I designed these cards with Starter kids in mind but I think they can work just fine with Movers as well. I use them with early finishers. If they finished the task they were working on, they pick a card from the deck and do what it says on it (all the activities on these cards are writing activities).
Just print them on card, cut around the dotted line, put them in a deck and keep them in the classroom. Download them here: EarlyFinishers.
Hope they help!
