Tip—start with the inner most nested grouping symbol. The resource provides an explanation of the conventional method in nesting grouping symbols and using parentheses, brackets, and braces. The video provides two examples, one involving...

This equation with a variable on both sides and parentheses on both sides seems like it will be hard to solve. Don't despair! It's not as complicated as you might think. Just use the order of operations and take it one step at a time.

Use common factors to simplify expressions. The resource introduces factoring out the greatest common factor to simplify algebraic expressions. Worked examples include basic linear with numerical common factors to expressions that have...

Order really does matter! Show your class how order makes a difference in solving equations. The presentation uses the order of operations in reverse as a guide to help solve two-step equations. Continuing, the video shows how to solve...

Expand your understanding of the distributive property. Scholars learn how to apply the property to algebraic expressions by watching a video. They expand expressions with their newfound knowledge.

Demonstrate the order of operations and the way to evaluate numerical expressions containing grouping symbols and exponents. An instructive video introduces learners to the mnemonic PEMDAS, which is a great way for them to...

Investigate with your classes the meaning of absolute value. Here, the instructor explains the definition of absolute value and uses the definition to evaluate different expressions. The expressions include simplifying within the...

What comes first, the exponents or the multiplication? Follow the order of operations and you will never make a mistake! Young scholars learn the order of operations and then watch as the instructor evaluates a five-step problem. The...

Here's a video that presents several numerical expressions to be evaluated using a calculator.Viewers come to realize that sometimes it is not just a matter of punching in the numbers, but they also need to be concerned about how...

Use this video to show older elementary mathematicians that they can compare numbers using the same thinking that they did when they were in the first grade. Sal compares decimal numbers using the greater than and less than symbols. He...

Simplify an expression by following the order of operations. Some already know the acronym PEMDAS. But that often gets a little confusing. The teacher demonstrates three steps to simplifying an expression.

Sal factors and finds the difference between the two cubed terms because this comprehensive presentation would be perfect as homework support or as an independent workstation.

Please Excuse My Dear Aunt Sally - or whichever mnemonic your students use for the order of operations - is the focus of this video. Sal takes viewers through various mathematical equations that require the use of the order of...

Are you stumped by having a fraction in front of the parentheses in an equation you are trying to solve? Never fear. Watch as the instructor shows you how to work your way through this equation starting with the distributive property and...

So you have a variable on both sides of the equation. How do you solve this kind of equation? Just get like terms together on each side of the equation and then isolate that variable.

A direct instructional video of how to solve an inequality when you have the same variable on both sides of the inequality sign, this resource could be used in class or at home.

So you have a variable on both sides of the equation. How do you solve this kind of equation? Just get like terms together on each side of the equation and then isolate that variable.

When presented with categorical data, a two-way frequency table is a great way to summarize the information. Pupils organize categorical data using a two-way table, then use the tables to determine missing data and to calculate simple...

How likely is it to draw a blue marble? Pupils find the likelihood of events and connect that to the probability of the event. They find the probabilities of simple events and show their probabilities on a scale.

Make an estimate by getting in line. The class works with scatter plots and lines of best fit to make an estimate for given values. Pupils determine whether there is a positive or negative correlation and draw a best-fit line. Using the...

Frequency polygons are a different way to represent frequencies over intervals. Pupils take frequencies for intervals of data from a frequency table and plot them as a frequency polygon. Budding mathematicians find information about the...

Which scenario is the better deal? Class members examine nine scenarios to determine which choice offers a better deal. Pupils decide whether they need to find unit costs or total prices to compare the two options.

The sixteen problems in this resource present opportunities for pupils to practice substituting into algebraic expressions. Scholars evaluate algebraic expressions for given values of the variables. In a few cases, class members need to...

Viewers are presented with seven problems with parallel lines and angle relationships and must use the given information to find the measures of specific angles. To finish, they explain their process in finding the measures in the...
