Language Objective

By the end of the lesson, I will be able to use
the four language domains of listening, speaking,
reading and writing to communicate the
academic math language of positive and negative
integers on a number line.
I will be able to place positive and negative numbers on a
horizontal and vertical number line.
 Academic Math language Vocabulary: integers, positive,
number line, gain, deposit, credit, receive, loss, debit,
negative,charge, below zero, owe, withdraw.

Opening Problem
On your white board please draw
horizontal and vertical number lines.
 Try and place these numbers on both
number lines:


-3

Let’s try some examples
On your white board draw horizontal and
vertical number lines.
 First we are just going to work on placing
positive and negative numbers on the
number line.

-4

and their
opposites

Now you try some examples

On your white board draw horizontal and
vertical number lines.
◦ Graph each point and its opposite on
the number line.
◦ Explain how you found the opposite of
each point
◦ What does each tick mark represent?
-2, 4 and 6

topic.
Here’s another one…
On your white board draw a horizontal
number line.
1. Choose an integer between -5 and -10.
Label it R
2. What is the opposite of R? Label it Q
3. State a positive integer greater than Q,
label it T.
4. State a negative integer greater than
R, label it S.
5. State a negative integer less than R.
Label it U.

Think about it…

Carlos uses a vertical number line to graph
the points -4, -2, 3, and 4. He notices that -4
is closer to zero than -2. He is not sure
about his diagram. Use what you know
about a vertical number line to determine if
Carlos made a mistake or not. (support
your explanation with a number line
diagram).

Open your packet to page 5. Write each individual
description as an integer and model the integer on
the number line using an appropriate scale.
Now
