Before the school year starts, teachers can find all of the supplies that they need from companies like Staples and Office Depot. Money can be saved while shopping with these retailers by using coupons found on Giving Assistant. In order to get as many supplies as possible, such as pencils, folders, crayons, paper and charts to use in lesson plans, be sure to check for available promo codes. You can also purchase books for students to use in the classroom or to read during free time. Glue sticks and clipboards are other items to complete the supplies in the classroom.
