PreSlope

These activities develop familiarity with the property of slope. Ask your teacher to review your answers as soon as you're done and before you close.

Order of steepness

Organize these line segments in order of steepness from left to right. Steepest (most vertical) on the left, least steep (least vertical) on the right. The length of the line segment does not change how steep it is.

Match the Diagram

Use the line segment tool to construct an identical copy of the blue drawing. The first two lines are drawn for you. Remember that to draw a diagonal line accurately, it is helpful to count 'along and up'.

Match the star

Use the line segment tool to construct an identical copy of the star. One line has been drawn for you.

Match the Cuboid

Use the line segment tool to construct an identical copy of this cuboid.

Fish Skeleton

Here are two blue line segments. The top line segment has slope = 1 The lower line segment has slope = -1. Match the green to the blue in length and slope. Make the upper green line segments have slope =1. Make the lower green line segments have slope = -1.

Match the slope and length

In this applet there are several blue line segments. Match (same length, same slope) each blue line segment with one green line segment.

Slope has a number

The upper line segments in the previous applet have slopes equal to 5, 4, 3, 2, 1 and -0.5. The lower line segments have slopes equal to -5, -4, -3, -2, -1, and 0.5.

The first applet shows 6 line segments. All the line segments have different slopes. What are the slopes represented in the line segments on the first applet?

Select all that apply

A
8, 5, 3, 1, 0.5, 0.25
B
10, 6, 4, 2, 1, -4
C
10, 6, 4, 2, 1, 0.25
D
8, 6, 4, 3, 1, 0.5

Stick Person

Create a stick person with the line segments given. The number on each line segment shows the slope of the line segment. Moving the points changes the slope. Bonus if your person can floss.

How many line segments in your design have positive slope? How many line segments have a negative slope? How many line segments have a zero slope? How many line segments are perfectly vertical? (this is considered 'infinite' slope or 'undefined' slope).
