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:

The 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.

While 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!

I enjoy thinking about presenting mathematical concepts to young children in exciting and engaging ways.

Thanks for the idea!!
