Social ThinkingÂ® teaches that problems and reactions come in different sizes. Big problems are really serious ones. When we have a big reaction to a big problem, thatâ€™s expected. Medium problems are things we didnâ€™t expect to happen and canâ€™t be quickly fixed. mall problems, or glitches, are ones we can quickly fix on our own if we stay calm. Small problems are â€śno big deal.â€ť However, when our reactions are larger than the size of the problem this can create a whole new problem. The Size of My Problem poster can be used to teach students to develop their awareness of this concept; it can also be used on the spot to help individuals figure out the size of a problem, their reaction size, and then visually see the relationship between them. The bottom of the poster provides some brief instructions to encourage adults to explore with children whether or not their reaction created a new problem. 18" x 24"
