It used watt amount of energy? This resource investigates the power usage of small household appliances. Using a watt meter, groups measure the actual wattage used by an appliance and then calculate the energy used daily. 

The history of math is fascinating! Utilize a woodcut primary source image from 1492 and posters from the 1930s to help geometers apply their volume-calculation skills to real-life questions. 

Let your class bounce to examine the concept elastic potential energy. Individuals bounce on a pogo stick in order to calculate its elastic potential energy. Groups then compare the elastic potential energy to the gravitational...

Students study data on the nutritional value of Burger King meals in order to discover its nutritional value and also to compare the meals, using mathematical computation, to the recommended daily diet. In this data handling lesson,...

Graph it! Investigate transformations with a graphing calculator. Pupils graph sets of linear functions on the same set of axes. They determine how changes in the equation of a linear function result in changes in the graph.

Eighth graders investigate percents by comparing different discounts on the same sale item, practice graphing percents, and look at reasonable and unreasonable "percents off" a sale item.

Learners use, with increasing confidence, problem-solving approaches to investigate and explain mathematical content. They make and test conjectures. They use tables and graphs as tools to interpret expressions, equations, and inequalities.

Sixth graders will practice dealing with whole numbers using the order of operations and performing calculations using the four basic operations. The activity also includes practical investigation into the use of rational numbers.

Young scholars investigate the four basic operations of mathematics that are addition, subtraction, multiplication, and division. The use of a technology game is part of the lesson. They demonstrate the proper use of a calculator as part...

Sixth graders investigate unit pricing to find which cup of coffee is a better buy. They use ratio and proportions to solve problems involving a change of scale in drawings, maps, recipes, etc. Students determine the unit cost of items...

Seventh graders investigate placing parentheses and using the order of operations appropriately to make true sentences. They use the order of operations within a problem and the use of parentheses and their relationship by the order of...

Students will examine solids to determine which has the least surface area. They will also understand the use of units, square units, and cubic units. There is also the teaching and application of geometry formulas to perform calculations.

Preparing the root tip samples is the most challenging part of the mitosis-viewing lab found here, but the directions help ensure you have everything you need. There is no worksheet included; however, there is a sample data table....

Context is the key to understanding slope. A real-world application of slope uses a weight loss scenario with a constant rate of change to introduce the concept of slope of a line, before it makes a connection to the ordered pairs...

Go with the flow and use a helpful resource. A set of two activities has learners investigate flow rates. They first determine the flow rate of a faucet by measuring how long it takes to fill a bucket. Using the results, they make a...

The humble soda can gets the geometric treatment in an activity that links math and science calculations. After a few basic assumptions are made and discussed, surface area calculations combine with density information to develop an...

There's no risk of injury when working with virtual HCl! Challenge your young chemists with making calculations to create a 3M solution of HCl from the concentrated acid. They first calculate the correct ratios of HCl and water and then...
