Someone ate my cake!

StrawberryCake

In this fraction operation and representation activity, students are asked to decide how much of my cake was eaten. Using fraction multiplication (or angle measure if that is where you need an activity) they find out how much someone owes me for what they ate. The task could also solve using ratio and proportion reasoning. Technology: This interactive fraction models app from NCTM Illuminations can be a useful tech tool allowing kids to recreate the left over cake while the application gives students the corresponding fraction.
