This motivating bookmark is designed for celebrations and reading rewards, with an added bonus message: make a difference by living green. It comes in a pack of 30 bookmarks, so every student can learn about taking care of the environment while reading various books. "These bookmarks not only promote an eco-friendly lifestyle, but are made with 20 to 28-percent post-consumer waste material," Creative Teaching Press Marketing Specialist Lauren Tuculescu told TDmonthly.
