    Like you, I love Ryan’s idea about beginning with a visual of a carton (or a glass much like your Hot Chocolate video) and a liter of milk and asking the students to Notice and Wonder. Write down their observations. And then provide another video or visual of actual pouring of the milk into a glass. Then estimating how many glasses of milk they think the liter can fill. (For multiple entry points students could determine the amount of milk in each glass (250ml) requiring measurement conversion. Visual drawing could be made to represent 4 glasses per liter and multiplicative thinking. Act two, would proceed as Ryan indicated with the pouring of the liter into the jug. Estimating how many liters will fill the jug. And wondering how many glasses could be filled from a jug. Here is where the double number line would be valuable as the next step of representation. (top line marking liters, and bottom line marking cups (1:4). Act three would show the six jugs being poured into one container alongside a carton (=250ml/glass). A composed unit ratio table would be appropriate:
