1. HOMEWORK: Page 76 (handout) Questions 1 and 2
2. Page 37 Problem 3.1
OBJECTIVE: •To change the form of representation of data from tables to graphs and vice versa •To search for patterns of change •To describe situations that change in predictable ways with rules in words for predicting the change •To compare forms of representation of data [1.5.4, 1.5.1, 1.4.5, 4.2.2] ACTIVITIES/ASSESSMENT: Page 37 problme 3.1. make a table and graph for each store. Do follow-Up on page 38 #2-4. NOTES: Copy the graph and table in the book and construct a complimentary graph and table for the missing part. HOMEWORK: Page 42 #3

9-30-2005 Math 2a
1. HOMEWORK: Integer addition worksheet.
2. dot-to-dot picture and coordinates
OBJECTIVE: See 9-26 above. Integer subtraction [1.1.6] [1.3.3 Understand the location of points on a coordinate grid in any of the four quadrants; Identify the coordinates of the fourth point to make a rectangle given three points. [RL]; Plot and label ordered pairs in any of the four quadrants. [CU]; Name the coordinates of a given point in any of the four quadrants; Identify objects or the location of objects on a coordinate grid using coordinates or labels.] ACTIVITIES/ASSESSMENT: Introduce/review integer subtraction and 4 quadrant graphing. Students will start on their dot-to-dot picture NOTES: HOMEWORK: Dot-to-Dot with a coordinates list on separate sheet.
Remember, some points in each QUADRANT, The assignment is to make a list of the coordinates in order on a separate sheet of paper.[
[
The guidelines for the dot-to-dot picture: Set up a piece of 1/4 inch square graph paper with an x and y axis in the center.
- 1. Must have points in all 4 quadrants
- 2. Minimum of 30 points
- 3. Points must be in order and numbered. You cannot pick up the pencil and move to another place.
- 4. Lines MUST change direction at a point (i.e., a staight line only has points at the end - no intermediary points)
- 5. Retracing a line is allowed, but remember the line must change directions at a point.
The picture must be something recognizeable. Some exclusions include:
- no logos
- no letters, initials, words
- no robots or space aliens
- no Christmas trees
- no designs
Some acceptable designs might be vehicles, buildings, plants, animals, people and cartoon type characters.
Here are some point for a dot-to-dot picture in all 4 quadrants. You can either plot them on graph paper or plug them (cut and paste) into the tool on the left margin above (online plotter)( The numbers go down the columns... )
