3 Act Math lessons are a great way to introduce a unit. It is especially cool when you can create a real need for the math that students are about to learn either by making it possible to find a solution or by making the solution easier to find.

The basic
concept is

Act 1: Show some
sort of media image or video and let kids ask questions. Choose a
question to try to answer.

Act 2: Have kids
tell you what other info they need to answer their question. Research or
provide that information.

Act 3: Reveal the
solution.

The whole process takes quite a while, so you can't do this every day and make it through all of your
content. However, I like to use these on the first day to introduce a new
chapter.
