A homemade balance for learning about weight (non-standardized measurement)

We recently covered non-standardized measurement in math. I do not have balance at home, so I decided to make one from items we already had in our home. It turned out to be so easy, and worked just fine for our purpose of comparing the weight of different objects, as well as using units of weight (for example marbles or clothing pegs) to compare the weight of different items (for example, a pen weighs 2 units and a toy car weights 5 units).

Here’s how we did it:

Stick a ruler onto a table, with the end jutting over the edge of the table.
