Introduction to Linear Functions

Keep your mathematicians engaged using this group linear functions activity. Each of ten groups receives two graphs with both an image and equation, as well as a "who has" phrase to call out the next graph. Scholars stay on their toes as...

Introduce your algebra learners to linear and quadratic functions. Learners compare the differences and relate them back to the equations and graphs. Lead your class to discussions on the properties of a function or a constant slope...

Here is a well-designed resource that provides five yes-or-no questions which model different situations with linear functions. It makes a good pre-test for the beginning of the unit. The purpose is to elicit common misconceptions of...

After defining intercept, Sal solves a simple equation to identify each intercept and then plots the line on a graph. This video would quite nicely complement an introductory lesson on graphing.

Viewers play a game with Sal, in which he presents three different data sets that come from either linear, quadratic, or exponential functions. In solving this puzzle, Sal manages to not only provide a strong definition of each function,...

It's a straight line to understanding how to graph linear functions. Scholars watch an informative video to learn the process of graphing linear functions. They understand how to make and fill in a table of values and then plot the...

In this video, we create an equation and graph to show a linear relationship based on the word problem. This is a good example for algebra and pre-algebra learners to help them understand creating equations and graphing relationships...

Middle schoolers describe plotting functions on the Cartesian coordinate plane. They solve functions on paper and using an online tool to plot points on a Cartesian coordinate plane creating lines and parabolas.

Students investigate linear functions with negative and fractional slopes.  In this linear functions with negative and fractional slopes instructional activity, students match a linear equation or chart of values with the...

In a linear equation, the y-intercept is really just the point where the graph of the line crosses the y-axis.
