Rewrite a quadratic function to easily see the transformations involved. The instructional task takes a general quadratic function and rewrites it into a form that shows the translations and scaling of the parent quadratic function. The...

Lesson 21 in a series of 36 specifically focuses on elements and their compounds from groups 13, 14, and 15 on the periodic table — including boron, carbon, aluminum, silicon, nitrogen, and phosphorus. Classes learn how some of these...

Discover one more step to being able to solve any one-step equation. Scholars continue their work with one-step equations in the 28th installment of a 36-part module. Tape diagrams and algebraic processes introduce how to solve one-step...

Should the United States ban the death penalty? Scholars use real-life examples of criminal activity to come to their own conclusions on the death penalty. Primary source documents, as well as video clips, open the issue of capital...

Should people be more worried about cell phone radiation? Scholars read extensive background information about the issue to prepare for a class discussion or debate. As they explore the website, they learn the main arguments for and...

Expand trigonometric ratios beyond right triangles. Pupils start with a review of trigonometric ratios and then take a look at angles in standard position to determine their measurements. Scholars discover how to find coterminal angles...

Students study and observe the patterns made by the areas of the Sierpinski Triangle. Students use the computer to draw two or three iterations to discover the number patterns. Students complete worksheets based on Geometric Fractals.

Ten similar worksheets plus their answer keys are included in this resource. Each simply displays three right rectangular prisms with their length, height, and width printed on them. Fifth graders apply the formula for the volume of a...

Students identify properties of triangles. In this geometry lesson, students differentiate between similar and congruent triangles. They use the umber of sides to help define the angle of the polygon.

Just because we have the ability to determine an organism's traits through genetic testing, should we do it? Middle-school medical experts examine the ethical dilemmas in biotechnology in the 18th and final installment in a series of...

In this triangles activity, students identify 3 triangles by the length of their sides and 3 triangles according to their internal angles.

Middle schoolers examine various triangles and discuss how similar triangles have sides that are proportional. They utilize an ancient Egyptian method to determine the height of a flagpole.

In this ratio instructional activity, students investigate the relationship between the ratio of two sides of similar triangles. Afterwards, they convert fractions, decimals, and percents. This three-page instructional activity...

Young scholars use Geometer's Sketchpad to examine the scale factor when in is applied to the length of a figure's sides. They look at how the scale factor affects the side lengths, perimeter, and area of the figure that result. They...

Students study relationships between angles, side lengths, perimeters, areas and volumes of similar objects. In this lesson students also create and critique inductive and deductive arguments concerning congruency, similarity and the...

Learners draw a picture of an African city that is similar to  a U.S. city and discover how other parts of the world have the same types of buildings. In this global similarities instructional activity, students create a map of...

Students explore the similarities and differences among their classmates. They are introduced to the Civil Rights Movement-that all people be treated equally and fairly. Students discuss the importance of appreciating individual...

Students draw a picture of an African city that includes places similar to those found in U.S. cities. After listening to Somewhere In Africa, students identify places or buildings from the book and apply them to the creation of their...

First graders compare and contrast adult and baby animals to identify similar characteristics shared by both.

Students identify a right angle and right triangle. They perform WebQuests searching for similar figures and solve for the length of one of the sides given the other two.

Learners use triangles to find the length and slope of each side. After connecting the vertices, they add points based on their specific instructions. They use the Pythagorean Theorem to complete a worksheet to end the lesson.

Students explore geometry by participating in a class card game. In this triangle lesson plan, students utilize playing cards with shapes on them which they group up and discard, similar to "Old Maid." Students complete a worksheet and...

Students investigate image and pre-image. In this geometry lesson plan, students identify the reflection and rotation of different shape on a coordinate plane. They identify similarities and differences of image and pre-image of a...

Learners analyze different polygons by shapes and sides. In this geometry lesson, students differentiate between similar and congruent polygons. They name the different polygons based on the number of sides.
