Let's all take a moment to review what we've learned. Scholars look back and reflect on their work from a unit on least squares regression. Reflection is important for teachers, too, which is why the lesson gives a chance to consider how...

Can you see the function in the table? A calculator activity helps learners analyze data tables. They use technology to create scatter plots and calculate a regression function to fit the data. This is the first in a series of two lessons.

Calculating taxes doesn't need to be so taxing. Future taxpayers use given tax rates to discuss how to calculate income taxes. Based on what they learn, they determine the amount of tax a family would pay based on a certain income.

Compose discounts to find the final discount. Pupils investigate compositions by first looking at numerical representations of multiple discounts taken on a product. Learners develop functions for each discount and compose them to...

Perform main investigations of functions across the real numbers. Using a graphing calculator, pupils create graphs of functions and view their tabular information. With the aid of the graphs and the tables, learners determine the...

Your learners will explore the idea that not all functions have real numbers as domain and range values as seen in this real-life context. Secondly, the characteristics required for a function to have an inverse are explored including...

Just like functions are the basis of algebra, the tower in this activity has a base connecting the drawing to an algebraic equation. Can your mathematicians spot the pattern of this tower and other hypothetical towers by creating a...

One in, one out is what functions are about in a video explaining the rules and qualities of these relationships. Have your learners practice with ordered pairs, tables, mapping, and graphs, deciphering whether or not those relationships...

Relationships can be good or bad, but functional relationships are the best! The video demonstrates relationships in a table or graph and what makes their qualities functional. Have your learners review functions and then go through a...

The teacher illustrates several ways to look at what the domain is in a set of numbers. Input, output, table, graphs, and diagrams are a few of the ways in which she illustrates the meaning of domain.

Sal guides viewers through questions 24-27 of the MTEL Practice Math Test in this video, showing them ways to both read the problems carefully and solve the equations correctly. He uses process of elimination in a few questions, modeling...

This video tutorial does not include narration, but great math music. It describes how to evaluate a function for a variable through example, and procedure. This would be a great clip to assign as homework for learners just beginning to...

FOIL to solve! That's easy, if you know how. If you don't it's OK, you can watch this clip and watch as the tutor describes how he solves functions involving multiplication and division using the FOIL method and factoring. The notation...

This clip covers a lot of ground and is perfect for those needing a little extra help remembering how to graph a quadratic function. It begins with a multi-step problem which requires the learner to graph a quadratic function, set up a...

The teacher illustrates several ways to look at what the domain is in a set of numbers. Input, output, table, graphs, and diagrams are a few of the ways in which she illustrates the meaning of domain.

In this functions worksheet, high schoolers solve 70 short answer questions. Students find domain of functions and evaluate them for a given value. High schoolers determine if a mapping diagram represents a function.

Play Jeopardy and review these concepts before that upcoming test. Make sure the class has a good grasp of: order of operations, solving equations, and understanding functions. There are a few miscellaneous related concepts for review also.

High schoolers are introduced to the techniques associated with interpreting functions. The vocabulary associated with this technique is reviewed, then pupils view a PowerPoint (embedded in the plan), that shows how to interpret...

In this graphing calculator worksheet, students explore how to generate a table for a specified function and then create a graph of the function. Seven short answer and one multiple choice question is provided for individual practice.

The teacher illustrates several ways to look at what the domain is in a set of numbers. Input, output, table, graphs, and diagrams are a few of the ways in which she illustrates the meaning of domain.

The teacher illustrates several ways to look at what the range is in a set of numbers. Input, output, stem and plot table, graphs, and diagrams are a few of the ways in which she illustrates the meaning of range.

Elementary schoolers use a function machine in order to help them look at the relationship between input and output, and to look at the rule for the change. The machine is actually a cardboard box, and it serves quite well for the...

Learners identify the different angles using the properties of trigonometry. In this trigonometry lesson, students find the coordinates of the terminal side of an angle in standard position.

Several examples of equations in slope-intercept form are the focus of this video. Instructors who are reviewing slopes and functions with their math classes, or who are introducing the concept for the first time, will appreciate Sal's...
