3 Act Math Task Sugar Cubes

During a warm up in 5/6 math last week, we were solving a problem about the sugar in Mountain Dew.  This led us to a conversation about sugar cubes.  Several students were trying to estimate the weight in grams of a sugar cube.  Inspired by their work, we created this three act math task to solve together.

Act 1

How much do the sugar cubes weigh?  What do you notice?  What do you wonder?  What information would help you solve this problem?

Act 2

Act 3
