In this unit, students learn about the form and function of the human heart through lecture, research and dissection. Following the steps of the Legacy Cycle, students brainstorm, research, design and present viable solutions to various heart conditions as presented through a unit challenge. Additionally, students study how heart valves work and investigate how faulty valves can be replaced with new ones through advancements in engineering and technology. This unit demonstrates to students how and why the heart is such a powerful organ in our bodies

In the story, Alexander, Who Used to Be Rich Last Sunday, Alexander receives a dollar from his grandparents that he plans to save, but he spends it all, a little at a time. In this lesson, students count by 2s to fill a container with 100 pennies. They are asked whether 100 pennies is the same amount of money as one dollar. They listen to the story, and as Alexander spends his money, students come up and remove the correct number of pennies from a container. At the end of the story, students are again asked if 100 pennies is the same amount of money as one dollar. Students discuss the choices that Alexander made and give advice on how he could save his money to reach his goal of buying a walkie-talkie.

CK-12 Foundation's Basic Algebra FlexBook is an introduction to the algebraic topics of functions, equations, and graphs for middle-school and high-school students.

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.

In this module, students reconnect with and deepen their understanding of statistics and probability concepts first introduced in Grades 6, 7, and 8. Students develop a set of tools for understanding and interpreting variability in data, and begin to make more informed decisions from data. They work with data distributions of various shapes, centers, and spreads. Students build on their experience with bivariate quantitative data from Grade 8. This module sets the stage for more extensive work with sampling and inference in later grades.

In earlier modules, students analyze the process of solving equations and developing fluency in writing, interpreting, and translating between various forms of linear equations (Module 1) and linear and exponential functions (Module 3). These experiences combined with modeling with data (Module 2), set the stage for Module 4. Here students continue to interpret expressions, create equations, rewrite equations and functions in different but equivalent forms, and graph and interpret functions, but this time using polynomial functions, and more specifically quadratic functions, as well as square root and cube root functions.

In this lesson, students will become familiar with glaciers, how they form, move, and shape the land.

In this lesson, students analyze the allusions, slang, and literary analogies used in "Raymond's Run" by Toni Cade Bambara. To extend understanding, they will then write their own allusions and analogies.

Students will explore the individual’s responsibility to society and the ways in which all humans are interconnected through their reading of excerpts from several texts, letters, poems, short stories and articles.

In this unit, students begin their exploration of animals and animal adaptations by reading a collection of nonfiction texts.

The National Humanities Center presents collections of primary resources compatible with the Common Core State Standards - historical documents, literary texts, and works of art - thematically organized with notes and discussion questions. Topics discussed in this unit include the following: Becoming Modern: America in the 1920s: City & Town. It looks at the divide between country and city, and the ongoing growth of cities that became evident in the 1920 census. Includes a collection of commentaries, and selected pieces from authors.

Topics discussed in this unit include the following: Becoming Modern: America in the 1920s: Black & White. Even as racial pride advanced in the modern world, racial hatred escalated to new extremes. Here we explore the black-white division through commentary, political cartoons, visual art, and musical drama.

Topics discussed in this unit include the following: Becoming Modern: America in the 1920s: Modern Faith. In its myriad forms, the search for "modern faith" in the Twenties reflected two concurrent drives - the need to affirm human goodness, hope, and salvation after the apocalyptic world war, and the struggle to accommodate modernity with traditional and revered belief systems. Presents a collection of commentaries on this topic from 1919-1929.
