Required Materials
Materials to Gather
Required Preparation
 Each student needs both the Hour Clock Cards and Half Hour Clock Cards from previous lessons.
Launch
 Groups of 2
 Give each student their clock cards from previous lessons.
 “From your pile of cards, take out 12:00, 12:30, 6:00, 6:30.”
 Display these clocks.
 “How are these clocks the same and different?” (They have hour and minute hands. They have arrows pointing to 12 or 6.)
 “What time does each clock show? How do you know?” (12:00, 12:30, 6:00, 6:30. I look at where the hour hand points and then see if it’s ‘o’clock’ or ‘halfpast’ based on the minute hand.)
 “You are going to play a game with your partner using all your cards. Hold up a clock card for your partner and cover up the written time. Your partner reads the time and you check what they say with the time on the card. Then switch roles.”

 Invite previously identified students to share.
 “Why do you think Priya got mixed up? What could you say to help her revise her thinking?” (Priya mixed up the minute and hour hands. I could remind her that the short hand is the hour and the long hand is the minute. I could remind her that if it was 12:30 the hour hand would have to be between two numbers.)
 “On the blank clock, draw hands to show 12:30.”
