Circles

Further your instruction on geometrical symmetry with an investigation of circles. Fourth graders come to realize that the lines of symmetry of a circle are infinite.

What does this pie chart mean? Once scholars can analyze a circle graph on a basic level (i.e. "Most people prefer cats"), it's time to delve deeper into it. They examine two graphs here, and are given the total number of participants...

Examine the origin and application of pi in five different levels. The five lessons in the resource begin with an analysis of the relationship between the radius and circumference of a circle. The following lessons lead learners through...

Use this fraction circles template that represents a whole, halves, thirds, fourths, fifths, sixths, eighths, and twelfths to visually reinforce children's understanding of fractions.

For this circle graphs worksheet, students solve and complete 8 different problems that include word problems referring to two different circle graphs shown. First, they follow the directions for each problem and complete the table that...

Your young mathematiciaans collaboratively brainstorm the geometric properties of a circle in this vocabulary rich, geometry lesson plan. Step by step a plethora of properties and shapes emerge as learners fold their circles to create...

Understanding the basic of circles is as easy as pi. The resource introduces the definition of a circle along with its dimensions, circumference, diameter, and radius. Using graphics, the video shows the approximation of pi and how to...

Put pi to work. The video provides the formulas for the circumference and area of circles. Using the formulas, the presenter shows how to distinguish the two using units. The discussion leads to the second formula for finding the...

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.

Come full circle with a lesson on angles. A noteworthy video describes how to calculate the measures of missing angles in a diagram. It goes through several examples in which the sum of the angles is always a full circle, or 360 degrees.
