In some cases, it is useful to set up a pretzel bank, which accepts and pays out pretzel credits on behalf of non-participants. Usually, after one or two observations, non-participants will rejoin the group and act appropriately. During the first few weeks, focus on positive comments and rewards only. Later, use judgement as to when to allow negative comments and reparations, if at all. Dealing with negative allegations requires considerable teacher expertise.
Some teachers use Pretzels successfully all year long without advancing to negative issues.
Do not use candy or sweet snacks, as these may have unwanted psychological implications. You can, if you wish, eliminate tokens and have children exchange items directly. If using snack items in this manner, do so only if they are individually packaged. For health reason, it s best to avoid exchanging unwrapped food items. In addition, the foundation publishes The Responsive Classroom, a newsletter for teachers, four times a year.
