Lesson objective: Solve measurement problems using different systems of measurement.

This lesson provides an opportunity for students to apply their knowledge and understanding of measurement to a real-life situation. Students are asked to determine whether their height allows them to go on a ride at an amusement park, as well as evaluate the heights of others.

Key Concept students will use:

- different systems of measurement for measuring length, and understand that each system includes different units.

Skills students will use:

- aligning the length unit and the measured object correctly (Grade 1, Unit 16).

Students engage in Mathematical Practice 6 (Attend to precision) as they measure given heights and explore the metric and customary measurement systems.
