EUREKA MATH2

Students infer a mathematical problem from a video. Play the Drinking Enough? video. If necessary, replay the video and ask students to note any details. Give students 1 minute to turn and talk about what they noticed. Engage students in a brief conversation about the video. Discuss student observations and any relevant questions they have. Guide the conversation to thinking about how much liquid the person in the video drinks in 1 day. Consider asking students the following possible sequence of questions. What do you notice? The article suggests people should drink 3 liters of liquid each day. The person drinks many times during the day. The person drinks different kinds of liquid throughout the day. What do you wonder? I wonder how much liquid is in each container. I wonder how much the person drinks in total during the day. I wonder whether the person drinks 3 liters in a day. What do we need to know to determine whether a person drinks 3 liters of liquid in 1 day? We need to know the number of containers the person drinks from during the day. We need to know the liquid volume in each container the person drinks. We need to know whether the person drinks all the liquid that was in the container each time. Invite students to turn and talk about benchmark amounts or real-life objects that can help them think about and visualize how much 3 liters is. Transition to the next segment by framing the work. Today, we will determine whether various people drink 3 liters of liquid in a day and compare our strategies for finding their totals. 466
