Football season is coming to an end, and the kids are excited to play! Only the best of the best will make it to the playoffs, and they need all the practice they can get. Unfortunately, the coach locked the ball away and misplaced the key over break. It’s adding up to disaster! Are you on the ball enough to find the key, open the locks, and save the day?

Print one copy of page 6. Use the invisible ink marker to write in the missing digits: 2 on the red, 5 on the green, and 7 on the yellow.
Print multiple copies of page 7 (single-sided, enough for each student to have one) and cut apart.
Print out the envelopes with the directions and scannable QR code with audio directions (or alternately, just print them on sheets of paper to set at the stations) -
2. Set the locks up as follows:
- 4-Letter Lock: PLAY
- 5-Letter Lock: FIRST
- 3-Digit Lock: 777
3. ill the box with discussion cards, prizes, certificate or whatever want to end with. Place the hasp on the box, then attach the 4 locks:
- 4-Letter Lock
- 5-Letter Lock
- 3-Digit Lock
- Keyed lock: tape the key to the door
4. Set up the stations as follows:
4 puzzle pieces, envelope with directions, whiteboard and marker (or paper and pencil), 20 counting objects (blocks, bears, etc)
4 puzzle pieces, envelope with directions, copies of grids, colored pencils (or regular pencils, markers, crayons, etc), 20 counting objects (blocks, bears, etc)

blacklight flashlight, 3 puzzle pieces, envelope with directions, whiteboard and marker (or paper and pencil), 20 counting objects (blocks, bears, etc)
5. Hand out lock trackers and discuss that each blank is a space where students will write in a combination. Show each of the locks on the box and make the connection to where their combinations will be recorded on the lock tracker.
6. Divide the students into small groups and instruct them to move to a station. As groups work together to solve the problems, remind them to record their solutions (combinations) on the lock tracker. Have them rotate to other stations as groups finish.
7. After 45 minutes have elapsed, gather everyone back together, and discuss how they discovered the combinations and what they are. Allow all students (even if they didn’t finish) to fill in the combinations they may have missed.
8. Starting with the group who completed each puzzle first, have groups come up and remove one lock from the hasp:
- Puzzle 1 = 4-Letter Lock
- Puzzle 2 = 5-Letter Lock
- Puzzle 3 = keyed lock (this group will have to go find and remove the lock from the door
- Puzzle 4 = 3-Digit Lock
9. Debrief using the Breakout cards or any other method deemed appropriate for your group(s).
