Young scholars study the formulas for calculating heat energy and how to convert Celsius to Fahrenheit. They apply the formulas on a worksheet.

Students use seconds, minutes, and hours. They then discuss the size of a thousand. After that they read time in digital or analogue form.

Students explore the problem of percentages. Students find a given fraction or percentage of a quantity. Students devise and use problem solving strategies on problems explored.

Students study rectangles. In this math lesson, students use numbers, measurements and geometry to draw rectangles of varying sizes.

Students complete a unit of lessons on basic roof framing. They discuss the various styles of roofs, identify the styles in the neighborhood, cut out rafters using circular saws, and assemble roof rafters.

Students practice performing various accounting functions. Given analysis records, they prepare cost and revenue analysis based on specific criteria. They complete handouts and review their answers as a class. They also discuss the...

Students recognize the correlation between the trash they dispose of around their school and the environmental hazards that face wildlife, specifically the Laysan albatross. They determine three ways that they can help the albatross chicks.

Students explore and complete a variety of activities demonstration probability. They make observations about the results of the activities. Students complete and discuss conditional probability. Also, students draw conclusions about...

Students use Internet software, The Difference Bar, to work out the difference between two numbers by breaking numbers into parts. Students use mental strategies to work out the difference between any 2 two-digit numbers. Students...

Pupils use an Internet tool, The Take-Away Bar" to solve subtraction problems. They use mental strategies to subtract a two-digit number from a larger two-digit number. Students write and solve subtraction problems. They describe the...

In this mathematical instructional activity, students convert fifteen metric units of capacity and multiply and divide whole numbers by 10, 100 and 1000.

Students practice their math skills in determining the water/land proportions of the Earth. Using globes, they locate the seven continents and oceans and determine which covers more space. They use this information to participate in...

Seventh graders develop an examineing of absolute value through real world situations. They develop an examineing of when absolute value can be used in a given situation.
