# Roll to Win Investigation – Graphing Classroom Activity

Graphing is an excellent way to display data visually. Students will come in contact with a variety of data and ways to display this data over time. It is important that students understand that there are three main types of graphs used to display information. The three types of graphs are line graphs, pie charts, and bar graphs.

The type of graph you decide to use depends mostly on the type of data you need to display.  Bar graphs are used to compare things between different groups of data or to look at changes over time. Bar graphs can be either horizontal or vertical. Line graphs are also used to compare changes over a block of time for multiple groups of data. The third types of graphs are pie graphs; these graphs best show data that compares parts of a whole.

Students should understand that this mathematics concept is embedded into real-world scenarios everyday.  Data is collected for a multitude of reasons including surveys. Data collection can happen a variety of ways and for a variety of reasons.  For beginners, it is easiest to record survey data by using tally marks. Tally marks can be collected and recorded in a table. This table later becomes what is known as a frequency table. See below.

After the data is collected using tally marks and/or a frequency table, that data can be displayed in a visual graph.

There are two activities attached to this article. The purpose of the first activity is to give students a chance to practice collecting and recording data in a tally chart. The second activity is a practice page for students to answer questions based on the tally charts and bar graphs displayed.
