What suggestion can you offer for enhancing a specific lesson of a Glencoe mathematics text? Ideas may include using concrete objects to illustrate concepts, working with cooperative groups, incorporating ongoing assessment, or any other strategy that you have used successfully in your classroom.

Example: This activity was written by a teacher using the 2001 edition of Glencoe Mathematics: Applications and Connections, Course 2, lesson 6-1, page 228. The lesson is entitled "Solving Addition and Subtraction Equations."

"To reinforce the Addition and Subtraction Properties of Equality, I use the example of a teeter-totter. You and a friend are perfectly balanced on a teeter-tooter. What happens if your friend jumps off? Or what happens if someone else jumps on with your friend?"

"I compare absolute value inequalities to the amount of gas in the tank of a student's truck and the direction the student can travel (left or right) out of the driveway. For example, if they have $5 worth of gas, they can drive a certain distance wither way until the gas is gone (that is, |x| = 5). If they have more than $5 worth, they can drive farther either way (|x| > 5)."
