Internal Clock: Jog and Nail 30 Seconds

In pairs, one student moves and stops when they think an exact amount of time has passed while the partner times it. It warms up the body and trains the focus a tournament timekeeper needs.

How to play

  1. Free jog; on the signal, everyone jogs until they think 15 seconds have passed and stops; the teacher calls out the real time (2 min).
  2. Pairs with one cone: one moves around the cone however the partner says (side shuffle, skipping, butt kicks) and stops at what they think is 30 seconds; the partner times it and gives the difference (3 min).
  3. Switch roles with new movements (3 min).
  4. Final challenge: the pair moves together at different paces (one jogs, one speed-walks) and tries to stop at the same moment at 20 seconds; it counts if they're within one second (2 min).

Teacher tip

Short on stopwatches? One student can time two runners, or students can use their own digital watches. Point out that a tournament timekeeper loses track when they get caught up watching the game; that's exactly what this trains.
