2.3+Day+3+Lewes+to+Chincoteague+10-11

Mon.27/Sep./2010 MMEvG Observation and description of changes in the world around us are the first steps in finding and learning about patterns. What are some situations that we can describe as variables? **2.3 Lewes to Chincoteague Island.** New vocabulary.
 * 1) Coordinate pair: The 2 numbers used to find a point on the graph.
 * 2) Equation/Formula: A rule that you apply to certain situations.
 * 3) Pattern: Something that keeps happening and gets predictable.
 * 4) Symbolic form: Anything that is written in Mathematical symbols.
 * 5) scale: a range on each of the axes.

A few Examples from the white board.


 * 1) D=SxT
 * 2) Distance= Speed/Rate x Time = A pattern

Problem 2.3&F.U.


 * A. WOULD IT MAKE SENSE TO CONNECT THE DOTS ON THIS GRAPH? EXPLAIN.**

Answer: Yes, you might be able to find even the tiniest patterns.


 * B. MAKE A TABLE OF (TIME, DISTANCE) DATA FROM THE INFORMATION IN THE GRAPH.**

Answer:
 * Time || Distance ||
 * 0 || 0 ||
 * .5 || 7 ||
 * 1 || 13 ||
 * 1.5 || 22 ||
 * 2 || 22 ||
 * 2.5 || 30 ||
 * 3 || 22 ||
 * 3.5 || 31 ||
 * 4 || 36 ||
 * 4.5 || 47 ||
 * 5 || 47 ||
 * 5.5 || 56 ||
 * 6 || 62 ||
 * 6.5 || 72 ||
 * 7 || 74 ||
 * 7.5 || 81 ||


 * C. WHAT DO YOU THINK HAPPENED BETWEEN HOURS2 AND 4? 1.5 AND 2?**

Answer: Mabye they rode into the wrong street or made a huge curve. Mabye they made a pit stop.


 * D. WHICH METHOD OF DISPLAYING THE (TIME,DISTANCE) DATA HELPS YOU SEE THE CHANGES BETTER? A TABLE OR A GRAPH? EXPLAIN YOUR CHOICE.**

Answer: A graph, since you might be able see the changes in patterns by measuring the angle of the line.
