Circles

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...

Four fabulous worksheets are included in this resource, all having to do with the measurement of angles. On the first, anglers will use a protractor to determine the degrees of 10 different angles. An arc is drawn on each. On the second,...

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...

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.

Visual models support young mathematicians with exploring equivalent fractions. Starting with a quick warm-up problem, children go on to work through a series of guiding practice problems before working with a partner identifying and...

Visual models support young mathematicians as they deepen their fractional number sense in this elementary math lesson plan. Using fraction circle manipulatives, children explore basic unit fractions as they develop the fundamental...

Fascinating discussion regarding the origin of Pi accompanies a detailed explanation of how to find the circumference of a circle. Since this is the first installment in a series on circles, the concept of circumference is separated into...

Start an engaging data analysis study with a review of charts and graphs using the linked interactive presentation, which is both hilarious and comprehensive. There are 27 statistics-related vocabulary terms you can use in a word sort....

Fourth and fifth graders identify three types of angles, recognize that angles are measured in degrees, measure angles using protractors or angle rulers. They classify angles as a class, classify angles on pattern blocks, and complete a...

Young scholars figure the diameter and circumference of a circle. In this circles lesson, students break into small groups and work together to find the answers then compare with peer groups. Young scholars then make human circles and...
