As we are working on expanding our resources in the Maths realm, we thought it would be fun to start a little game here.
Remember “Letters and Numbers” on SBS? (Countdown in UK, Cijfers en Letters in The Netherlands and Belgium, originally Des Chiffres et des Lettres in France).
The core rules for numbers game are: you get 6 numbers, to use with basic operations (add, subtract, multiply, divide) to get as close as possible to a three digit target number. You can only use each number once, but you don’t have to use all numbers. No intermediate result is allowed to be be negative or contain a fraction. Positive integers only, all the way.
Now try this for practice:
Your 6 numbers (4 small, 2 large): 1 9 6 9 25 75
Your target: 316
We’re not worrying about a time limit, as it’s about the problem solving.
If you want, comment on this post with your solution (full working)!
The activities embedded in the programs make the subjects more engaging for the students as well as the teacher.
