Quick and easy task cards to review your unit on Matter, changes, atoms, elements, compounds, and the periodic table. Colorful images with response sheet.I like to do this what I call "scavenger hunt" style and I place the cards randomly throughout the room (on windows, bookshelves, computers, desks). I give students a certain amount of time and have them try to answer as many questions as they can in that given amount of time. It gets them moving and answering questions, preparing for tests!
