Hang the posters around the room and allow students to start at any poster. Have your students write down the candy variety of the poster they start at in the 12 o'clock box on their candy answer sheet. They solve the problem, then move around the room looking for their solution. They continue following the same steps until they've made it back to their original candy variety poster. If they find that they are going back to the same candy variety before making it to all 12 posters they will need to go back and check their answers.
This activity allows students the opportunity to develop their skills of converting between fractions and decimals (include proportional reasoning).
