There are an average of three human fatalities by bears in North America every year, which is low when you compare it to the 26 killed by dogs and the 90 killed by lightning annually. The lesson encourages researching human-bear...

Classes look at and analyze primary source images to explore the differences between the colonial regions during the Revolutionary era. They break into groups to tackle each region and then present their findings to the class. A final...

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...

Scholars learn about a series of three challenges when they design a bus system for a small town. They determine the bus routes and then figure out the best type of fuel to use before considering the cost of going electric. Learners...

Fifth graders define the meaning of similar and congruent using concrete objects. They make similar and congruent figures using geoboards. They draw their figures on dot paper, and color their designs.

Tenth graders answer a variety of problems based on similar triangle and learn about the rule of thumb. They will test the rule of thumb by estimating the distance to an object in the classroom.

Students, through lecture and guided practice, discover the properties of similar triangles. They use given measurements of one triangle to find a missing measurement of a similar triangle. They apply this knowledge in real-life...

Start the exploration of trigonometry off right! Pupils build on their understanding of similarity in this activity that introduces the three trigonometric ratios. They first learn to identify opposite and adjacent...

Transformations are more than the process in which sports cars become fighting robots. Listed in terms of which transformations give congruent or similar figures, several resources provide definitions and examples of the four...

Four lessons spotlight a variety of professions while boosting listening and observational skills and making inferences. Lesson one challenges pupils to group cards based on a commonality then justify the relationship they see....

One of these things is not like the other. But, so what? Why is it important to examine the similarities and differences between two entities? Here's a presentation that shows viewers how to go beyond a mere listing to create and...

Use food coloring in electrophoresis. The last segment in a four-part series mimics DNA fingerprinting by using chromatography. Teams conduct chromatography on food coloring to find colors that use similar pigmentation in their makeup.

Researchers use scientific data to understand what is inside each of the planets. The first in a series of six, this lesson builds off of that concept by having pupils use a data table to create their own scale models of the interiors of...

Pairs or small groups work together to determine the height of a tree using similar triangles. Learners make a judgement which direction to let a tree fall to avoid hitting any structures. They then write letters to the principal...

Encoding What I did Last Summer. Class members develop a way to encode a personal experience using a top-down approach to determine components and sub-components of their experience They then pick one portion of the experience and go...

Five questions challenge scholars to show what they know about integers. Using an interactive board game, learners move pieces to discover where a player landed, then answer problems involving both positive and negative integers. 

Help your pupils find a pattern of direct variation. Young scholars use input-output pairs to find a constant of variation and then write the equation. As they build their equations, the interactive lesson provides feedback.

Investigate the process of factoring polynomials by grouping. A detailed lesson initially has learners follow a set-by-step example. They then drag terms to complete the three steps of a new problem. 

Einstein once said "A person who never made a mistake never tried anything new." Enlist his help in teaching young learners the importance of looking for mistakes in hypotheses. An interactive coaches pupils in the falsifiability of...

Who doesn't like pizza?  A creative lesson uses a piece of pizza to explore angle bisectors and congruent angles. Young scholars work through a simulation to create congruent slices of pizza by analyzing an angle bisector. They then...

Build angles from angles. Using the Angle Addition Postulate, learners find the measures of unknown angles. The interactive simulation shows a visual representation of the postulate and allows individuals to manipulate the angles and...

Take the tediousness out of graphing. Using the interactive tool, learners can efficiently create a line graph from a set of data. They then use the graph to answer questions about specific trends in the data.

A lesson challenges scholars to create a cinquain poem. Writers begin by choosing a topic and brainstorm details, then compose their original poem making sure to count syllables.
