In this task using a number line, students must partition the interval between 0 and 1 into eighths.
Material Type: Activity/Lab
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.
Material Type: Activity/Lab
The purpose of this task is for students to compare fractions using common numerators and common denominators and to recognize equivalent fractions.
Material Type: Activity/Lab
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.
Material Type: Homework/Assignment, Lesson Plan
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.
Material Type: Activity/Lab
The purpose of this task is to foster a classroom discussion that will highlight the difference between multiplicative and additive reasoning.
Material Type: Activity/Lab
The purpose of this task is to assess studentsŐ understanding of multiplicative and additive reasoning.
Material Type: Activity/Lab
These word problems involve multiplicative comparison.
Material Type: Activity/Lab
The purpose of this task is to help develop students' understanding of addition of fractions; it is intended as an instructional task.

A demonstration of the distributive property of multiplication using models. This video is less than 15 minutes.
Material Type: Lecture
This task suggests ways to incorporate counting circles into classroom activities.
Material Type: Activity/Lab
This unit uses roller coaster design as a method of teaching students about energy types, energy conservation, and the design process. At the end of this Unit, students critical thinking and problem-solving skills should be strengthened.

CK-12’s Life Science delivers a full course of study in the life sciences for the middle school student, relating an understanding of the history, disciplines, tools, and modern techniques of science to the exploration of cell biology, genetics, evolution, prokaryotes, protists, fungi, plants, the animal kingdom, the human body, and ecology. This digital textbook was reviewed for its alignment with California content standards.
Material Type: Textbook
In this quick and simple activity, learners explore how the distribution of the mass of an object determines the position of its center of gravity, its angular momentum, and your ability to balance it. Learners discover it is easier to balance a wooden dowel on the tip of their fingers when a lump of clay is near the top of the stick. Use this activity to introduce learners to rotational inertia.

Series of videos that can be used in an AP Biology Labs class created by Paul Anderson- Bozeman Science
Material Type: Lecture
Use this hands-on activity to demonstrate rotational inertia, rotational speed, angular momentum, and velocity. Students build at least two simple spinners to conduct experiments with different mass distributions and shapes, as they strive to design and build the spinner that spins the longest.
