LESSON INTRODUCTION:

  • The Area of a circle, as we all know, is the space that takes up the inside of a circle. The CIRCUMFERENCE, is a term that describes the perimeter of a circle. It’s the length it takes to travel all the way around the outside of a circle. To calculate these, we need a couple of FORMULAS and they will make things easier for us to calculate both area and circumference. To calculate the area or circumference of a circle, you will need to know the RADIUS. The radius of a circle is the length from the center of the circle to any point on the circumference. It is always exactly HALF of the DIAMETER (the entire width across a circle) .

PROJECT-BASED LEARNING SCENARIO: (Who students will be and what they will accomplish)

  • Your aunt is an Urban and Civil Engineer in your community.  She has recruited you as her apprentice. She has recently received a contract from the state to expand and redesign some of the neighborhoods in your area. 

    She explains that some of the buildings in the world aren’t square or rectangle in shape; they are round! She says, “the town or city you live in is no different. To properly design a variety of different buildings for the community, we need to understand how much space they take up! Round buildings too!”

    “By learning about the circumference (the perimeter of round shapes) and area of circles, we can better plan our newly designed neighborhoods to include these buildings that are round too. It makes for towns and neighborhoods that have a variety of different buildings, which looks unique,” she mentions. 

    As her apprentice, she has given you the responsibility of counting the number of round structures and buildings in your community and determining their circumferences and area. 

    Your job is to learn as much as you can about the circumference and area of circles, so you can help her make the most diverse and interesting neighborhood possible!
