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.
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
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?"

"You may want to use bingo chips as counters instead of using paper
models. I also use golf tees instead of cups. Both manipulatives
are inexpensive, more durable, easy to store, and take less set-up
2-3: Mark F., Teacher
Mulica Hill, NJ
"When adding and subtracting integers or decimals, we include an
activity that deals with making a budget or running a company. Students
practice their mathematical skills and experience the idea of what
accounting is all about."
2-10: Sandy H., Teacher
"I allow my students to play Battleship. Each player graphs 3 battleships,
3 destroyers, and 3 PT boats. Each pair of players takes turns calling
out coordinates to sink the ships."
4-1: Mary Jo D., Math Instructor
St. Francis, MN
"I like to have my students create a survey to measure the characteristics
of the average 8th grader. We mail them out to other schools and
then use spreadsheet software to analyze the results and make graphs."
4-7: Robert A., Teacher
"I generate class surveys using a spreadsheet format. Students answer
questions regarding their height, number of pets, siblings, shoe
size, wingspan, and so on. We then learn to use a graphing calculator
to enter the data and create histograms, scatter plots, and box-and-whisker
plots to explore the data and examine relationships."
5-2: Clare P., Teacher
"If a computer is available, students can use software like The
Geometric Supposer: Triangles or LOGO for more practice in classifying
triangles. Working in pairs, one students creates a triangle while
the other classifies it and justifies their answer. Then they switch

"If students have difficulty tracing (paper too thick to see through),
they can use small mirrors to establish the location of each line
6-1: Susan S., Teacher
Belle Plaine, MN
"I really like to have students use the Sieve of Eratosthenes to
find prime numbers and discover divisibility patterns in numbers.
I have students use different colors and shapes to denote divisibility
6-2: Janine L., Teacher
"To introduce prime and composite numbers, I use color tiles arranged
in rectangles. If they can be arranged in more than one way to form
a rectangle, then they are composite. Remind students that squares
are also rectangles. You can also use grid paper to do this activity
if color tiles are not available."
8-7: Cindy H., Teacher
"I have students create a unique shape using pattern blocks. They
draw a scale figure of the shape on an index card and include step-by-step
instructions on how to make the shape on the back of the card. Students
exchange cards and try to build the figure from the instructions."
8-8: Lorraine J., Teacher
"Lay a mirror on the ground between the school and a student so
he or she can see the top of the school in the mirror. Have others
measure the distances from the mirror to the school and to the student,
and from the student's eyes to his or her feet. Have them set up
a proportion to find the school's height."
11-2: Steve W., Teacher
"I have my students use straws and trash bag ties to create three-dimensional
geometric figures. They also use magazine pictures to create a pictorial
geometry handbook that gives real-world examples of the geometry
