Common Core Standards:

CCSS.MATH.CONTENT.4.MD.C.5: Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement:

·         CCSS.MATH.CONTENT.4.MD.C.5.A: An angle is measured with reference to a circle with its center at the common endpoint of the rays, by considering the fraction of the circular arc between the points where the two rays intersect the circle. An angle that turns through 1/360 of a circle is called a "one-degree angle," and can be used to measure angles.

Targeted Needs of Student:

Exploring percentages, relating knowledge of circles to probability, division of a circle, angles of a circle

Goal:

To provide students with a way to see and work with probability  

Materials Needed:

1.      Protractors

2.      Paper Clips

3.      Brads

4.      Three different color markers

5.      Notebook paper

Explanation/Summary:

Students will make this spinner in their notebook with the instructions to design a sinner that has a 30% probability of spinning red, a 40% probability of spinning green. They will use a protractor to divide the circle into ten equal slices and then they will place a paperclip through the middle using a brad to hold it down. Then the students will spin the spinner ten times to proof that the probability is correct.
