3 Act Tasks

We were inspired by Dan Meyer’s 3-Act lessons and wanted to create a series of 3-Acts for Elementary Mathematics (and some for Middle School)!  Please share your comments and let us know if you try one (or more).  We’d love the feedback!  Thanks in advance!

The link below will take you to the tasks that we (Graham Fletcher Jenise Sexton, and I) have created along with the help and inspiration of many others!  Please feel free to share any of your ideas, tasks and comments!
