Hi KittyKatty,
Why not start with a warm-up game like Beans and then move onto some skills.
I like to let the children have some time for free exploration of 'PE' equipment - beanbags, balls, frisbees, ropes, stilts, hoops etc. Let them find different ways of using the equipment - it can be very informative and great or assessment purposes.
Then move onto some skills - how about early tennis/badminton skills. First, get the children to balance a beanbag on a bat (bat hold should be like a 'handshake' grasp)...then toss it like a pancake...swap it for a ball and balance again...push the ball around on the floor and stop on command, change direction...pat the ball to each other, firstly using their hands and then, if appropriate, use the bats...
Don't forget to finish with a cool-down activity - I like to get the children to be 'soggy balloons', taking deep breaths to blow themselves up as bog as possible...and then letting all their air out with big raspberry noises as they run around the area bfore sinking to the ground and becoming still.:running:
Have fun!
