Homework from April 30th - Mrs. Spence

On Thursday, we started chapter 5 by looking at relations and different ways that relations are expressed. We also learned about domain and range and how to properly write them. Homework for Monday is p214 #1-16. Don't forget to finish your Creative Graphing Assignment since it is due on Monday as well!

Creative Graphing Assignment

This was the assignment as written on the board in class. Click on the image to enlarge it.

Basically, you are to create a set of directions that will be given to junior high students to practice plotting points properly. If they do and your directions (points) are accurate, they should reproduce your drawing. In the process of doing this assignment, you will get lots of practice reading points on a graph - something that I've found that a number of students have difficulty doing (at least in the past).

Sample directions:

Plot the following points and join them in order. (3,6), (9, 1),
(-2, 5)...

If you have more than one item in the drawing (ex. a window in a house or an eye of a puppy), separate the sets of points with another set of directions.

ex. Now join the following points...

To Hand In:

- the grid paper with your drawing on it (points indicated)

- a separate sheet with the directions on it (including all points)

If you have any questions, e-mail me!
