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 word phases that describe different linear functions. The commentary not only gives an explanation of the solution, but explains how the student may mistake the situation.
In this linear functions worksheet, students solve and complete 10 different types of problems. First, they write the particular equation expressing the number of items represented in each problem. Then, students find the x- and y-intercept and what it represents in the real world. They also plot the graph of a given linear equation.
Learners investigate the relationship between the Fahrenheit and Celsius temperature scales. Given two data points, they construct a linear function to describe the relationship, find the inverse of the function, and make observations about function values in the context of the problem. The exercise is easily adaptable for either instruction or assessment.
Students explore the concept of linear functions. In this linear functions lesson, students translate linear functions from tables to graphs to equations. Students use an applet to write a function rule for a linear function in English, as a table, and in algebraic form.
Students graph linear functions. They plot three points, create a line, and discuss methods to find the slope of line. In groups, students solve problems, graph their lines and find the slope of a line using various methods. Upon completion, students 'decorate' their lives.
Use algebra to solve real world problems. Mathematicians practice use of graphs, tables, and linear functions to solve a problem regarding mp3 purchase plans. They work in groups to solve the problem and present their findings and reasonings upon completion. This lesson plan contains the problem in a printable format.
