In this engaging interactive whiteboard activity students will practice finding the constant of proportionality in proportional relationships. This activity specifically addresses CCSS.7.RP.A.2.B by having students identify the constant of proportionality (unit rate) in tables, graphs and written descriptions of situations. Each student fills their bingo card with 16 numbers from a set of 36 numbers that correspond with randomly selected proportional reasoning problems. Bingo card and answer key printables included. Your students will enjoy playing this game while learning about proportionality constants unit rates, and proportional equations using real world contexts.
