Sourcing Each curriculum unit contains several integral lessons. Some are based on recommendations from individual teachers and others are complementary, built from teaching units provided by educational promotions from various companies and industries. The cost of an average backpack depends on the nature of the materials in the curriculum unit. The contract explains that children can participate in the program and that parents are expected to help them accomplish the activities. Because of the wide range of achievement levels in any one grade or class, children may find that some materials are simple, some in their comfort zone, and others more difficult.
Parental support is thus critical to each child's success.
It can include reading aloud, listening to reading, explaining directions, and helping with cutting, pasting, coloring, or final assembly of the end product. Parents also agree to be responsible for the proper care of the contents of the unit and to replace lost or damaged pieces. They are asked to write a note in the journal that details their family experience with the activities. The consent agreement also indicates that children are allowed to take the backpacks home on Thursday or Friday and to returned them to the school on Monday. A team of volunteers then replenishes consumable materials such as crayons, glue sticks, pencils, and batteries in time to redistribute the backpacks later that week.
