The circumference of a circle is the distance around the edge of the circle. It is similar to the perimeter of other shapes, such as rectangles or squares, but specifically refers to the distance around a circle.

The formula for finding the circumference of a circle is:

C = 2πr

where C is the circumference, π (pi) is a constant approximately equal to 3.14159, and r is the radius of the circle.

**Understand the concept:**Make sure you understand that the circumference is the distance around the circle, and how it is different from the area of the circle.**Learn the formula:**Memorize the formula C = 2πr, and understand what each symbol represents.**Practice with examples:**Work through practice problems to calculate the circumference of circles with different radii.**Use π (pi):**Understand the significance of π and how it is used in the formula to find the circumference.**Real-life applications:**Look for real-life examples where understanding the circumference of a circle is important, such as in engineering or design.

By understanding the concept of circumference and practicing with the formula, you can become proficient in calculating the distance around a circle.

Grade 6 Curriculum Focal Points (NCTM)

Algebra: Writing, interpreting, and using mathematical expressions and equations

Students write mathematical expressions and equations that correspond to given situations, they evaluate expressions, and they use expressions and formulas to solve problems. They understand that variables represent numbers whose exact values are not yet specified, and they use variables appropriately. Students understand that expressions in different forms can be equivalent, and they can rewrite an expression to represent a quantity in a different way (e.g., to make it more compact or to feature different information). Students know that the solutions of an equation are the values of the variables that make the equation true. They solve simple one-step equations by using number sense, properties of operations, and the idea of maintaining equality on both sides of an equation. They construct and analyze tables (e.g., to show quantities that are in equivalent ratios), and they use equations to describe simple relationships (such as 3x = y) shown in a table.
