### Description

This hands-on cooperative activity is a great way to introduce parts of a circle.

How can I use this product?

Using simple paper clips, partners work together and discover the ratios between radius, circumference, and diameter by seeing patterns. Fun, creative activity that also encourages teamwork and cooperation. It's a good math center as well.

What is included?

1 pdf file with:

* 2 pages of complete instructions

* 1 page of a student log sheet

While the Common Core Standards don’t directly mention radius & diameter for the primary grades, this activity will directly help students generate and analyze patterns.

Common Core Standards:

Generate and analyze patterns

4.OA.5. Generate a number or shape pattern that follows a given rule. Identify apparent features of the pattern that were not explicit in the rule itself. For example, given the rule “Add 3” and the starting number 1, generate terms in the resulting sequence and observe that the terms appear to alternate between odd and even numbers. Explain informally why the numbers will continue to alternate in this way.

7.G.4 Solve real-life and mathematical problems involving angle measure, area, surface area, and volume. Know the formulas for the area and circumference of a circle and use them to solve problems; give an informal derivation of the relationship between the circumference and area of a circle.
