Big Idea: Observation and description of changes in the world around us are the first steps in finding and learning about patterns.

Essential Question: What are some of the variables around us?

Notes: There is no graph given by Malcom and Sarah. They started the trip at 8:30. It took them 7½ hours to go 80 miles.


 * A. Make a table of (time, distance) data that reasonably fits the information in Malcolm and Sarah’s notes.**


 * || **Day 4 Trip** ||  ||
 * Time || Time (hours) || Distance (miles) ||
 * AM 8:30 || 0 || 0 ||
 * 9:00 || 0.5 || 4 ||
 * 9:30 || 1 || 9 ||
 * 10:00 || 1.5 || 15 ||
 * 10:30 || 2 || 15 ||
 * 11:00 || 2.5 || 18 ||
 * 11:30 || 3 || 20 ||
 * 12:00 || 3.5 || 27 ||
 * 12:30 || 4 || 34 ||
 * 1:00 || 4.5 || 38 ||
 * 1:30 || 5 || 38 ||
 * 2:00 || 5.5 || 38 ||
 * 2:30 || 6 || 38 ||
 * 3:00 || 6.5 || 43 ||
 * 3:30 || 7 || 45 ||
 * 4:00 || 7.5 || 80 ||


 * B. Sketch a coordinate graph that shows the same information.**

Problem 2.4 Follow Up


 * Explain how you used each of the six notes to help you make your table and graph.**

I used the six notes to make my table and graph is that first, I made a table by having 3 columns (time, time (hours) column because they started at 8:30. Then I filled out the whole time (hours) column with starting at 0 and each line increases by 0.5 hours and fill it up to 7.5, because they took 7.5 hours to finish the trip. After finish filling out the time column, I filled out the whole time column by adding 30 minutes to the line before the one I’m about to fill out and the addition goes on the line and keep on doing that until I reach 4:00. Then I fill out the distance (miles) column as much as possible by looking at the notes, then guess the rest of the lines I the distance (miles) column. At about ¼ of the trip they probably had a break so I put no movement at 1.5&2hours. Finally I just copy down the data in the table to a graph by putting the Time (hours 0 column in the x-axis and the distance (miles) in the y-axis and put the dots where they go by looking at the data in the table.
