This FREE lesson helps students to visually see what a ratio is by using a "Pet Shop" Scenario. Here the teacher has the students place various animal pictures into their pretend pet shop. The students have to come up with different ratios based upon what the teacher has given them to find. This is a very fun hands-on group lesson and has helped my students see how to write ratios. It also allows you to have some very open dialougue about how students should be simplifying ratios.
