This week we explored scales. Our class read the book Balancing Act to get an idea of what a see-saw or teeter totter looked like. We then explored how to make our own. We had some trials and mistrials and then we looked at it as a class. What worked? What didn't? How do we get the tray to balance? What would happen if I put a bear counter on one side? How do I get it to balance again?
Each group was given: a tube, sticky tack, and a tray of some sort.
We then explored with real balances. Let's see what we find next week!
