Find the area as it slides. Pupils derive an equation to find the painted area of a section of a trapezoidal-shaped stage The section depends upon the sliding distance the edge of the painted section is from a vertex of the trapezoid....

A set of 49 math vocabulary cards ranges from angle to irregular polygon to parallel lines. Each sheet contains two cards: one with the word printed in bold text and the other with the definition.

Middle and high schoolers explore the concept of slope. In this slope lesson plan, learners graph lines using a life-size graph. They use chalk on a blacktop to create a coordinate plane and use each other as the tick marks on the grid....

The shortest distance from point A to point B is a straight line—or is it? Young scholars determine the shortest route either along a circular path or through the center of the circle. Learners gain a unique perspective on arc length and...

The truth will always come out. A short performance task has learners considering a witness statement given to a detective. They apply special line segments in triangles and Ceva's Theorem to prove that the witness is actually lying.

Just how far away from the mean is the data point? Pupils calculate the standard deviation for a set of data and find out how many standard deviations a point is away from the mean. The teacher leads a discussion on how to calculate...

Every war has a number of turning point battles that define the outcome. Inform learners of three major battles of the American Revolution. The Battle of Bunker Hill, Saratoga, Yorktown and the Treaty of Paris are each discussed. Maps...

Young learners examine different places in their neighborhood using informational texts. First they identify a place that they like to play and predict if it will be in the nonfiction book Community at Play.They will share their favorite...

Here is a comprehensive package in which middle schoolers learn about types of seismic waves, triangulation, and tectonic plate boundaries. Complete vocabulary, colorful maps, and a worksheet are included via links on the webpage. You...

Practice with unit rates, proportions, and ratios when Carlos purchases an amount of bananas. Learners must interpret a graph to decide whether points on the same line represent similar proportional relationships. Use with lesson plans...

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...

Middle and high schoolers perform transformations. In this web based lesson, students explore dihedral figures. They use the web tools to translate, rotate, and reflect figures. Pupils identify lines of symmetry.

Sometimes the best view is from the farthest distance. Satellite imaging makes it possible to create altitude maps from far above the earth. A three-part activity has your young scientists play the role of the satellite and then use...

Just in time for the start of the Winter 2018 Olympics, you can track the Olympic torch relay through the Republic of Korea. But there must be some math involved, right? Give learners a worksheet that prompts them to calculate the...

Students calculate distance on a map by using a mileage scale to calculate the distance from their hometown to Niagara Falls. They, in groups, determine the best route, then compose stories about their journey to Niagra Falls.

Students create a table of values to graph a line. In this algebra lesson, students identify the slope and intercept of a linear equation. They use a Ticalculator to graph their function.

Students identify the slope of a line. In this algebra lesson plan, students label slopes as positive, negative, zero or undefined. They use the slope formula to find the slope algebraically and graphically.

Fourth graders watch a video about mapping distances and then calculate the distance their individual mushers travel each day. This occurs each Monday through Friday until each musher has crossed the finish line in Nome Alaska.

Students use the Geometer's Sketchpad to illustrate possible answers to a parallelogram problem. As a class, they discuss the point-slope and linear equation forms. Individually, students solve their equations and check the results on...

Students explore distance a toy car travels by changing the amount of batteries used to power the toy car.  In this force and motion lesson, students calculate the average speed of a car while investigating the power from various...

In this plane geometry worksheet, students combine the basis of plane geometry and linear problems to solve problems. They determine total surface area, the length of a line, and the sum of the edges of a three-dimensional figure. This...

In this linear and planar geometry worksheet, students use the Pythagorean Theorem, equation of a line, slope of a line and area formulas to solve problems. This three-page worksheet contains seven problems.

In this plane worksheet, students find the midpoint of a line, determine points on a plane, and use the cross product to find an equation with given parameters. This two-page worksheet contains three problems.

Students investigate the properties of lines and congruent triangle theorems as well as apply geometric properties and relationships to real-world mathematical problems. Given two different scenarios, they examine maps that have been...
