Lesson 14: Adding Negative Numbers
Overview Use the calculator to add negative numbers.
Teacher Materials “Adding Negative Numbers”, and “Football Game”
transparencies. “Play Cards” cutouts.
Student Materials Pencil, Calculator, and Score Sheet.
Keys Introduced +/-.
Teaching Notes Remember to explain that numbers can be positive
and negative. Use a number line to illustrate that
numbers to the left of 0 are negative and to the right
are positive. Point out that the +/-. key allows
students to calculate negative numbers.
The purpose of the football exercise is for the
classroom to use their calculator to calculate the
correct position on the field after several plays with
positive and/or negative yardage.
Cut out the “Play Cards” and shuffle.
Use the Football Game transparency to show
the football field.
Mark the 50 yard line on the transparency with
a marker; this is where play will begin.
Call three students to the front of the class and
have each of them select a “Play Card” from
the deck.
Have each of the students read their card one
at a time, while the rest of the classroom writes
the result of each play on their “Score Sheet”.
The 1
st
card read will be marked on the “Score
Sheet” as 1
st
Down, the 2
nd
card will be 2
nd
Down, and the 3
rd
card will be 3
rd
down.
After the all three plays have been read, ask
the classroom to calculate the Total Gain or
Loss of that drive.
Use the football field transparency to mark the
Total Gain or Loss. If a touchdown is scored,
start over at the 50 yard line.
Call up three new students and continue to play
until the score sheet is completed.
