Counting by Twelves
There are some very thought-provoking questions that can arise while discussing mathematical ideas with students. Some intriguing questions that have emerged at different times (some repeatedly) in my classroom include:
Why are there 360 degrees in a full circle?
Why are there 60 minutes in an hour (or 60 seconds in a minute)?
Why is our number system based on the number 10 and not some other number?
All very interesting ... but how do you deal with them during class?
