For PE today, try some Joe Wicks activities. Read the cards and follow the video for examples on how to complete the exercises.
If this won't work, try your own session of PE. If there is still any snow left, can you go sledging? Build a snowman as this requires a lot of muscles! Can you make up a snow dance? Do you have any after school club activities you need to complete - e.g. football skills / gymnastics / dance, etc?
