Product Description
This product is an excellent tool to use when teaching your students about circles. The PDF file contains two 8 ½ x 11 charts: Parts of a Circle and Circumference Formula, as well as a seven slide/page process explaining the formula for the area of a circle.

How can I use this product?
They can be used on a anchor chart, bulletin board, as well as put inside a journal. As well as a class discussion on the formula of the are of a circle.

The formula for the area of a circle is based upon dividing the circle into even wedges, and then laying them to form a parallelogram. This process can also be printed and posted, or stepped through (by displaying each page in front of your class) as a hands on activity, with students cutting circles and laying them out themselves. And with you asking questions along the way to guide them to figuring out the formula, your students will have a good understanding. This leads to using base times height, which is the formula most students are used to, when learning area for rectangles. This is an explicit step-by-step process chart that also includes an example for each step.

Though the charts are in full color, they are simple in design that they will print out great in black and white or grey scale.
