Or so Dan Meyer suggests.
Check out his TEDx talk on how we can help our students better learn mathematics, by being purposely less helpful. I have started to integrate problems like this in my own G7 classroom, and have found that it has increased engagement, collaboration, and inquiry amongst students.
Dan also has tons of great ideas to use in your own classroom. I highly recommend Dan Meyer’s 3 Acts: Incredible Shrinking Dollar; Shower vs Bath?; A Lousy Mathematical Problem, especially Graphing Stories!
