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 1995 edition of
Mathematics: Applications and Connections, Course 2, lesson
7-4, pages 263-265. The lesson is entitled "Adding Integers."
used students holding a positive or negative sign instead of using
counters. Students took turns in front of the room displaying their
signs. Those at their seats wrote the addition sentence shown by
the human counters. Those remaining after zero pairs sat down represented

"I brought several keyboards to class so students could see, feel,
and hear the difference in quality. Students used catalogues and
play money to purchase a keyboard and any necessary accessories.
The purchase price also included tax."
1/Lesson 2-3a: Nancy B., Teacher
"Students in my class collected data on topics that they selected
and that required making a frequency table. They surveyed classmates
and recorded the data on their frequency tables."
1/Lesson 2-3b: Brenda J., Teacher
"I extended this Mathematics Lab by having our computer lab teacher
demonstrate data base software in the computer lab. Then students
were given an opportunity to complete Exercise 6 and print their

"As an end-of-chapter class project, I give cooperative groups each
a package of Skittles candy. Then I ask students to apply the skills
and concepts learned in this chapter to represent the colors of
the 'average' package of Skittles based on percentage, ratio, and
fraction of color. They were to graph their findings."
1/Lesson 3-2: Dennis G., Teacher
"Cooperative groups are given a number to read and display in front
of the class. Each student must represent a place value or a place
holder by writing the appropriate single digit on a sheet of paper.
A ball is used to represent the decimal point."
1/Lesson 3-10: Linda L., Teacher
"To introduce the concept of perimeter as the distance around a
figure, my students danced the conga around the classroom."
1/Lesson 4-3: Linda G., Teacher
"My students cut out the necessary number of decimal models and
taped them together. This made it easier to model the exercises
like those modeled in their books."

Grand Island, NE
"Students in my class made different shapes using geoboards. They
let the smallest square section enclosed by four pegs equal one
square unit. They then found the area by counting and by using the

"I do the following procedure to show students that the circumference
can be measured with a meterstick. Wrap a piece of nonstretchable
string around a large can, mark the string where it meets the end,
lay it flat on a desk or table top, and measure the length marked
on the string."

St. Charles, MO
"I use a balance scale and pennies to model equations. This allows
students to see that whatever I do to one side of the scale I must
do to the other side to keep the scale level. Then I have students
use the scale themselves for hands-on learning."

Rochester Hills, MI
"You may want to allow students to use the paper plates from the
Mini-Lab on page 253 to illustrate the renaming process used in
subtracting mixed numbers."
1/Lesson 7-8: Granotta H., Teacher
"In my class, we ran a 'time bank' to model renaming units of time.
If students needed change for a 1-hour bill (yellow squares of paper),
the teller would give them 60 minutes (green squares of paper).
If they needed change for a minute, they received 60 seconds (red
square of paper)."
1/Lesson 8-8: Cathy B., Teacher Support Team
"You may want to use the model at the right to show students how
to rename customary units of capacity."
1/Lesson 9-1: Marilyn P., Teacher
"I used pentominoes and tangrams to illustrate many of the concepts
and 'Words to Learn' in this chapter."
