Quilting is not only beautiful and unique—it is a mathematical art. Show your classes how to design a quilting block while practicing area and circumference of circles. Scholars create a star from a square and then find the circumference and area. They make comparisons to the ratio of the area and the size of the original square.

Instructional Ideas

• Have pupils cut out different sizes of squares using the design shown; use the different sizes to make the area and circumference comparisons
• Encourage learners to create their own designs using circles and squares; use these designs to calculate area and circumference

Classroom Considerations

• Requires knowledge of area and circumference of circles

Pros

• Uses a creative approach to practicing circle formulas
• Questions require learners to explain their approach and solutions

Cons

• None
