 big cats legs
343 x 7 = 2401 little cats
*2401 x 4 = 9604 little cats legs
*14 + 1372 + 9604 = 10,990 legs
