Take them to the zoo or park.  Let them run around until they are worn out.  Make sure they're more tired than you.  Get yourself a cold drink and watch them.

When they have stopped flying,let them start jumping.........trampolines are good.

Chalk on the side walk (wet chalk is great) Anything with a ball. Catch, bounce, roll. Get some music on maybe they'll march, sprinklers, buckets and boats, food, popsickles!, get a box for sand (a sand table or water table is invaluable) They'll play for a long time in the wet. Sing, read rhythmical poetry, tickle their toes, tickle there nose, let them tear newspaper and then crumple it and throw their crumple ball in a wastepaper basket  ,,,,,
