Balance scales by using blobs. Explore how many black blobs and white blobs balance each other. Discover the rule that balances the scales with the correct number and type of blobs. For example, 3 black blobs balance 2 white blobs. Find out how many black blobs balance 4 white blobs. Build a number pattern. Then use the rule to solve a problem by moving blobs to make the scales balance. Go on to balancing scales with black, white and grey blobs. This learning object is the second in a series of three learning objects.
