Activity for all ages!

This activity is one very good idea and is appropriate for any level. Ask the question:

'The answer is 10 (or any number), what’s the question? '

Possible responses:

·         8 plus 2

·         5 x 2

·         25 - 15

·         2.5 times 4

·         the number before 11

·         9999 subtract 9989

This is a brilliant activity because: there's no failure; it stimulates thinking and it stretches knowledge of numbers and mathematical relationships; it's good fun.
