Here's the idea :
- Act 1 - "Introduce the central conflict of your story/task clearly, visually, viscerally, using as few words as possible." (check his site for examples)
- Act 2 - "The protagonist/student overcomes obstacles, looks for resources, and develops new tools."
- Act 3 - "Resolve the conflict and set up a sequel/extension."
Here is an Example - The Slow Forty
(eMINTS teachers....seeing any connections to the Instructional Procedures unit expectation?)
Check out Dan's Three Act Math Tasks Spreadsheet and his 3-part blog series with videos and instructions.
This blog post is from 2011, but Dan is not a one hit wonder. I encourage you to explore his recent blog posts and see what he's been up to....hint hint - he is quite an active presenter and does so much more than Three-Act Math Stories.
