Students extend their computational work to include fractions and decimals, adding and subtracting numbers in those forms in this unit before moving to multiplication and division in subsequent units.

In this unit, students will become familiar with fables and trickster tales from different cultural traditions and will see how stories change when transferred orally between generations and cultures. They will learn how both types of folktales employ various animals in different ways to portray human strengths and weaknesses and to pass down wisdom from one generation to the next. Use the following lessons to introduce students to world folklore and to explore how folktales convey the perspectives of different world cultures.

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

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.

CK-12 Algebra Explorations is a hands-on series of activities that guides students from Pre-K to Grade 7 through algebraic concepts.

CK-12 Algebra Explorations is a hands-on series of activities that guides students from Pre-K to Grade 7 through algebraic concepts.

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.

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

This lesson extends over several class periods. Students analyze the claim, grounds, warrants, qualifiers and counterclaims in three articles about the American Dream. Students conduct research and find two additional articles about the American Dream. Students then analyze the argument in those articles. Finally, students write their own argument essay about the current state of the American Dream.

The lesson begins with a demonstration introducing students to the force between two current carrying loops, comparing the attraction and repulsion between the loops to that between two magnets. After formal lecture on Ampere's law, students begin to use the concepts to calculate the magnetic field around a loop. This is applied to determine the magnetic field of a toroid, imagining a toroid as a looped solenoid.

Students read three short stories about women; discuss the development of female characters, gender differences, and society' s expectations; and write scripts in which the characters discuss their similarities and differences.

In this lesson students use the Informational Text Analysis Tool to deconstruct the essential elements of informational text. Informational text is more important to teachers than ever before, especially with the rise of the new Core standards. The Library of Congress is an excellent resource for finding and using texts to build students' reading skills.Through a diverse array of classic and contemporary literature as well as challenging informational and primary source texts, students build knowledge, gain insights, explore possibilities, and broaden their perspective.

In this activity, students discover the relationship between an object's mass and the amount of space it takes up (its volume). Students learn about the concept of displacement and how an object can float if it displaces enough water, and the concept of density and its relationship to mass and volume.

In the first of two sequential lessons, students create mobile apps that collect data from an Android device's accelerometer and then store that data to a database. This lesson provides practice with MIT's App Inventor software and culminates with students writing their own apps for measuring acceleration. In the second lesson, students are given an app for an Android device, which measures acceleration. They investigate acceleration by collecting acceleration vs. time data using the accelerometer of a sliding Android device. Then they use the data to create velocity vs. time graphs and approximate the maximum velocity of the device.

Students are introduced to the classification of animals and animal interactions. Students also learn why engineers need to know about animals and how they use that knowledge to design technologies that help other animals and/or humans. This lesson is part of a series of six lessons in which students use their growing understanding of various environments and the engineering design process, to design and create their own model biodome ecosystems.

Drawing upon the online archives of the U.S. Holocaust Museum, this lesson helps students to put the events described by Anne Frank into historical perspective, and also serves as a broad overview of the Nazi conquest of Europe during World War II. After surveying the experiences of various countries under Nazi occupation, the lesson ends with activities related specifically to the Netherlands and Anne Frank.

This lesson concentrates on Anne Frank as a writer. After a look at Anne Frank the adolescent, and a consideration of how the experiences of growing up shaped her composition of the Diary, students explore some of the writing techniques Anne invented for herself and practice those techniques with material drawn from their own lives.

In this problem students are comparing a very small quantity with a very large quantity using the metric system. The metric system is especially convenient when comparing measurements using scientific notations since different units within the system are related by powers of ten.

Students will read and observer ants to discover how ants are the same and different than people.
