With this free video resource, students will explore the economic way of thinking, and the role incentives play in all our lives through engaging Hollywood production style videos.

Educators can use MRU's videos in a variety of ways, to include “flipping” the classroom, as study aids, supplementary material, concept reinforcement, or even as a full course offering.

In MRU's Principles of Macroeconomics course, we’ll cover fundamental questions such as: Why do some countries grow rich while others remain poor? How important is a country’s banking system — and what happened during the recent financial crisis? How did Zimbabwe end up with an inflation rate that rose into the quadrillions?

We’ll also cover important topics like the Federal Reserve, monetary policy, fiscal policy, the Solow Growth Model, institutional analysis, the “economics of ideas,” and more.

Many of us can remember our first great economics teacher who fundamentally changed how we see the world. At MRU, we try and deliver that experience to millions worldwide through video.

Founded as a nonprofit in 2012 by George Mason University economics professors Tyler Cowen and Alex Tabarrok, MRU is building the world’s largest online library of free economics education videos -- currently weighing in at more than 800 videos.

In MRU's Principles of Microeconomics course, covers fundamental concepts like supply and demand and equilibrium. We also answer questions such as: How are prices determined? What did Adam Smith mean when he said the market process works like an “invisible hand”? How is it that we have access to fresh roses in very cold cities every Valentine’s Day? All key topics are covered to include competition, monopoly, price discrimination, externalities, public goods and more.

There are no prerequisites for this course, and it is accessible to beginners.

This video explains how to create a pictograph from given information. Algebraic problem solving is required.

Overview: Students will explore protein synthesis through several resources, and compare it to DNA replication. This resource assumes that students understand DNA synthesis.

First grade students will be immersed in three different public service announcements. This immersion will help them understand the characteristics of a PSA. After a discussion, the students will create one on either internet safety or being a good digital citizen.

Why do governments exist? One major reason is that they create rules. But what rules are necessary or desirable? That is open to question, and different types of governments have certainly created a wide variety of rules.

This resource contains information which may be used by students for self-directed learning. Teachers may use it to supplement their lessons.

This Flexbook is community contributed through ck12.org. It covers three lessons on the Pythagorean Theorem. 1) Introduction and Determining if the Triangle is a Right Triangle, 2) Finding the Hypotenuse, and 3) Finding a leg. It includes step by step instructions, application problems, and answers (at the end of each lesson). Ck12.org material is downloadable, editable, and accessible offline and online.

This is a short PowerPoint presentation template that I have created for my students to revise and make functional. After spending a day working with the Pythagorean Theorem, I want my students to work in groups to revise this presentation so that it could be used to introduce the Pythagorean Theorem in a classroom setting.

“Rapper” ArtCollect and recycle product wrappers for a “green” art project worthy of good-citizen attention! Students save and trade wrappers to make a collage paper background. Then the background is combined with an introductory printmaking process to create a graphic design.Students choose words and phrases related to their “rapper” collage and cut them from thin foam to create a print plate. Cut-out letters are simply turned backwards onto the plate — no intricate reverse carving into linoleum. “Rapper” Art is an easy process for making posters, book covers and signs in multiples.Grade Levels K-6Note: Instructions and materials based on a class of 25 students. Adjust as needed.

This reading goes over steps to calculate rate of reactions. Calculating rate of reactions can seem a little bit confusing, but hopefully going over this reading you’ll be more confident.

In this lesson, students distinguish between real and fake reading. Students learn and practice metacognition strategies to strengthen comprehension while reading.

In this lesson, students are introduced to text structure through rereading an excerpt from The Most Beautiful Roof in the World. They use a graphic organizer to describe the structure of the excerpt and use a model summary of this excerpt to build on their understanding of effective summaries. Students also read a new section from The Most Beautiful Roof in the World for gist, in preparation for a close reading of an excerpt from this section in the next lesson (RI.5.2, RI.5.4, RI.5.5, RI.5.10, W.5.9b).
In Closing and Assessment A, refer to the Finding the Gist and Unfamiliar Vocabulary: The Most Beautiful Roof in the World: "Out of the Shadow and into the Light (answers, for teacher reference; see supporting materials). Words students are likely to be unfamiliar with have been included in the Unfamiliar Vocabulary column, with accompanying definitions provided in the Meaning column; however, these words may vary based on students.
Students practice their fluency in this lesson by following along and reading silently as the teacher reads The Most Beautiful Roof in the World in Work Time A and by reading this text with a partner in Work Time A and Closing and Assessment A.
The research reading that students complete for homework helps build both their vocabulary and knowledge pertaining to the rainforest, specifically rainforest species and research. By participating in this volume of reading over time, students will develop a wide base of knowledge about the world and the words that help describe and make sense of it. Inviting students to share what they have been learning through independent reading holds them accountable.
In this lesson, the habit of character focus is working to become an effective learner. The characteristic students are reminded of specifically is collaboration, as they work in pairs to compare the graphic organizer.

In this lesson, students consider the unit research question and develop specific categories for research. Then, in small groups, students read texts about how kids have made a difference and take notes using those categories (RI.4.1, W.4.7, W.4.8).
W.4.8 requires students to gather information from print and digital sources. As such, this lesson is designed for students to use internet sources as texts. If the technology necessary for students to complete the reading is unavailable, give them printed copies of possible texts from which to choose. Note that "Protecting Our Planet" is not a website and is provided (see supporting materials).
Students who finish quickly or require an extension can use a search engine to find their own sources.
In this lesson, students focus on working to become effective learners by focusing on a characteristic of their choice as they work in expert groups to begin their research.
