Just when a young mathematician starts to feel comfortable turning word problems into linear equations, shake things up and throw inequalities in the mix. This excellent, instructive presentation takes the steps for solving an...

The accuracy required by the design and measurement of an Olympic running track will surprise track stars and couch potatoes alike. Given a short introduction, the class then scaffolds into a detailed analysis of the exact nature of the...

Scaling is a practical skill as well as a topic to be addressed throughout the Common Core math standards. You are given three different presentations and a detailed teacher's guide to use while teaching proportion, as well as practice...

At what point does data switch from being an outlier to part of the average? Scholars view conflicting news articles about protesters. They must decide which, if any, side is using the correct sample to draw their conclusions. It's a...

The lesson plan provides a richly detailed narrative and sample problems for teaching or reinforcing how to work with percentages. In particular, your audience will compute the costs per serving of food and simulate setting menu prices...

This detailed presentation starts with a review of using key components to graph a line. It then quickly moves into new territory of taking these important parts and teasing them out of a word problem. Special care is...

In this business and statistics worksheet, students read real-life business problems, arrange data, and identify the probability method best used to determine the answer. They identify the type of random sample, draw stem-and-leaf plots,...

Of particular interest to a group of business and finance pupils, this lesson explores depreciation of automobile values by comparing the double declining balance to the straight line method. Mostly this is done through a slide...

A comprehensive lesson on acceleration awaits your physicists and engineers! Two YouTube videos pique their interest, then sample F=ma problems are worked and graphed. The highlight of the lesson is the building of a Lou-Vee air car!...

We've talked a lot about energy, but where does energy come from? Pupils brainstorm different energy sources through a class discussion to kick off the 14th installment of a 25-part Energy Systems and Solutions unit. They then research...

This activity focuses on unit conversion, proportions, ratios, exponents, and the metric system. Discuss measurement with your math class and demonstrate how to solve several health-science word problems. Give learners a chance to visit...

Students perform activities involving ratios, proportions and percents. Given a newspaper article, groups of students count the number of letters in a given area. They use calculators and data collected to construct a pie chart and bar...

Students employ their five senses to interpret and duplicate instrumental patterns. Following the teacher's patterns, students clap their hands and later use instruments such as bells, triangles, or cymbals to create their own "songs."

First graders investigate the aspect of time, including days of the week using a calendar. They use problem solving strategies and a monthly calendar to find a solution to the problem.

Students discuss the subject of coins and heads and tails. They work in groups to solve Fran's problem concentrating on the fact that the coins are in a row. Any group that finishes early can try the Extension problem.
