Mutations are not just deformed creatures we see in movies—they happen every day! Scholars study the different types of genetic mutations in the 12th installment of a series of 18 lessons. A creative activity uses candy and other food...

Students develop their abilities to solve problems both in school and in a variety of situations similar to that they have encountered in life. They define the term ecosystem in nature by comparing them to familiar organizational...

Is that drawn to scale? Capture the artistry of geometry using the ratio method to create dilations. Mathematicians use a center and ratio to create a scaled drawing. They then use a ruler and protractor to verify measurements. 

It's time for your young artists to shine! Learners examine images to determine possible similarity transformations. They then provide a sequence of transformations that map one image to the next, or give an explanation why it is...

What is the relationship between a hemisphere, a cone, and a cylinder? Using Cavalieri's Principle, the class determines that the sum of the volume of a hemisphere and a cone with the same radius and height equals the volume of a...

Can segments be considered perpendicular if they don't intersect? Learners look at nonintersecting segments on the coordinate plane and make conclusions about the lines that contain those segments. They determine if they are...

Pupils learn to solve square root equations and rationalize denominators. Problems include those with extraneous solutions. 

Don't give your classes the third degree. Use radians instead! While working with degrees, learners find that they are not efficient and explore radians as an alternative. They convert between the two measures and use radians with the...

Without data, all you are is another person with an opinion. Show learners the power of statistics and probability in making conclusions and predictions. Using two-way frequency tables, learners determine independence by analyzing...

Time to experiment with mathematics! Learners study experimental design and how randomization applies. They emphasize the difference between random selection and random assignment and how both are important to the validation of the...

We know that sample data varies — it's time to quantify that variability! After calculating a sample mean, pupils calculate the margin of error. They repeat the process with a greater number of sample means and compare the results.

Pupils analyze group data to identify significant differences. They use simulation to create their own random assignment data for comparison. 

Using patty paper, classes determine that only one triangle is possible when given two specific angle measures and a side length. As the 10th instructional activity in the series of 29, young math scholars add these criteria to those...

Given a diagram of connected or overlapping triangles, individuals must find congruent parts using various properties. Pictures include reflexive sides and vertical angles amongst the marked congruent parts.

What do cats and human DNA have in common? The second lesson of a series focuses on the mapping of mammal genomes. Scholars learn about the structure of DNA as they compare the chromosomes of humans and felines.

The tension builds as learners experiment in your classroom. The 17th installment in a 24-part series has scholars investigate the concept of surface tension. After discovering characteristics of surface tension, they add a compound...

Survival of the fittest isn't just for the movies! A five-part lesson explores several different species with known adaptations and analyzes them for their survival strategies. Using both video and research data, scholars draw...

Students are introduced to new vocabulary. Then they are to guess what the words mean without using a dictionary. They organize words into a graphic organizer.

Ready, set, go! Individuals practice converting rational numbers between fractions, decimals, and percents. A speed game has teams match the three forms of rational numbers on a number line.

Simplifying is radical, dude! After reviewing how to simplify square roots of whole numbers, scholars consider how to simplify square roots of algebraic monomials. Also taken under consideration is how to simplify cube roots of whole...

Mail me a postcard. Individuals design a postcard to show what Meg Lowman from The Most Beautiful Roof in the World might have written to her friends at home. They then continue to work on writing a science journal entry.

Learners get the opportunity to investigate the concept of data collecting. They explore how to tally and read a bar graph. Vocabulary about data is also be included. At the end of the lesson, individual students collect data independently.

Students use the internet to research the production of manuscripts and books. Using this information, they create a research book full of tips to research effectively. They share their new book with the class after organizing the material.

Young readers select a book from a provided list to use as the basis for an intensive class study of Holocaust novels. After completing their novels, groups create a multimedia presentation highlighting the elements of literature...
