This is a great activity to practice using the 24 hour clock. Students use whiteboards and clock manipulatives (I have my students make clocks from paper plates and brads (paper fasteners), which we use throughout the time unit.
Students have the answers to each problem, so they can verify if their partners are correct. Great independent partner activity!
After doing this activity as well as my TV guide activity, students get military (24-hour) time down!
