Recently Koka Ngaire has challenged us with puzzles in EL4 Maths Strand... we have had measurement, algebra, geometry and statistics puzzles.
The very first puzzle was 'The Farmer's Sheep' from NZ Maths.
After Koka Ngaire shared this with us and we had read the problem we wanted to:
- give the sheep back
- hide the sheep
- eat the sheep!!!
In other words - we thought the problem was HARD!
Some of us persevered and started working with random number combinations, others got some equipment out to move around. Suddenly, someone had THE answer.
THE answer got shared - however, someone else had THE answer - but it was different! There was a LOT of discussion.... someone else figured out another answer!
We shared our strategies and our different answers... we got LOTS of answers. So, we brainstormed what was helpful and tricky and why.
There were so many different answers that were ALL correct!
What we discovered:
- all the corners added to 11 no matter what combination we used
- sometimes there is more than one answer
|
Some of our combinations.... the crossed out ones did not fit the criteria |
|
What we learnt... and yet MORE combinations! |
HOW MANY DIFFERENT WAYS CAN YOU FIND?!
