Geometric transformations are explored by high schoolers. They will create a set of instructions for plotting coordinates representing an original transformation of a real-world figure. These instructions are shared with middle...

Grab your youngsters' attention by reading the poem, "Smart" by Shel Silverstein. The son in the poem was not smart in how he handled his money. Mathematics whizzes help him out by using ratio problems to re-calculate his money exchange....

In this 2-day lesson focused on exponents, middle schoolers will cross the curriculum by engaging in science, history and language arts activities. Exponential growth will be explored using grains of rice on a chess board. Exponential...

The class explores a real-world application in which the data represents rental prices of beach condos. They problem solve by multiplying matrices to determine the cost of each property in each season. Several scenarios are presented in...

The teacher illustrates several ways to look at what the domain is in a set of numbers. Input, output, table, graphs, and diagrams are a few of the ways in which she illustrates the meaning of domain.

Don't panic! There is a pretty simple straightforward formula to solve this problem. Some of the words are a bit overwhelming: indirect variation, inverse, constant of variation, indirect proportionality. But one simple formula and just...

So you need to find the midpoint between two cities on a map. If you know the coordinates of the two cities then you can use a formula to figure out the midpoint. It really is as easy as that. Check out this video to see the formula.

Scale drawings are used to represent many things. Scales are used all the time on maps, and in architectural drawings. Watch this video as the instructor illustrates a simple drawing of a blueprint to represent the footage of an actual...

A model car, a life size car, now compare their sizes. Hmmm. Ok, set up a proportion and then figure out a ratio, and now you can express the relationship in terms of scale. Watch this video and the teacher will demonstrate just how to...

The video just before this lesson showed how to do unit analysis and rate conversions. This lesson also shows conversion of unit rates, feet, miles, seconds, hours. So pay attention and learn how to figure out how many feet per second...

In this word problem, the skill to remember is to match up the similar measurements. This means the inches match up with the inches and the feet match up with the feet measurements. This problem is a ratio and is written as fractions....

Ingrid got some good advice from her father about building a bridge out of pasta. Now she has to do some calculations to build a strong pasta bridge. Figure out how tall she can build her bridge based on a given length. Two given values...

It just doesn't seem right to lose points when answer a question incorrectly. Well, that's what this word problem is all about. So calculate how many incorrect answers the team gave. Don't forget to flip the inequality when dealing with...

It's not a complicated word problem, but the picture frame just gives the problem a little context. So you are trying to find the difference, which means subtraction. The instructor reviews how to distribute the negative sign to the...

So x amount of people were surveyed and 68 of them said algebra was their favorite subject. Set up a percent proportion to identify the number of people surveyed. That's often the hardest part, setting up the equation. So observe the...

Trying to figure out how much something is marked down? There are a few steps to get your answer so follow along and watch as the instructor takes you through the process.

Broken lights at the skating rink? Are there enough not broken to be able to see well enough to skate? Set up this real-world word problem and find the total number of lights in the skating rink. Two given values and one variable. Solve...

Solve this real world word problem in just one written step. The original inequality is a division problem, so to solve it, use the multiplication property of inequality. Was the problem solved by multiplying a negative number? Yes! So...

A word problem with one variable and two given numbers. This word problem seems doable from the start. Wait, it's an inequality. Don't worry about that piece, just get the expression written and do the math. Watch this video and see how...

A word problem that needs to be written as an inequality to solve. This expression seems pretty straightforward and only takes one step to solve. But wait, the division property was used with a negative number so the inequality sign has...

Don't be afraid of this word problem because it has an inequality. There is only one variable and this inequality can be solved in one step. It's pretty straightforward.

Word problems. Inequalities. Money. What? Does Marissa have enough money left in her bank account to go to the movies? One variable, two given amounts. Set up this inequality to determine how much Marissa needs to have in her bank...

Don't skip this word problem! Take one piece at a time in writing out this inequality. Once you have an expression that represents the words in this inequality, the rest will seem easy. So watch this video to get a better understanding...

If you know two values and are looking for a third, you can set up an equation and solve to find your answer. In this problem you know distance and time, and you are looking for rate of speed. Use the distance formula to set up your...
