Return to the term on the board and student comments. Have students identify which, if any, ideas identified what a ratio is. Guide pupils in defining the term. Divide class into groups. Direct each group to make a series of six peanut butter and jelly sandwiches, each containing a different ratio of the given spreads.
Pupils are to label each ratio.
Cut each sandwich into pieces. Conduct a taste test of the preferred ratio. Have each student within the group taste each sandwich and rate it on a scale of one to six. 4. Direct pupils to graph and report the results of the trial individually, and then for the group. Have each group share their charts with the rest of the class.
