When we return to school next week, my students and I will continue to explore the circumference and area of a circle.  We had begun to work on circumference prior to Christmas holidays and my students seem to be grasping the concepts well.  We did a GREAT activity in our math journals (I’ll post that soon) and that helped them to understand Pi, circumference, radius, diameter, and the circumference formula.  We will work on the area of a circle when we return.  After introducing the concept of area through a few math journal activities (more on the next week), we’re going to amalgamate, explore, and review these concepts through math centres.  I’ve created the following math centres to help students apply the skills and concepts they are learning about circles and have some extra practice activities.  Student worksheets are included in this package.

There are five math centres:

  • Reviewing the Circumference and Area of a Circle
  • Circumference Extra Practice
  • Area of a Circle Extra Practice
  • Calculating Radius and Diameter
  • Circumference and Area Word Problems

Students will take part in the following activities:

  • extra practice questions
  • practice using proper problem solving format (record given information from the question, formula, calculations, and final statement)
  • solving word problems
  • working backwards using algebra to determine the radius and diameter when given the area or circumference
  • developing their own word problems to trade and solve with a partner
  • review sheets to aid in recapping and studying
