Great for Pi Day! Also great for any time of year your students need practice finding diameter, radius, circumference and area of circles.
I designed this product as a relay race with students racing to find the circle that matches the given circumference, area, radius or diameter. However, I have also included ideas for using this as a scavenger hunt where students find circular objects around the room or as a set of 8 task cards.
This activity also requires measuring with whole, half and quarter inch measurements however the product is easy to adapt to different levels by simply pre-labeling the circles with measurements or providing formulas if necessary.
