Balance the blobs: find the rule 3

Learning Material  |  Interactive Lesson

Published on 2018 August 13th

Balance scales by using blobs. Explore how many black, white and grey blobs balance each other. Discover a set of rules that balances the scales with the correct number and type of blobs. For example, 1 black blob balances 2 white blobs. Then find out how many grey blobs balance 1 black blob. Then use the set of rules to solve a problem by moving blobs to make the scales balance. This learning object is the last in a series of three learning objects.
Students identify the numerical relationship (ratio) between three types of items.
Students investigate multiplicative number sentences to record the equivalent relationships.
