Do you have a piece of rope in the garage or a skipping rope? Your child could use this time to learn to skip. They could try both the single jump or the jump then bounce technique.
Get outside and spend some time with your child on their bike, roller blades, skateboard or scooter. Is there something they need help with? You could even set up some jumps with dirt, ply wood or other bits and pieces from around home.
Set up an obstacle course for your child to work on. You may want to include some form of balance item, jumping item, or crawling item to get their brain working by using all of their body.
