As you can see in the video examples above, a 3-Act Task is a math routine with three parts that we use to practice problem solving in a real-world context:
Act 1
We use a picture or a video to launch the context. Students notice and wonder, generating mathematical observations and questions.
Act 2
We choose one question to solve, students think about what information they need to solve it, and once teachers give them the additional information, they get to work!
Act 3
We share and compare solutions.
