T-Shirt Lettering

Which deal is best? Learners determine which of two companies has the best deal for a particular number of shirts. They begin by creating a table and equations containing each company's pricing structure. Individuals finish the seventh...

Skittles and math? Pupils will work as a class to determine how many orange Skittles are in a large bag by using proportions. They will problem solve, estimate, and share their thinking. Then, they will each receive a small bag of...

Address any kind of math concept or problem with a series of problem-solving strategies. Over 12 days of different activities and increasing skills, learners practice different ways to solve problems, check their answers, and reflect...

Everyone loves a sale! As pupils investigate a sale on t-shirts, they determine the percent discount and original prices.

When guess and check gets old, it's time to start graphing! An instructive lesson explains how to solve a system of linear equations using graphing. Equations are in both slope-intercepts and standard form. 

There is no better way to present a math problem than within the context of a story. Sal explains how he divides a fraction to solve a word problem where he must determine how many shirts can be made with 48 yards of fabric. Problems...

In this video, Sal solves a word problem sent in by a listener that has two cyclists riding towards each other over a given amount of time. It is an interesting problem regarding ratios and the relationship between distance, rate, and...

The instructor uses the formula for temperature to show how the variables can be moved around to solve a problem.

Extend an understanding of ratios and proportions to include unit rates. The video lesson compares two prices of different sizes using two methods. The instructor first calculates a unit price for each product and compares the costs. The...

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.
