The documents included in this lesson come from The North Carolina Experience collection of Documenting the American South and specifically focus on African Americans and race relations in the early 20th century. The lesson juxtaposes accounts that relate to both the positive improvements of black society and arguments against advancement. Combined, these primary sources and the accompanying lesson plan could be used as a Document Based Question (DBQ) in an advanced US history or African American history course.

This lesson looks at the natural resources that drew businesses to Alabama. Students will explore the adapted 1820 letter from Mason and Dexter in Cahaba, Alabama to Richards and Simmons in Cumberland, Rhode Island. Students will explain ideas within this historical text based on specific information presented in this primary source. This lesson can be used as a stand alone or can follow A Natural Attraction: The Natural Resources of Alabama During the Early Nineteenth Century . This lesson was created in partnership with the Alabama Department of Archives and History.

In this lesson, students will work in small groups to examine a letter describing the environment of Alabama and identify reasons which might have encouraged settlers to move to Alabama in the early nineteenth century. Students will choose an interesting attraction of Alabama mentioned in the letter and design a postage stamp around that attraction. This lesson was created in partnership with the Alabama Department of Archives and History.

In this lesson, students will learn about the executive branch of government at the state level, especially related to the first governors of the state of Alabama. Their impact on the development of Alabama and Alabama's role in the United States will be discussed. Students will use research and note taking skills to gather information on an early governor. Then students will participate in jigsaw groups to share their information, discuss the importance of each governor, similarities, and impact. Finally, students will discuss the role of governor and how governors have an impact on the state and the impact these men had in Alabama and in other states. This lesson was created in partnership with the Alabama Department of Archives and History.

Students will read a description of the pine barrens by Basil Hall and analyze the text by using the 3-2-1 strategy. Students will discuss the life and work of Basil Hall, including his travels and journaling in North America. They will observe how a camera lucida functions and debate whether using a camera lucida is "cheating" in art. Next, students will venture outside to create a sketch of their environment while appropriately utilizing materials. They will compare and contrast their products to the sketches of Basil Hall and critique each other's work. This lesson was created in partnership with the Alabama Department of Archives and History.

"Students connect polynomial arithmetic to computations with whole numbers and integers.  Students learn that the arithmetic of rational expressions is governed by the same rules as the arithmetic of rational numbers.  This unit helps students see connections between solutions to polynomial equations, zeros of polynomials, and graphs of polynomial functions.  Polynomial equations are solved over the set of complex numbers, leading to a beginning understanding of the fundamental theorem of algebra.  Application and modeling problems connect multiple representations and include both real world and purely mathematical situations.

Module 2 builds on students' previous work with units and with functions from Algebra I, and with trigonometric ratios and circles from high school Geometry. The heart of the module is the study of precise definitions of sine and cosine (as well as tangent and the co-functions) using transformational geometry from high school Geometry. This precision leads to a discussion of a mathematically natural unit of rotational measure, a radian, and students begin to build fluency with the values of the trigonometric functions in terms of radians. Students graph sinusoidal and other trigonometric functions, and use the graphs to help in modeling and discovering properties of trigonometric functions. The study of the properties culminates in the proof of the Pythagorean identity and other trigonometric identities.

"In this module, students synthesize and generalize what they have learned about a variety of function families.  They extend the domain of exponential functions to the entire real line (N-RN.A.1) and then extend their work with these functions to include solving exponential equations with logarithms (F-LE.A.4).  They explore (with appropriate tools) the effects of transformations on graphs of exponential and logarithmic functions.  They notice that the transformations on a graph of a logarithmic function relate to the logarithmic properties (F-BF.B.3).  Students identify appropriate types of functions to model a situation.  They adjust parameters to improve the model, and they compare models by analyzing appropriateness of fit and making judgments about the domain over which a model is a good fit.  The description of modeling as, “the process of choosing and using mathematics and statistics to analyze empirical situations, to understand them better, and to make decisions,” is at the heart of this module.  In particular, through repeated opportunities in working through the modeling cycle (see page 61 of the CCLS), students acquire the insight that the same mathematical or statistical structure can sometimes model seemingly different situations.
