__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 from class: __ · Pretty much everyone (including myself) thought tables were better than graphs. · For continuous events like time and biking distance, you should connect the coordinates. For discontinuous events, you should not connect coordinates. · What we didn’t discuss was what some examples of discontinuous events are, which confused me. · A new vocabulary word we worked with was Coordinate pairs, which are the pairs for coordinate graphs, which always have x-axis first and then the y-axis.

· Easy to make || · Harder to see progress/no progress · Can’t see distance as good ||

<span style="font-family: 'Comic Sans MS',cursive; font-size: 120%;">· Gives explanations || <span style="font-family: 'Comic Sans MS',cursive; font-size: 120%;">· Doesn’t have key points <span style="font-family: 'Comic Sans MS',cursive; font-size: 120%;">· Harder to see the data so its hard to plot <span style="font-family: 'Comic Sans MS',cursive; font-size: 120%;">· Takes long to write ||

<span style="font-family: 'Comic Sans MS',cursive; font-size: 120%;">Summary: <span style="font-family: 'Comic Sans MS',cursive; font-size: 120%;">For this investigation, we basically discussed the three ways you can show data; graphs, tables and a written report. We dealt with problems that had to do with those three, where we actually got to create our own graphs, tables and written report about certain data. We discussed each of them and talked about why we liked using each of them and why we didn't, so basically the advantages and disadvantages of them. Personally, I like tables better than all three, but that is just my opinion and the other two are still good ways to show information.
