GRADE 8 » EXPRESSIONS & EQUATIONS UNDERSTAND THE CONNECTIONS BETWEEN PROPORTIONAL RELATIONSHIPS, LINES, AND LINEAR EQUATIONS. » 5

Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways. For example, compare a distance-time graph to a distance-time equation to determine which of two moving objects has greater speed.

Graphing : Distance vs TimeTeacher Name: Mrs. Neville

Student Name:     ________________________________________

CATEGORY 4 3 2 1 Type of Graph Chosen

Graph fits the data well and makes it easy to interpret.

Graph is adequate and does not distort the data, but interpretation of the data is somewhat difficult.

Graph distorts the data somewhat and interpretation of the data is somewhat difficult.

Graph seriously distorts the data making interpretation almost impossible.

Labeling of X axis

The X axis has a clear, neat label that describes the units used for the independent variable (e.g, days, months, participants' names).

The X axis has a clear label that describes the units used for the independent variable.

The X axis has a label.

The X axis is not labeled.

Labeling of Y axis

The Y axis has a clear, neat label that describes the units and the dependent variable (e.g, % of dogfood eaten; degree of satisfaction).

The Y axis has a clear label that describes the units and the dependent variable (e.g, % of dogfood eaten; degree of satisfaction).

The Y axis has a label.

The Y axis is not labeled.

Neatness and Attractiveness

Exceptionally well designed, neat, and attractive. Colors that go well together are used to make the graph more readable. A ruler and graph paper (or graphing computer program) are used.

Neat and relatively attractive. A ruler and graph paper (or graphing computer program) are used to make the graph more readable.

Lines are neatly drawn but the graph appears quite plain.

Appears messy and "thrown together" in a hurry. Lines are visibly crooked.

Accuracy of Plot

All points are plotted correctly and are easy to see. A ruler is used to neatly connect the points or make the bars, if not using a computerized graphing program.

All points are plotted correctly and are easy to see.

All points are plotted correctly.

Points are not plotted correctly OR extra points were included.
