Rational and Radical Functions Teacher Resources

Fold, fold, and fold some more. In the first installment of a 35-part module, young mathematicians fold a piece of paper in half until it can not be folded any more. They use the results of this activity to develop functions for the area...

There are many ways to approach finding the rational approximation of an unknown square root. Here is a problem that will help math learners make a connection between square roots and their order on a number line. As usual, determine two...

Is there more to college algebra than this? Even though the eBook is designed for a college algebra course, there are several topics that align to Algebra II or Pre-calculus courses. Topics begin with linear equation and inequalities,...

Algebra concepts are all wrapped up in one nice bow. The resource combines all the concepts typically found in Algebra I and Algebra II courses in one eBook. The topics covered begin with solving linear equations and move to linear...

Evaluating expressions require two things- parentheses and PEMDAS. The video starts with an emphasis on using parentheses to plug in your variables. Once you have everything plugged in, PEMDAS will get your mathematicians to the correct...

In this understanding limits, students determine the convergence of given sequences. They use properties of limits to evaluate functions. This two-page learning exercise contains examples and explanations, as well as eleven problems.

Students solve exponential functions and inequalities. In this algebra lesson, students find the roots of equations and use it to graph and evaluate exponential functions. They simplify exponents using the law of exponents.

Rates of change can be a slippery slope. The resource makes the connection between the rate of change and the slope of a line. It continues on to provide examples of how to interpret the slope and the y-intercepts of linear equations...

In this square roots worksheet, students calculate the square roots of whole numbers and rational numbers. Seven problems have multiple choice answers. The remaining 13 problems are short answer. One problem involves graphing a function....

A neat and organized formula handout makes the circle go round, doesn't it? Full of higher algebra topics, formulas and rules, graphs and definitions—there is a way to support everyone in Algebra II or Pre-Calculus. 

Students use the quadratic formula to solve application problems. The first problem relates to the path of a football thrown from the top of the bleachers. Students compute the time it will take the football to reach certain heights. In...

Ensure your eighth graders get the most out of their math education with this series of Common Core checklists. Rewriting each standard as an "I can" statement, this resource helps teachers keep a record of when each standard was...

Clarify the Common Core standards for your eighth grade mathematicians with this series of classroom displays. By rewriting each standard as an achievable "I can" statement, these posters give students clear goals to work toward...

I'll do algebra, but graphing is where I draw the line! Video explains how to find the slope of a line when starting with word problems. It includes positive and negative slopes as well as how to identify intercepts.

Introduce learners to independent and dependent variables with an informative video.The two variables are defined via inputs and outputs. It makes clear that the independent variable is the one that the person has control over,...

Mathematics is not a spectator sport. A video explains how to identify literal equations and why pupils will need to use them. It goes on to describe how to solve for a specified variable.

What is the best method to overcome negativity? Remember your absolute value! An informative video starts with an explanation of what absolute value is and its connection to measurement. It goes on to solve sample problems to help...

You know how to find absolute values and you know how to solve inequalities — but what happens when these two concepts are in the same problem? A YouTube video first reviews absolute values and moves on to solving absolute value...

Introduce your classes to a new world of mathematics. Pupils learn to call trigonometric ratios by their given names: sine, cosine, and tangent. They find ratios and use known ratios to discover missing sides of similar...

In the semester exam, high schoolers solve problems dealing the the discriminant of quadratic equations, systems of equations, linear equations and inequalities. Students also simplify radicals, complete squares, and find the...

Students use optimization concepts to design their own container. For this optimization lesson plan, students understand how the optimization concept is critical in calculus and why products are packaged the way they are.

Find that slope! This video does an excellent job of demonstrating how to use the slope formula to find the slope of a line using two points. The instructor first reviews the definition of slope of a line, then works three problems using...

Clarify complex math concepts with a helpful video. Learners view ways to work with ratios and proportions while discussing vocabulary and notation. After solving proportions, they apply the new strategy to word problems.

A geometry video explains how to solve for midpoint, length of a line, and use the Pythagorean Theorem. It includes multiple guided practice problems for all three equations.
