College Prep Algebra, Signed Numbers

How many ways can you make 10? Class members tackle three problems to find all possible ways three numbers add to be 10. The first is with positive integers, secondly with non-negative integers, and finally with real numbers. Pupils also...

Classmates solve 18 different problems that are mostly word problems that apply algebraic expressions. They draw different combinations of masses on a scale that would balance. They also simplify expressions and solve for x in a number...

Let's hope class participants don't get motion sickness. In the lesson, class members first solve motion problems using tables and graphs. They then use algebraic techniques to solve motion problems.

Build confidence by using multiple approaches to problem solving! This resource uses a visual and algebraic approach to solving application problems. A discussion is included about efficient approaches to different problems.

A series of problems involving exponent properties is the focus of this video. Sal demonstrates rational expressions, simplifying fractions, and how to manipulate algebraic equations using exponents and division.

Three word problems involving measurements, percentages, and expenditures are the focus of this video. Sal shows how to translate word problems into solvable equations.

A brief presentation with laser-like focus, this video talks young mathematicians through the mechanics of simplifying algebraic fractions by factoring trinomials. While the factoring itself is assumed to be a mastered skill, the steps...

Mix it up in math class! The video provides an equation hint to be able to setup mixture problems. Two problems are provided as examples on how to use the equation in order to solve mixture type word problems. 

A few word problems involving age are presented. Starting with a simple problem and progressing to more complicated word problems, Sal uses a chart to organize the information given in the more complicated problem in order to solve for...

Take young mathematicians' understanding of percents into the real world with this series of word problems. Involving a variety of contexts from calculating scores on math tests and savings account interest, to determining sale prices...
