Stating that "the fun thing about algebra is that you can always check your answer," Sal demonstrates the simplest ways to solve several algebraic equations. He specifies that viewers should focus on the steps he's taking and why he's...

If your math students are having a hard time with graphing and slopes, this video could be a great resource as they prepare for the SAT. Sal takes care in explaining his thought process, making sure where to note different strategies to...

Choosing the "quick and dirty" method of solving problems rather than more mathematically complicated, Sal shows students the importance of time management when taking the SAT (or other math tests). He still arrives at correct answers,...

Here is a complete and clear demonstration of the process needed to factor a trinomial with a non-1 leading coefficient. Sal uses various colors and provides working examples while he factors the simple trinomial. This video would be...

Combine those like terms! What does that mean? How do I do that? Find terms with the same variable and find terms with the same powers and combine their coefficients.

The instructor demonstrates how to line up two polynomials vertically to add them together. She emphasizes lining up the terms with the same powers. She also identifies some places where there is no term and shows how to write a...

There are a lot of steps in this problem. But just like walking up a flight of stairs, you should take one step at a time, so too in the solving of this problem. The instructor explains each step and what to do to move to the next one.

Combine those like terms! What does that mean? How do I do that? Find terms with the same variable and find terms with the same powers and combine their coefficients.

Do you want to combine like terms the long way, or the quick way? Well, the instructor shows you both ways, and I bet you will prefer to combine like terms the quick way.

In this chemical equations worksheet, students learn to balance chemical equations by counting the number of atoms of each element in the products and reactants and making them equal. This worksheet has 5 problems to solve.

Although only 4 slides long, this brief presentation summarizes how to balance equations very clearly.  There is an example of how to balance equations incorrectly, followed by some rules and guidelines that show the correct method. ...

After recapping some of the basic terms used in reactions, this PowerPoint will be useful to your class by demonstrating some examples of forming equations.

The instructor demonstrates how to line up two polynomials vertically to add them together. She emphasizes lining up the terms with the same powers. She also identifies some places where there is no term and shows how to write a...

Radicals , radicands , square roots, perfect squares, and subtracting? Sounds complicated, especially because the radicals are not the same in this problem. So, there's a lot of math work to do here. Watch this video to find out how to...

Writing a quadratic equation in standard form gives values for a, b, and c that can be used to find several pieces of information about the graph of the equation. Knowing a, b, and c-values allows one to find the axis of symmetry, the...

There are a lot of steps in this problem. But just like walking up a flight of stairs, you should take one step at a time, so too in the solving of this problem. The instructor explains each step and what to do to move to the next one.

The teacher illustrates how to write a quadratic polynomial in standard form. There are a few rules to follow: all like terms must be combined, it must be written in order left to right as the degrees drop, and the coefficient of the...

In this chemical reactions worksheet, students answer 12 multiple choice questions about compounds, chemical reactions, and balancing equations using coefficients.

In this balancing chemical equations worksheet, students learn how to use coefficients to balance chemical equations. They practice balancing 7 equations and are given one challenge equation to balance.

In this balancing equations worksheet, students balance 8 equations using the proper coefficients. They also write the chemical formulas and balance 8 equations given the reaction in words.

In this balancing chemical reactions worksheet, high schoolers fill in the proper coefficients in front of the reactants and products of 20 equations to balance each given chemical equation.

For this balancing equations worksheet, students balance ten equations by placing the proper coefficients in front of reactants and products to balance the number of atoms.

In this balancing equations worksheet, students identify the number of atoms in given molecules and compounds and they balance ten equations by placing the proper coefficients in front of the reactants and products.

In this balancing equations worksheet, students use an on line source to answer questions about balanced equations and they write balanced equations for various types of reactions. They balance equations using an on line game that allows...
