The Real Number Line Are you positive about the negatives?

Comparing People’s Heights GIRLSBOYS If you lined up all the students in my class on this line with the shortest students near the vertical line, what would you notice?

Real Number Line In math, we can use both vertical and horizontal number lines. A real life example of a vertical number line is the thermometer.Show how integers can be graphed on both types of number lines by graphing –2, 0, and 3

Can you compare numbers using two different ways? Graph –4 and –5 on the number line. Now write the comparisons using

Ordering Real Numbers What if the numbers they give are not the same kind? Example: Write –2, 0.4, 0, -1.5, ½, and in decreasing order Now try again with these numbers: 4.6, 0.7, 85%, -1/3, -0.35, 0
