This is based on that kids toy that has the twist/pull/turn/bop buttons, on which the kids must complete ever more complicated patterns.
To start, create some easy word/movement associations, and practice as a class. For example, when you say “Bop it,” the kids must touch the floor with 2 hands. When you say “Jump it,” the kids must jump up in the air. When you say “Punch it,” the kids must punch 4 times in quick succession in front of them…etc.
You can play this game with eliminations or not.
Now, give the kids a pattern (i.e. Bop it, Bop it, Jump it, Punch it), and see who can do it. Add movements, and ever increasing difficulty levels, to keep the kids moving.
Have the kids make up their own “Bop Its,” and try and teach the class.
