One large circle is made with cones, with two smaller circles within. Each of these circles count for points (eg. large circle = 3, mid circle = 2, small = 1). Make each circle out of different color cones.
Class is split into approx. 5 teams. Each team lines up behind a Tee, and has one bat and 5 balls.
On the whistle, first person from each team has an attempt at aiming their balls into the circles, and counting their points from where their balls land.
Once all the first people from each teams have hit, the coach blows their whistle again for the batters to run out and collect 5 balls (doesn't have to be theirs). Once the 5 balls are returned, second in line has a turn at batting their 5 balls, and so on until everyone has had a turn.
Make sure that when setting up the tees, no team is directly across the circle from another team - to ensure safety (set up the Tees on the outside of HALF the circle only).
At the end of the session, see who has the most points.
Modification: option to teach batters the "step/stride" with the front foot to generate more power if successful in basic technique.
