Interpreting algebraic expressions is a fundamental skill in beginning algebra. This lesson approaches the task in numerous ways. First, learners assess their understanding with a short worksheet on converting between words and expressions. They then work in pairs to translate between words, symbols, tables of values, and graphic area representations of expressions. Using card sets to match representations keeps them engaged. All or part of this well-written lesson could be used to evaluate, or extend your students' understanding.  
"Equations 2" is the second video in this series. It follows the presentation titled "Simple Equations." This presentation shows how to solve slightly more complicated algebraic equations, like Ax+B=C. Sal uses visuals (like a number line) to help viewers better understand the equation.
Learners use real data to create an algebraic equation. They explain how the build up of small levels of contaminates can quickly become detrimental to species higher in the food chain.
Sixth graders use squares and cubes to find patterns in perimeter, area, and volume. They analyze algebraic expressions, tables, and graphs to determine patterns, relations, and rules. Finally, 6th graders use Excel to create three graphs, one for perimeter, one for area, and one for volume, using information during the activity.
In this algebra worksheet, students solve a pattern or sequence using geometric and arithmetic formulas. There are 21 questions on 5 different sections.
High schoolers solve linear equations using Cramer's Rule. In this algebra lesson, students use second order determinants to solve equations with two unknowns using a t-chart and identifying solution set. 
Students investigate the achievements of the Chinese in mathematics. In this algebra lesson, students convert Chinese number and decimal numbers and solve a 3x3 systems of equation. They relate art to mathematics also.
Perform data analysis on energy consumption to apply algebraic expressions to the real world. Learners will write and solve equations that answer various questions from residential power use. They will collect data at home and calculate the cost of daily energy consumption. Worksheet to calculate this information is included.
Students explore geometry. In this representing patterns instructional activity, students use algebraic formulas to determine the answers to geometric pattern problems. They work in small groups to discover the pattern and use the formula to find the answer. This instructional activity includes worksheets for this activity.
The instructor illustrates one example of how to write a word problem when given an algebraic expression. The possibilities are as varied as one can imagine. But watch as she illustrates the steps to take in putting a story together.
Pay attention! This is a bit more complicated than having a word problem and rewriting it algebraically. In this problem, do the reverse. Write a story to go with the given algebraic expression. Your class may feel stumped with a problem like this, but watch this video to see how it can be done. The instructor does a good job of explaining step-by-step how to identify the variables and create a story.
Multiply the given algebraic fractions. But first, reduce, reduce, reduce! It is a good rule of thumb to reduce as much as possible before multiplying. So how do you reduce rational expressions? Put the like terms together and cancel the common factors. Watch this video to see how to group the common factors and reduce before multiplying.
Do you know the formula needed to determine the area of a rectangular prism? If you don't it's ok, because this video will refresh your memory, then help you use the formula to find the volume of a rectangular prism. Algebra is used to find missing variable, that's what makes it perfect for geometric application when you have missing information.
Learners complete algebraic equations. They learn the algebraic order of operations and the acronym, PEMDAS, to help them remember the correct order of operations. Pupils complete algebraic equations using the order of operations.
Students change verbal expressions to algebraic equations. They practice the vocabulary of algebraic equations.
Students manipulate integers quickly to get their answers. In this algebra activity, students play an interactive game as they review basic algebraic operations. They add, subtract, multiply and divide quickly to get the correct answer.
Fifth graders utilize input/output tables to help them solve algebraic equations. They incorporate patterns, number sequences and relations to represent and analyze mathematical problems and number relationships using algebraic symbols.
Students take a placement test. In this algebra lesson, students take a test to see what math they should take in middle school. They are tested on algebra, geometry, and probability. They use the results to find a good fit for math in middle school.
Young scholars solve linear equations. In this algebra lesson, students perform addition, subtraction, multiplication and division to solve linear equations. They graph their solutions and analyze their line.
