If you chose to make a polygon shape, your spinner should have a section for each side. Spinners made from hexagons can have six sections, for example. A circular spinner can have between two and eight sections. A greater number of sections will make the spinner more difficult to read. I know the spinner has a mass of 0.0519 kg and a radius of around 3.7 cm. Putting this into the approximation, I get a calculated value of 7.1 x 10-5 kg*m 2---close enough. Also, it should be ... Example: The spinner below is spun two times. The probability of landing on the 1 is 0.25. The probability of landing on the 2 is 0.75. Let x be the sum of the two spins.

If students do not suggest it, tell them the mathematical theory of probability says that the more times you spin a spinner, the closer the results will match the theoretical distribution. The next day, have students again cut apart their numbers, discard blank squares, and add to the class strip of 1s, 2s and 3s.
When the arrow is spun once on this spinner, a 1 or a 2 or a 3 can be scored depending on the colour the arrow lands on. Aimee is going to spin the arrow twice.
