Given an algebraic expression, write a word problem. Usually it's the other way around where you have a word problem and need to write an algebraic expression. But, this is a good skill to have because it would mean that one has a good understanding of the relationship between words and algebraic expressions. It would probably make solving future word problems a bit easier. So watch this video and practice this skill.
Being able to translate words into a mathematical expression is an important skill, but being able to go the other way is just as crucial. Watch as the teacher takes a simple algebraic expression and demonstrates how to translate that into a verbal expression.
Solve this algebraic equation in one step by using the multiplication property of equality. Not sure what that property is? Then watch this video and see the instructor work out this problem. These are decimal numbers so make sure to use the rules that apply to multiplying decimal numbers.
Divide, dividend, divisor? Will the real divisor please stand up? How do you know which part of a division problem is the divisor when you have a rational expression of algebraic fractions? Just remember it's the second number or the one you are dividing by.
Multiply algebraic fractions. But first cancel or reduce the numerators and denominators, then do the multiplying. Cancel out the common factors in these monomials. It is always a good idea to reduce as much as possible before multiplying. It is much simpler to do it before than having to reduce numbers after they have been multiplied.
You've got some algebraic fractions in an equation and their denominators are all different. Well, first you need to strategize. Then find the excluded values that make your denominator equal zero because we know the denominator cannot ever be zero. Next find a least common denominator for all three terms. Multiply the terms. Then simplify. Now you are getting closer to solving the equation. You solved it and have a value for your variable. But now you need to check it, by plugging in the value. Does it work?
Have your class figure out how much "Teddy" weighs on the moon and how to translate words into algebra! This video shows pupils how to take a word problem, and then solve it using the direct variation formula and given information. Great if your class is working on direct proportionality and word problems.
This algebraic expressions and equations worksheet includes 14 short answer problems that require writing verbal expressions, and translating verbal expressions into algebraic expressions.
Express a series of events from a story using algebra. Learners are told a story about two children. Each child in the story has a specific amount of money. They then use algebraic expressions and number sentences to express each child's amount.
In this instructional activity, learners identify the Fundamental Theorem of Algebra. They solve polynomial functions and simplify expressions and equations. 
Students examine various algebraic terms. They simulate the addition of like terms and adding and subtracting coefficients by acting out the variables.
This is a lesson in solving linear equations. More specifically, students will see how to solve an equation with a variable expression in the denominator of a fraction.
Take everything your learners know about combining like terms with the commutative, associative, and distributive properties, and put it together in one lesson. This last video in a series of seven, takes all the prior knowledge and shows you how it all works together. Demonstrates two examples and explains each step. 
Fifth graders examine variables in algebraic equations. Working in partners, 5th graders write algebraic expressions from real life word problems. Students work together to write their own word problems. They trade papers and write more equations from the information given.
In this algebra worksheet, mathematicians identify important vocabulary related to solving equations. They create and simplify expressions and solve word problems. There are a total of 10 questions that provide a good review of the first year of algebra. 
In this translating algebraic inequalities worksheet, learners solve 15 short answer problems. Students write and solve algebraic inequalities given a word problem.
For this algebraic fractions worksheet, learners solve and complete 20 different problems that include solving equations that contain algebraic fractions. First, they determine the common denominator in each and use the product of all the denominators. Then, students multiply, simplifying each term as usual, then solve the remaining equation.
In this expressions worksheet, students solve and complete 30 various types of problems that include defining both verbal and algebraic expressions. First, they translate each verbal expression into an algebraic expression and vice verse. Then, students evaluate various expressions and determine the perimeter of a rectangle that has a given length and width.
In this writing equations worksheet, students read word equations and write them as algebraic equations using x to represent the variable. Students write eight short answers.
In this algebraic problem solving worksheet, 6th graders use different problem solving approaches to completing an assessment of algebra skills. There 5 pages in this assessment.
