Task 1: Mass and Number

Mass tells us how much something weighs. Think about what we can use to find the mass of an object? One thing we have been using in the classroom is a pan balance.

Click on the pan balance picture beside to experiment with balancing equal amounts. How many different ways can you create 3, 4 and 5 grams?

Both sides of the pan balance need to be equal to find the mass of something. Help find the mass of the rocks using copper weights through playing the game beside.

Your next challenge is to use the pictured pan balances in your choice of worksheets below to find equal equations, using the given numbers.

For example, 4+5 balances 2+7
