In this activity students compare an eighteenth-century print of a slave ship and a table of data about the voyages of the slave ship to draw facts and make inferences about the transatlantic slave trade. This activity was designed for the Smartboard, but it can be completed without a Smartboard.

This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important aspects of the task and its potential use.

This task combines two skills from domain G-C: making use of the relationship between a tangent segment to a circle and the radius touching that tangent segment (G-C.2), and computing lengths of circular arcs given the radii and central angles (G-C.5). It also requires students to create additional structure within the given problem, producing and solving a right triangle to compute the required central angles (G-SRT.8).

Tá Falado includes 46 podcast lessons on the pronunciation and grammar of Portuguese, specifically designed to help those who already speak Spanish. The lessons are built around Portuguese dialogs that are repeated in Spanish, providing a direct comparison of the two languages. All lessons include downloadable PDF files with the transcripts and notes, mp3 audio files, and blog discussions. Additionally all of the dialogs present cultural scenarios that illustrate differences between North American and Brazilian culture.

What is economics and why should you spend your time learning it? After all, there are other disciplines you could be studying, and other ways you could be spending your time. As the Bring it Home feature just mentioned, making choices is at the heart of what economists study, and your decision to take this course is as much an economic decision as anything else.

Economics is probably not what you think it is. It is not primarily about money or finance. It is not primarily about business. It is not mathematics. What is it then? It is both a subject area and a way of viewing the world.

U-Lab: Leading Profound Innovation for a More Sustainable World is an interactive and experiential class about leading profound innovation for pioneering a more sustainable economy and society. The class is organized around personal reflection practices, relational practices, and societal practices. It focuses on the intertwined relationship between the evolution of capitalism, multi-stakeholder innovation, and presencing.

This textbook is not intended to be an exhaustive treatise; rather, it is intended to be far more useful than that for beginning tax law students by equipping the novice not merely with unmoored detail but rather with a rich blueprint that illuminates the deeper structural framework on which that detail hangs (sometimes crookedly). Chapter 1 outlines the conceptual meaning of the term “income” for uniquely tax purposes (as opposed to financial accounting or trust law purposes, for example) and examines the Internal Revenue Code provisions that translate this larger conceptual construct into positive law. Chapter 2 explores various forms of consumption taxation because the modern Internal Revenue Code is best perceived as a hybrid income-consumption tax that also contains many provisions—for wise or unwise nontax policy reasons—that are inconsistent with both forms of taxation. Chapter 3 then provides students with the story of how we got to where we are today, important context about the distribution of the tax burden, the budget, and economic trends, as well as material on ethical debates, economic theories, and politics as they affect taxation.

Armed with this larger blueprint, students are then in a much better position to see how the myriad pieces that follow throughout the remaining 19 chapters fit into this bigger picture, whether comfortably or uncomfortably. For example, they are in a better position to appreciate how applying the income tax rules for debt to a debt-financed investment afforded more favorable consumption tax treatment creates tax arbitrage problems. Congress and the courts then must combat these tax shelter opportunities (sometimes ineffectively) with both statutory and common law weapons. Stated another way, students are in a better position to appreciate how the tax system can sometimes be used to generate (or combat) unfair and economically inefficient rent-seeking behavior.

This task presents an opportunity to explore a more general and non-algebraic view of functions.

U.S. History is designed to meet the scope and sequence requirements of most introductory courses. The text provides a balanced approach to U.S. history, considering the people, events, and ideas that have shaped the United States from both the top down (politics, economics, diplomacy) and bottom up (eyewitness accounts, lived experience). U.S. History covers key forces that form the American experience, with particular attention to issues of race, class, and gender.
