First-Then boards work nicely for helping children to transition from one activity to the next. I created this particular horizontal board to provide repetition of moving from left to right (pre-literacy) and to save on ink. The First-Then boards I encountered were all red and green verticals and used a significant amount of ink. Print on cardstock. Laminate the board. Put a small piece of velcro in the middle of both boards and the back of the board. Store the commonly used pics on the back of the board.
