3-Act Tasks

A 3-Act Task is a group participation exercise articulated in three distinct sections or acts,
using videos and photos. Each task is a rich mathematics exercise worthy of quality classroom discourse and creative problem solving.

The concept was developed by Dan Meyer, who serves on our Advisory Board.
