VT's FREE Newsletter for Educators - Insight, Inspiration and Ideas that Work!


Hello Everyone,
I had such fun just recently with a kindergarten class. We were working on CELEBRATIONS.
Just the thing for a busy afternoon. We danced and chatted and watch fireworks and then drew wonderful firework pictures.
October 21st is Tri-hexaflexagon Day in honour of the great Mathematician.
I will be travelling to Europe in November to fulfill some speaking engagements and visit a few schools. Hope to catch up with other European readers of VT as well.
Thanks to all the recent purchasers of Do You Need a Hammer to do Multiplication?

2. Make a paper loop. How many sides does it have? (2) Draw along the middle of the middle of the loop.
3. Predict what will happen when you cut along the line (you get 2 loops)
4. Cut along the line. See if you are right.

5. Make a paper loop with a twist to create Mobius loop. How many sides does it have? (1) Draw along the middle of the middle of the loop.
6. Predict what will happen when you cut along the line (you get 1 loop)
7. Cut along the line. See if you are right.

8. Make a paper loop with a twist to create Mobius loop. draw a line 1/3 up from the bottom of the strip.
9. Predict what will happen when you cut along the line (you get 2 loops one small and one large)
10. Cut along the line. See if you are right.

Or you can watch the video and pause it to complete the activities.

Many of these investigations are investigations into Mathematical topology
Topology is the mathematical study of the properties that are preserved through deformations, twistings, and stretchings of objects. A circle is topologically equivalent to an ellipse (into which it can be deformed by stretching) and a sphere is equivalent to an ellipsoid.
