Students explore the layers of the Earth and the dynamic changes that they cause on Earth's surface. Volcanoes and earthquakes become the focus of the activity as the Oregon State quarter and its Crater Lake images are linked to the topic.

Eighth graders participate in a lesson plan that is intended to review topics of Algebra.They investigate the concepts of percent and solve problems. Students also solve equations that involve percent of change.

In this language arts learning exercise, students practice oral speaking by agreeing or disagreeing with a controversial sentence. Students read the sentence on each card in front of the group and tell how they feel about the statement...

Prove the Law of Sines two ways. The ninth segment in a series of 16 introduces the Law of Sines to help the class find lengths of sides in oblique triangles. Pupils develop a proof of the Law of Sines by drawing an altitude and a second...

Are e-marketing or traditional marketing promotions more effective in business? Scholars explore the topic as they discuss and debate e-commerce. To finish, they develop marketing plans to demonstrate learning. 

Five activities encourage scholars to look inside, get in touch with their emotions, and express their feelings appropriately. Stories set the stage for feeling identification and in-depth discussions. Role play and the act of miming...

It's time to refine writing and word choice. Learners work on Part 1 of their end of unit assessment by creating an essay titled What Makes a Hurricane a Natural Disaster? They use glossaries and graphic organizers from previous...

In the first installment of a 21-part module, scholars build on previous understandings of probability to develop the multiplication rule for independent and dependent events. They use the rule to solve contextual problems.

Discover how to calculate the expected value of a random variable. In the seventh installment of a 21-part module, young mathematicians develop the formula for expected value. They connect this concept the dot product of vectors.

Enhance the reading experience with a set of lessons designed to improve textual analysis. Seventh graders use guiding questions to read both informational text and literature closely in the first part of the unit. Next, they work on...

Classmates apply midpoint concepts by leapfrogging around the complex plane. The 12th lesson in a 32 segment unit, asks pupils to apply distances and midpoints in relationship to two complex numbers. The class develops a formula to find...

Develop probability distributions from simulations. Young mathematicians use simulations to collect data. They use the data to draw graphs of probability distributions for the random variable in question.

Knowing the addition formulas allows for the calculations of double and half formulas. The fourth installment of 16 has the class use the addition formula to develop the double angle trigonometric formulas. Using the double formula,...

Build on the understanding of finding angles using trigonometric ratios. Pupils develop the definitions of inverse trigonometric functions by restricting their domains in the 13th lesson of a 16-part series. They use inverse functional...

Build understanding of theme with an activity designed for The Cay and the Common Core. Small groups or pairs use graphic organizers to determine themes, find and record related details from the text, and formulate theme statements. In...

How many of the pupils at your school think selling soda would be a good idea? Show learners how to develop a study to answer questions like these! The lesson explores the meaning of a population versus a sample and how to interpret the...

Build upon the Pythagorean Theorem with the Law of Cosines. The 10th part of a 16-part series introduces the Law of Cosines. Class members use the the geometric representation of the Pythagorean Theorem to develop a proof of the Law of...

What do you do when you don't think you have enough information? You look for another way to do the problem! Pupils combine what they know about finding the area of a triangle and trigonometry to determine triangle area when they don't...

Here's a series of five exercises designed to help teens develop  the team work skills needed in the 21st century classroom and workplace. 

Challenge the class to prove that the dilation properties always hold. The instructional activity develops an informal proof of the properties of dilations through a discussion. Two of the proofs are verified with each class member...

To commute or not to commute, that is the question. The 26th segment in a 32-segment lesson focuses on the effect of performing one transformation after another one. The pupils develop the procedure in order to multiply two 2 X 2...

Learn how to determine a probability distribution. In the ninth installment of a 21-part module, future mathematicians use theoretical probabilities to develop probability distributions for a random variable. They then use these...

What if you don't have theoretical probabilities with which to create probability distributions? The 11th installment of a 21-part module has scholars collecting data through a survey. The results of the survey provide empirical data to...

Discover how mathematics can be useful in comparing strategies. Scholars develop probability distributions for situations and calculate expected value. They use their results to identify the best strategy for the situation.
