Numbervator. How to order a set of fractions by converting them to fractions with a common denominator and position them on a number line. The twentieths are reduced to their simplest form by cancelling out common factors in the numerator and denominator.

This clip could be used to reinforce how to convert fractions for the purpose of ordering. Students could write down their own fraction within a given range on a whiteboard. They could then walk around the room and on the teacher’s command find a partner or small group. Students could then work together to convert their fractions and arrange themselves in order.
