This videos shows how to use patty paper for coordinate-plane rotations, explaining the rules for 90°, 180°, and 270° turns and how to apply them to any point.

How do I graph sin and cos? In this video, we use the unit circle to derive the graphs for sine and cosine. These periodic functions are very similar, but there are some slight differences.

How do you use the Law of Cosines to find sides (SAS) and find angles (SSS)? In this video, we use the Law of Cosines to find missing sides and angles in oblique triangles.

Learn how to use parametric equations to solve projectile motion problems in this informative and engaging video. We’ll explore the concepts of initial speed, angle of projection, and height above the horizontal to model the path of a...

This is the first of my videos on factoring polynomials using the box method. Factoring polynomials is never easy, but I've seen several different strategies and I love the box method!

This is the third of my videos on factoring polynomials using the box method. Factoring polynomials is never easy, but I've seen dozens of different strategies and the box method is the BEST

This video explains the connection between the box method and the distributive property when multiplying polynomials. The first example multiplies two binomials, while the second example multiples a trinomial and a binomial.

This video explains how to multiply polynomials with the box method. The box method is simply a graphic organizer for multiplying polynomials with distribution

This is the second of two videos on how to factor polynomials using Algebra tiles. It differs from my first video in that this video examines how to use "zero pairs" and negative values.

This video explains how to solve polynomials equations by factoring and using the zero product property

How to simplify when you add, subtract, or multiply radical expressions

In this video, we simplify expressions by using the distributive property and combining like terms.

In this video, we discuss how to simplify expressions with negative and zero exponents.

In this video you will learn how to solve equations with variables on both sides, such as 3x + 3 = x + 7

In this video, you will learn how to solve equations that have fractions by eliminating the fractions first. You will accomplish this by multiplying each side of the equation by the denominator of the fraction you are trying to eliminate

In this video, you will learn how to solve equations that have decimals by eliminating the decimals first. You will accomplish this by multiplying each side of the equation by the a power of ten (10, 100, 1000, etc).

This video explains how changing the slope (m) and the y-intercept (b) in the slope–intercept form affects the graph of a linear function. It shows that increasing the absolute value of m makes the line steeper, while bringing m closer...

This video explains how to graph linear two-variable inequalities. It covers identifying solution and non-solution points, plotting the boundary line, choosing the correct shading, and understanding when to use dotted versus solid lines....

This video shows students how to complete the square with any leading coefficient.

Factoring Polynomials Using the Box Method with GCF: Step-by-Step Example and Explanation.

How to solve word problems using point-slope form of a line. Typically, students are very comfortable using slope-intercept form of an equation, but we rarely see examples where using point-slope form is the most efficient. In this...
