Open Ended Tasks
Tasks are open ended, and far more enjoyable, when there are many ways to
solve a problem, just like a puzzle or a brainteaser.
How would you solve this chance (and measurement) problem which was recently completed with great success in Stage Three?
Spin that Wheel!
I designed a ‘spinner’ with the numbers 1-10
as the outcomes.
One outcome was more likely than all the others.
One outcome had a 25% chance of being chosen.
Three outcomes had an equal chance.
It was highly unlikely that I would spin the #4
What could my spinner have looked like?
Enjoy some hard thinking today!
