What’s a 3 Act task? This visual performance task was originally formulated by Dan Meyer, a former high school teacher who believed that students needed a story to put the math in context.  He structured the 3 Act task.   First, there’s a video/picture that introduces a 
problem (Act 1). Next, there’s a few clues that give a little more context to the problem (Act 2). Usually, I expect the students to ask for this information.  Students then have
 to construct/craft a solution path themselves. Last is the big reveal–the answer (Act 3).
