Circles are the foundation of many geometric concepts and extensions - a point that is thoroughly driven home in this extensive unit. Fundamental properties of circles are investigated (including sector area, angle measure, and...

Circles, circles, everywhere! Pupils learn all about circles, central angles, inscribed angles, circle theorems, arc length, area of sectors, and radian measure using a set of 12 lessons. They then discover volume formulas through...

Create trigonometric functions from circles. The first lesson of the module begins by finding coordinates along a circular path created by a Ferris Wheel. As the lessons progress, pupils graph trigonometric functions and relate them to...

All the 2-D and 3-D measurement work you need is in one location. Divided into three sections, the geometry lesson plans consist of visualization of three dimensions, classifying geometric figures, and finding surface area and volume....

Take young mathematicians on an exploration of the world of 3-D geometry with this seven-lesson unit. After first defining the terms perimeter, area, and volume and how they apply to the real world, students continue on...

Win the war of the worlds! Scholars solve a variety of problems related to an alien invasion. They determine where spaceships have landed on a coordinate map, devise a plan to avoid the aliens, observe the aliens, and break a code to...

Your learners connect the new concepts of transformations in the coordinate plane to their previous knowledge using the solid vocabulary development in this unit. Like a foreign language, mathematics has its own set of vocabulary terms...

Who wants to go fast? The answer? Your sixth-grade science superstars! The complete resource offers the ultimate, all-inclusive playbook for mastering the important concepts of speed versus time; distance versus time; and how...

Why is voting important? A social studies unit presents a non-partisan approach to the importance of voting, to voting laws and procedures, and to resources that voters need to become informed voters.

Trace the links between a variety of math concepts in this far-reaching unit. Ideas that seem very different on the outset (like the distance formula and rigid transformations) come together in very natural and logical ways. This...

Solids come in many shapes and sizes. Using geometry, scholars create two-dimensional cross-sections of various three-dimensional objects. They develop the lesson further by finding the volume of solids. The module then shifts...

Your learners combine their knowledge of real and imaginary numbers and matrices in an activity containing thirty lessons, two assessments (mid-module and end module), and their corresponding rubrics. Centered on complex numbers and...

How can one person change the world? Scholars research and analyze the topic of world hunger. Using video clips, parodies, and primary source evidence, they uncover a current campaign to end world hunger. Collaborative groups openly...

A narrated screencast which demonstrates how to measure circular motion. [4:41]

Watch this descriptive tutorial, and learn how to figure the rotational motion of an object. [5:23]

Use the fact that the arc measures of a circle must sum to 360 degrees to find missing arc measures. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Practice measuring angles using a circle protractor, solve problems about angles as part of a circle. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

A video lesson that introduces the components of circular motion. Understand that any objects that rotates around a point is in circular motion. Video also explores how to measure how far an object has rotated. Video gives equation for...

Demonstrates how to calculate the area of two-dimensional shapes using formulas. Covers parallelogram, triangle, trapezoid, and circle. Includes a video modeling how to find the area of a circle and a triangle. [0:59]

Read about Gross Domestic Product (GDP) and how we measure it.

Determine the missing angle measures of quadrilaterals inscribed in circles.

The mathematics session investigates arc length and radian measure. The tutorial consists of class notes, calculator tips, examples, and practice problems with solutions. The teacher resource includes an activity that discovers radian...

This lesson will demonstrate how to find the area and radius of a circle when given the sector area and central angle measure. It is 2 of 8 in the series titled "Sector Area of a Circle."
