If your students are working with pi and calculating the areas or circumferences of circles, this activity will give them plenty of practice. Students will use Οr2 to calculate the areas of circles and regions within them. Each model progresses in complexity from simple to advanced. This can be used as an individual or team activity with upper middle school and high school students in regular education or more advanced students at lower grade levels. Students can even create their own circular designs using the included template for a culminating project.

CCSS7.RP.A.2c

Represent proportional relationships by equations. For example, if total cost π΅ is proportional to the number π― of items purchased at a constant price π±, the relationship between the total cost and the number of items can be expressed as π΅ = π±π―.

CCSS7.RP.A.2

Recognize and represent proportional relationships between quantities.

CCSS8.EE.A.2

Use square root and cube root symbols to represent solutions to equations of the form πΉΒ² = π± and πΉΒ³ = π±, where π± is a positive rational number. Evaluate square roots of small perfect squares and cube roots of small perfect cubes. Know that β2 is irrational.

CCSS7.EE.B.4

Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities.

CCSS8.NS.A.2

Use rational approximations of irrational numbers to compare the size of irrational numbers, locate them approximately on a number line diagram, and estimate the value of expressions (e.g., ΟΒ²). For example, by truncating the decimal expansion of β2, show that β2 is between 1 and 2, then between 1.4 and 1.5, and explain how to continue on to get better approximations.
