In this Read-Along lesson, twins Mimi and Lulu try different ways to catch a mysterious nighttime visitor…until they hit on just the right solution. The lesson includes a short exercise where students imagine how to design a good monster trap, and then pretend to be sneaky monsters. You can extend the lesson with the optional activity, Be an Inventor, where students draw their own inventions for machines that do chores.
No activity prep.
