P3 did the Three Monkeys Addition Problem
Three monkeys ate a total of 25 nuts,
Each of them ate a different odd number of nuts.
How many nuts did each monkey eat?
Some of our answers:
5 + 3 + 17 = 25
5 + 9 + 11 = 25
19 + 1 + 5 = 25
7 + 5 + 13 = 25
7 + 3 + 15 = 25
1 + 9 + 15 = 25
1 + 11 + 13 = 25
We found that
- using cubes helped some pairs
- using bonds of ten and twenty helped
- after we used a bond of twenty plus 5 we could use it again to make a bond of 10 plus 15 e.g. 7 + 13 + 5 so 7 + 3 + 15
It was fun!
