Balancing Scales

This week in class we balanced scales. Most kids seemed to already know the concept behind how balancing scales worked, and they had all seen one of these before:

seasaw_GKThe main concept we were trying to get across was the following: If the scales are balanced and you add or remove equal weights to/from both sides, then the scales will remain balanced.

balancing_scales_GKWhile it is a very intuitive concept, it can show up in quite non-trivial ways in problems.

Each kid had a turn balancing something with a real scale.  The hardest thing with the little kids was to prevent them from touching the scales while they were balancing :-).  The older kids also got to solve problems on paper. Try your hand at a few!
