My co-teacher and I are working with our enrichment group (Success period for those of you who follow the 8-step protocols) on probability this week. We’ve been able to bring in a lot of engagement activities for the students through this unit.
– We’ve used M&M fun-size bags to take data and study probability of certain colors being in a bag.
– We’ve taken data and based on that data, created rules to reverse engineer what happens in an M&M plant: what the rules are for bag assembly.
– Students are gaining practice entering data into Excel, and creating bar and pie graphs for this data. They have some stringent requirements to refine the graph so the colors of the pie match the colors of the M&M’s, and also we are focusing on labeling.
In the reverse engineering study with a sample size of 18 bags, we’ve discovered that:
(1) Two M&M’s out of every bag must be green.
(2) There are never just one color of M&M’s in a bag.
(3) The number of M&M’s in a fun-size bag varies from 13 to 21. (Wow.)
(4) The only colors that will definitely be in every bag are red and orange.
