```Model of Project Given to Students
Comparing
• Create number line first. There are sample number lines in classroom. If
you would like to use one of these please ask for one.
-2
-3/5
-0.2
½ 0.6
• If you count on this number line there are 10 marks from 0 to 1. Because
of this each mark represents 0.1.
• Once number line is created, comparison of numbers is very easy. The
further to the right, the greater the number.
• Two negative numbers: Use any of your two negative numbers to compare
-2 __<__ -0.2
*ALL of this work would go in the Comparing Section of your poster or
electronic presentation.
Absolute Value
• Remember that the absolute value is the distance from zero, and distance can
only be measured in positive values.
Use your 5 rational numbers and show the absolute values of each. Model
yours from the examples below.
−2 = 2
−0.2 = 0.2
1
1
=
2
2
The distance from -2 to zero is 2 units.
Number Problems
• Read the directions carefully. They describe exactly how the
problems should be set up. Remember “like signs” means problems
where both numbers are positive or both are negative and “different
signs” or “unlike signs” means that one number is positive and one
number negative.
• You may use any of your 5 numbers as long as you match the
directions. You may use each more than once.
• I would suggest making blanks and filling them in.
____ + _____ =
____ + _____ =
