Students solve and graph linear equations. In this algebra instructional activity, students collect and plot data on a coordinate plane. They use the CBL and TI calculator to graph systems of equation.
Students create a spreadsheet to analyze functions. In this algebra lesson, students use spreadsheets to find the intersection of systems of equations. They identify the dependent and independent function as it relates to a line.
Ninth graders explore linear inequalities. For this Algebra I lesson, 9th graders investigate one and two-step linear inequalities. Students examine the phrases “at least” and “at most” in a problem solving context.
High schoolers investigate families of functions. In this families of functions instructional activity, students discuss how changing a functions parameters affect its' graph. High schoolers vary slope and y-intercepts of linear functions. Students stretch and shift trigonometric functions.
Students differentiate between exponential growth and decay. In this algebra instructional activity, students solve exponential equations using properties of exponents. They use the Ti calculator to graph and analyze their functions.
Students read real world problems, determine the variables, and set up the function using algebraic statements. After entering data into the graphing calculator, they display information in the form of graphs and scatter plots. Students identify minimum and maximum values.
Young scholars participate in a lesson that reviews the concept of linear functions in connection with preparation for an exam. The teacher reviews problems with the students for scaffolding. Young scholars practice graphing linear functions.
Learners investigate step functions. In this Algebra II/Pre-calculus lesson, students examine various taxi fare schemes and model the fares with step functions by making use of the calculator’s greatest integer function’s step function properties.
Learners solve for the inverse functions. In this algebra lesson, students graph the inverse function and analyze it. They solve and manipulate equations using the calculator.
Students evaluate the area of a picture frame and write algebraic representations. In this algebra lesson, students work in groups to find the area of different picture frames. Students then write algebraic expressions and present then to the class.
Students build fractals. In this math lesson, students examine the patterns of fractal development and describe them using algebra.
Students solve equations and graph their solutions. In this algebra lesson, students identify the domain and range of an equation and a graph. They identify the properties that make a graph a function.
Students solve and graph linear equations. In this algebra lesson, students collect data and plot it to create a linear function. They identify the domain and range of each line.
Pupils manipulate integers quickly to get their answers. In this algebra lesson, students play an interactive game as they review basic algebraic operations. They add, subtract, multiply and divide quickly to get the correct answer.
Learners explore concept of functions as relationships, as machines, as equations, and as graphs.
Students engage in a lesson about rational functions. They solve problems using g(x)/f(x) as the format for the function. The lesson includes sample directions to perform operations with the help of a graphing calculator. The instructions are specific for the Texas Instruments calculator.
In this variables and functions activity, 9th graders solve 8 various forms of problems that include word problems. First, they complete the puzzle to illustrate how words identified about the variables relates to the statement given. Then, students complete the table at the bottom to rewrite the expressions for the cost using multiplication instead of repeated addition.
In this algebra instructional activity, students identify the slope of a line, solve algebraic equations with absolute value, and identify the domain and range of given functions. This three-page instructional activity contains 21 problems.
Students analyze pairs of coordinates for functions. In this algebra lesson, students differentiate between relation, function and non-function. They match up the input and output to identify the domain and range of each relation.
Eighth graders work together in groups to discover linear functions. They are giving a situation and they are to recreate it in their groups. They answer questions to complete the lesson.
