Students will be able to measure length using standard and non-standard units.
Students will be able to describe the steps to measure length using centimeter cubes with visual and partner support.
Tell students that you have a friend named Jimmy who loves amusement parks. Show a picture of a rollercoaster, and ask students if they have ever been to an amusement park or fair. Tell them to turn and talk to a partner to describe a favorite ride.
Explain that Jimmy wants to go to the amusement park and ride the rollercoaster, but he read that he must be at least one meter tall to go on the rollercoaster. Ask students how Jimmy can figure out whether or not he will be allowed to go on the rollercoaster.
Students should respond that Jimmy must measure himself to know whether or not he is tall enough.
Show students a meter stick and/or one meter length of measuring tape. Think aloud, "If Jimmy is taller than one meter he can go on the ride. If Jimmy is shorter than one meter he can not go to the amusement park because he is not tall enough to go on the ride."
