Recently, the teachers at MIS watched a TedTalk by Dan Meyer on teaching mathematics: Math Class Needs a Makeover.
He has developed a model that he uses with students in Grades 5-12; however, it could be adapted to the younger grades. He calls it the Three-Acts of a Mathematical Story.
Act 1: Engage all and lower barriers to entry.
Present a visual that pushes students to question, wonder, and has very few words. It should be something that connects to the students and will engage them in mathematical thinking that they might not have thought of before. Students are asked to pose questions based on these visuals. Watch this Act 1 using what we all love to pop: Bubblewrap, and allow your brain to wonder.
- Guess how long the other bubble wrap pieces will take to pop.
- Give an answer you know is too high.
- Give an answer you know is too low.
- What information would be useful to know here?
- What information doesn’t matter?
- Look to the primary sources for answers and ask for guesses first.
Show the students the answers. Show the same visual but now with the answer. Ask students to see if their questions were answered. Whose answers were the closest? How did they guess? Allow time for discussion and reflection. Here are the videos below revealing the answers to the large and medium sheets of bubblewrap:
Where can we find more examples like this for Junior School students where students can engage in authentic, real-life inquiry? And, can we make our own?
