## Area And Circumference Of A Circle Problem Solving Worksheet

Area and circumference of a circle often gives our students their first taste of geometry during the year. Also, it seems like students see formulas for the first time when learning this topic. That means that we have to teach the idea of using formulas to them as well as how to find the area and circumference of a circle. Even though that can feel daunting, though, the great thing about circles and geometry is that they lend themselves to application pretty easily. We definitely have the opportunity to let students see area and circumference in a hands-on way.

Measure circular objects to explore the relationship between circumference and diameter of a circle in order to discover the ratio , Pi. Have students work in partners or small groups. Students should measure the circumference and the diameter of the objects that they brought to school. Students will likely have little trouble measuring the diameter, although they may have some difficulty identifying the exact middle of an object. To measure the circumference , students will likely need some assistance. An effective method for measuring the circumference is to wrap a string around the object and then measure the string, or to use flexible measuring tapes.

## Exploring Pi

Using reasoning skills, students will understand how the formulas for circumference and area of a circle are derived. Students will use a wide array of skills such as deductive reasoning, finding patterns, using algebra, modeling and transformation of an object. The teacher ensures student success through direct instruction, investigation and collaborative group work. The teacher will present the material with an investigative approach using material contained within the attached files. The lesson is designed to be very hands-on and group oriented. Students are tasked to look for a specific element pi and for developing patterns that they can make sense of.

## Area of a Circle by Cutting into Sectors

Discover the area formula of circles by separating into congruent shapes and using their understanding of other polygons. As an Introductory activity, distribute the Fraction Circles Activity Sheet download from Materials section to student pairs. Have students highlight each part of a circle they know and recognize using a different color. Be sure students are identifying the radius and the diameter. Students should be able to calculate radius from diameter and diameter from radius.

This area of a circle activity is a great way for kids to better understand the formula. Read our full disclosure policy here. Oftentimes in math class, students are simply given a formula and told to just use it. Hopefully you can agree with me that, no , it will not.

Tell students that they will be exploring Archimedes' method for estimating the value of pi, a mathematical constant that is the ratio of a circle's circumference the distance around a circle to its diameter the distance across a circle through its center. The Greek symbol for pi is pi. Organize students into groups. Provide copies of the "Archimedes' Recipe for Pi" student handout and other materials to each group.
