Monthly book order forums offer a wealth of learning experiences. One thing students can learn is reading decimals correctly in the context of money. Allow the students to discuss the books they like for a few minutes. Guide them in reading how much the various items cost. Students seem to pick this up quickly, because it is presented in a real life situation. I also teach estimation at this time. Most of the prices end in 95 cents. Show them that the price is actually closer to the next dollar amount.
