This would be a new activity, similar set up to matching pairs, but here we have a square(or rectangle) divided into pieces. The square is like the slide or draw-it 'board' (so we can add background, shapes, text, but then there's an option of creating a grid to divide it: e.g. 3x3, 6x6... then the students get the jumbled up slide (or board) and have to drag&drop to put them together. It's like puzzles but without weird shapes. What do you think?
