53. For an upcoming unit, a second-grade SEI teacher will lead students in setting up and running a classroom "healthy snack bar" with donated supplies. Once a week for five weeks, families of students will be invited to the lunchtime snack bar, where students will design menus, take orders, serve food and beverages, ring up purchases at a cash register, and make change. Students will also tell families about their jobs at the snack bar and how they work together during setup.
