Let your students be the star of the show!!! This word file allows you to just insert your students' names into the problems. You would be amazed at how much this increases their engagement!
This set of worksheets addresses the CCSS standard 6.RP.A.3 but focuses mostly on 3d. It can also be used for 5.MD.A.1. I have included a guided worksheet that uses a step by step method focusing on using ratio and proportions (equivalent fractions) as well as 15 measurement conversion problems for practice. You could also change the content of the questions to your liking.
