Basic Algebra and Computers: Spreadsheets, Charts, and Simple Line Graphs

This activity helps young mathematicians connect the graph and the point-slope form of a line, by first solving a real-world problem and then using that example to motivate the understanding of the equation. By manipulating the gizmo,...

There is more than one way to represent data! Learners explore ways to represent data. They examine stacked graphs, histograms, and line plots. They conduct surveys and use stacked graphs, histograms, or line plots to chart the data they...

Graphs are excellent tools for visualizing data. Use this video to demonstrate what inequalities look like on a number line. Sal draws a number line and shows the inequality. He effectively employs differentiated colors to express the...

Sal trades his tablet for an Excel spreadsheet in this video, which covers fitting data to a line. Using a word problem about median income, he not only solves the problem but also demonstrates how to use scatter plots and Excel tools in...

Young scholars participate in graphing data.  In this graphing data lesson, students make a stem and leaf plot of their summer activities.  Young scholars create numerous graphs on poster boards.  Students discuss the...

Derive tangent lines through derivatives. Scholars use an app to graph functions and investigate derivatives and tangent lines. The interactive automatically graphs a tangent line at a specified point and can also produce tables of values.

Connect the points to create a function. Using points given by the applet, pupils try to connect them to create a line that would pass the vertical line test. The resource keeps track of the number of sets the learner is able to identify...

Sixth graders review the different types of graphs (bar, line, pictograph) They predict the data set they can garner several boxes of conversation hearts. Students record their data using an Excel spreadsheet. They create a graph based...

How many yellow Skittles® come in a fun-size package? Use candy color data to construct a bar graph and a pie chart. Pupils analyze bar graphs of real-life data on the Texas and Massachusetts populations. As an assessment at the end...

What's the difference between frequency and cumulative frequency? Young scholars consider the question as they create a cumulative frequency graph. They watch as the frequency totals grow to create a new shape of the graph.
