This is a great activity to help students identify equivalent ratios. They can use different strategies such as multiplying both sides or dividing both sides to complete the task. It requires thinking as they are given nothing but the fifteen different ratios to group into triads (groups of three). They can work together in groups, in pairs, or individually. It can be a quick practice activity or even a formative assessment. The possibilities are endless. However this activity is used, students will practice and gain competence in identifying equivalent and non-equivalent ratios.
