Scholars can use area formulas, but can they apply what they know about area? The lesson challenges learners to think logically while practicing finding area of shapes such as rectangles, circles, parallelograms, triangles, and other...

In a scale measuring noise, an increase in 10 dB is a 10 time increase in power. Mathematicians examine the data graph of a real world exponential growth, with no logarithmic scale, and then create two equations relating the...

Conduct an investigation on the plants used by the Hohokam tribe. To survive in the harsh desert environment the Hohokam used many natural resources. Learners read, research, map, and graph multiple aspects of Hohokam plant use as a...

Students study about our dependence on the earth's resources for materials. They practice their knowledge of geometric shapes by recognizing them in the context of the story.

Numbers that are very large or very small are difficult to express in standard notation. Pupils learn how to convert between standard and scientific notation. They also multiply and divide the numbers in scientific notation. 

Analyze trends in the stock market using histograms. Future economists use data presented in a histogram to find periods of greatest increase and decrease. They also draw conclusions about days that would be best to invest.

You won't want to flush a great lesson down the drain! An intriguing resource asks learners to predict the number of sheets of toilet paper on a roll. Presented with the dimensions of the roll and one sheet of paper, scholars make...

Linear, square, and cubic units are all investigated as different types of packages are measured. The teacher will need supplies such as a box of aluminum foil, a package of ribbon, and a bag of mulch. The class determines the...

Students investigate the concepts of volume for rectangular prisms and spheres. They measure the volume of one balloon and then consider how many breaths it would take to fill the room with balloons. The rectangular prism being measured...

Upper graders use the properties of right angle trignonmetry to measure objects such as the school flagpole. They solve real world problems using these properties.

Elementary math classes calculate the area of a shape and explain the correlation between the size of the perimeter and the areas that can be contained within that perimeter. They also explain the effect the shape of the perimeter has on...

Geometers find the perimeter and area of rectangles. They discuss the definitions and characteristics of rectangles and squares. In groups, they use yarn to discover the perimeter of squares and rectangles. They count cubes to explore...

Upper graders use a variety of tools to measure liquid and solid ingredients in an ice cream making recipe. Following written and oral directions and accurately timing themselves forms the basis of this lesson.

Students review what a cylinder is and how a cylinder is measured. They build a variety of cylinders with different heights and radii. They compare the surface area and volume of each cylinder and discuss anything that surprises them...

Young scholars discover how to calculate speed, distance, and rate. In this problem solving lesson, students view an episode of "Cyberchase" and use the distance formula to determine the fastest route that the main character in the...

Would you measure the height of a living room in centimeters? Scholars examine which units would be most efficient for this project: centimeters or meters. There is only one question here with a detailed explanation below. This would be...

Students carry out a cost analysis. In this comparative math lesson, students compare the cost of equal measures of gasoline to mouthwash, house paint, fruit juice, white-out, and other liquids.

Young mathematicians calculate the area of rectangles and squares. In this geometry lesson, learners are grouped in pairs and use geoboards to construct rectangles. They calculate the area of the figure by counting the number of square...

In this math graphs worksheet, students write line plot, tally chart, pictograph, or bar graph to tell the best kind of graph to use to answer the six questions.

Students engage in a lesson that is about the concept of polygons and focuses upon finding the area. They use formulas provided in the lesson in order to solve problems given by the teacher for independent practice. Geometric figures are...

There is only one area calculation problem here, and it is followed by a detailed explanation. Consider projecting this as a teaching tool, covering the answer until learners have shared their own. They are instructed to draw a rectangle...

Students calculate the square root of a given number using carpenter's square measurements. In this math lesson, students relate this method on the Pythagorean theorem. They answer practice problems after the exploration activity,

Students measure distances using indirect measurements. In this geometry lesson, students apply proportion and ratios to measure heights of different objects. They differentiate between direct and indirect measurements.

Students accurately measure several dimensions of common objects using calipers. They determine whether a manufactured product meets correct specifications for length, width, height, depth and diameter.
