Over a pizza dinner, RJ and Mia discuss how to use a circle or pie graph to represent data. After viewing, data analysts can use a Test Yourself feature to assess their own understanding. This is ideal for use in a flipped classroom lesson.

It's time to show what you know! Individuals first review finding the area of polygons using the formulas from parallelograms to regular polygons. They then brush up on finding the area and circumference of circles, as well as reviewing...

It's a piece of pizza! Pupils learn about a sector of a circle as a slice of the circle and determine how to find its area. Scholars continue to find out how to calculate the segment of a circle based on the sector's area. At the end,...

Gobble up a slice of the task. Scholars first consider the area of a whole pizza, half a pizza, and a quarter of a pizza. They then consider other central angles and develop a formula for the area of any sector of a circle.

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...

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...

It's the skill where fractions and circles must work together. A thorough lesson models the process of finding the area of a sector using a radius and angle. The narrator extends instruction to include finding a radius of a circle from a...

It's all about the portion size! Given a photo of a pumpkin pie, learners work to determine the number of calories that are missing. Supplemental information provides the angle of the piece that is missing as well as the nutritional...

Cutting the cheese isn't a joke. Scholars observe a wedge of cheese and must determine how to cut it in half horizontally. They apply their knowledge of sectors to determine the most accurate way to slice the cheese.

Find a slice of pi. The presentation talks through the process of finding the area of sectors and segments of circles. While working examples, the installment of an extensive geometry playlist uses the process to show the formulas for...

Explore the volume of solids with a real-life connection. Learners calculate the volume of a deep-dish slice of pizza to determine its price. They model the slice as a part of a cylinder and create a formula for calculating the cost.

What do skateboarding and baked goods have in common with math? You can use them to connect half-pipe ramps and cakes to arcs and sectors. Pupils compare the lengths of three different ramp options of a skate park. They calculate the...

Don't go around and around, help your class determine amounts around and in a circle with a video that connects circumference to the perimeter or the distance around an object. The resource includes 14 questions dealing with circles and...

Viewers learn how to apply proportional reasoning to find area of sectors and arc lengths with a video that starts off explaining how to find the areas of circle sectors and the lengths of arcs. Scholars then practice solving problems...

Going around in circles trying to find a resource on sectors of circles? Here is an activity where pupils first complete an assessment task to determine the areas and perimeters of sectors of circles. They then participate in an activity...

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...

Before you can do anything with circles, you need to know the parts of the circle. Viewers of a short video see how to label relevant information about a circle. The resource covers radius, diameter, circumference, chord, tangent, arc,...

It's not a sector, it's not a triangle, it's just a segment. Viewers of a short YouTube video learn how to calculate the area of a segment. They see how to determine the area of the sector and then subtract off the area of a triangle to...

Double the pizza? What a great deal! Young pizza enthusiasts investigate two different coupons, one that doubles the radius and one that doubles the sector angle of a slice. They determine which coupon is the better deal.

In this online math worksheet, students solve word problems the involve circles. This excellent resource allows the students to check their answers, and to get "hints" should they run into difficulties. A terrific teaching tool!

Students examine the four sectors of society. They identify each business in the community as either a nonprofit, for-profit or governmental business. They discuss the importance of each sector to the community.
