Twelve chapters cover a multitude of math concepts found in the Common Core standards for sixth grade. Each title provides a brief explanation of what you will find inside the chapter—concepts from which you can click on and learn more...

How can you place a rectangular tile around a pipe? Scholars first use a model of a kitchen sink cabinet to take measurements. Using a compass and their knowledge of circles, they then cut out a circle from a piece of poster board (which...

Crime doesn't pay, but everyone can learn from it. Learners consider different situations involving mischief at a school, such as stink bombs and rockets, and analyze them using mathematics. They must apply trigonometry, quadratic...

Create a geometric playground. Pupils work through a performance task to demonstrate their ability to use geometric concepts to solve everyday problems. The accompanying engineering design lessons show teachers how the assessment works...

Learn about the orbit of the International Space Station directly from an astronaut on the International Space Station! Young scholars hear about the shape and path of orbits from a NASA astronaut in the video lesson from a larger...

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....

Sometimes it's how you ask the question that counts. The sixth installment of nine from the Smarter Balanced Claim 1 Slideshow series presents a set of 13 questions to assess understanding of angle relationships as well as area and...

Unravel the mystery behind the infamous number pi. Scholars complete a series of activities that explores where pi comes from, its digits and estimation strategies. Pupils should be ready to measure, calculate, and look for patterns to...

Pi day is both delicious and informative! Play a short video on Pi Day to explain the basics behind both the holiday and the infinite number.

Dang, it's a word problem! Pupils address a variety of word problems that involve knowledge of proportions and geometric topics. The General Certificate of Secondary Education review problems require determining costs based on area...

Circumference and diameter differ by just a factor of pi. A short video shows viewers how to calculate circumference given the diameter. It also gives an example of determining the diameter given the circumference.

Calculating circumference is as easy as pi times diameter. A short video explains how to measure pie tins using the diameter. It also describes the relationship between diameter and circumference. Using the knowledge, scholars consider...

What a great big skillet you have. The resource introduces the class to the world's largest stainless steel skillet. The class creates a model of the skillet and a typical 12-inch skillet and compares the relative sizes of their areas....

Surround yourself with knowledge about perimeter. An informative video shows viewers how to find the perimeter of a semicircle. It begins with an explanation of calculating the length of the semicircular arc and ends with adding on the...

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...

Scholars ponder the proof relating the center angle and circumference using a demonstrative video. Additional worksheets and textbook practice helps them demonstrate their intellect.

Take a trip back in time to examine angular velocity. Using the revolutions per minute, learners calculate the speed of a point on a 33 record. They compare the speed of a point on the edge of the record to the speed of a point closer to...

Model a bicycle chain with circles and tangent lines. Given the dimensions of the sprocket wheels, young scholars calculate the length of the chain that surrounds them. A second task has learners write a function for the length of a...

Planning a party of 45 guests may be more complicated than it would seem.  Learners must design the space in accordance with these constraints about the space available in the room. They need to calculate area, circumference, and linear...

Gotta catch them all—no learner left behind! Young scholars must predict the length of time it takes a phone attached to a fan to travel five kilometers given the radius and rotations versus time data. Why would you attach a phone to a...

It's hard to envision what 39 billion plastic bottles look like. Brita claims that the US uses that number of plastic bottles each year! If that's not enough to get your attention, figure out how many times 39 billion water bottles can...

Keep playing with those old toy cars! Pupils estimate the number of toy cars in an art installation. The only information they receive is a picture showing the toy cars arranged in concentric rings and the diameter of the overall...

All work and no play makes for a boring classroom! Bring back memories by analyzing the patterns of a tether ball. Given the dimensions of the ball, pole, and rope, young scholars must determine how many times the ball will wrap around...

There's a formula for that. An educational video shows viewers how to apply geometry formulas to solve problems. It covers the formulas for the circumference of a circle, volume of a cone, and the Pythagorean Theorem.
