Students hone their teamwork skills and play off each other's writing strengths as they participate in prewriting activities for a story to be written collaboratively by the whole class.

Investigate collisions on an air hockey table. Set up your own experiments: vary the number of discs, masses and initial conditions. Is momentum conserved? Is kinetic energy conserved? Vary the elasticity and see what happens.

The purpose of this task is to help students understand the connection between counting and cardinality. Thus, oral counting and recording the number in digit form are the most important aspects of this activity. However, teachers can extend this by making a bar graph about how many students are wearing the color each day.

In small groups and class discussion, students share knowledge about Christopher Columbus and his voyages, learn about the impact of Columbus, and consider some ecological and political results of the encounter.

This classroom activity for high school students uses a collection of Hubble Space Telescope images of galaxies in the Coma Cluster. Students study galaxy classification and the evolution of galaxies in dense clustered environments.

Making Evidence-Based Claims ELA/Literacy Units empower students with a critical reading and writing skill at the heart of the Common Core: making evidence-based claims about complex texts. These units are part of the Developing Core Proficiencies Program. This unit develops students' €abilities to make evidence-based claims through activities based on a close reading of the Commencement Address Steve Jobs delivered at Stanford University on June, 2005.

The goal of the Listening and Learning Strand is for students to acquire language competence through listening, specifically building a rich vocabulary, and broad knowledge in history and science by being exposed to carefully selected, sequenced, and coherent read_alouds. The 9 units (or domains) provide lessons (including images and texts), as well as instructional objectives, core vocabulary, and assessment materials. The domain topics include: Nursery Rhymes and Fables; Five Senses; Stories; Plants; Farms; Kings and Queens; Seasons and Weather; Colonial Towns; and Taking Care of the Earth.

This textbook follows California Language Arts Standards for grades 9-12 to provide a generalized understanding of composition and to serve as a supplementary aid to high school English teachers.

The purpose of this task is for students to compare fractions using common numerators and common denominators and to recognize equivalent fractions.

This lesson focuses on comparing and ordering fractions in ways that encourage deeper understanding of’ ‘number sense’ by supporting learners to consider different techniques to order and compare fractions with different numerators and denominators. The three techniques covered in this lesson are those used to compare fractions with like numerators or denominators, unlike numerators or denominators and by comparing to a 1/2 benchmark. Emphasis are placed on the two latter techniques. Activities and practice exercises involve real-world problems including sales discounts, cooking measurements and school score reports.

This task is meant to address a common error that students make, namely, that they represent fractions with different wholes when they need to compare them. This task is meant to generate classroom discussion related to comparing fractions. Particularly important is that students understand that when you compare fractions, you implicitly always have the same whole.

The purpose of this task is to foster a classroom discussion that will highlight the difference between multiplicative and additive reasoning.

The purpose of this task is to assess studentsŐ understanding of multiplicative and additive reasoning.

The CyberSquad proves that the area of Hacker's land is equal to the area of Judge Trudy's land in this video segment from Cyberchase.

The purpose of this task is to help develop students' understanding of addition of fractions; it is intended as an instructional task.

The focus of this task is on understanding that fractions, in an explicit context, are fractions of a specific whole. In this problem there are three different wholes: the medium pizza, the large pizza, and the two pizzas taken together.

The Comparison and Contrast Guide outlines the characteristics of the genre and provides direct instruction on the methods of organizing, gathering ideas, and writing comparison and contrast essays.

An interactive applet and associated web page that demonstrate the concept of complementary angles (angles that add to 90 degrees). The applet shows two angles. You can drag the endpoints of each angle and the other angle changes so that they always add to 90 degrees. They are drawn in such a way that it is visually obvious that together they form a right angle, although they are separate on the page. The angle measure readouts can be turned off for class discussions. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.

FreeReading is an open source instructional program that helps educators teach early literacy. Because it is open source, it represents the collective wisdom of a wide community of teachers and researchers. FreeReading contains Comprehension Activities, a page of activities to address important comprehension skills and strategies.
