Predict From a Spinner

Start with Make Predictions From Probability, where the probability is given in a table. Move to Predict From a Spinner and Predict From Survey Results, then use Is the Prediction Reasonable as a check.

Find a spinner probability, then predict the number of spins, like blue on 8 equal parts in 80 spins. The directions on the page read: Spinner parts are equal, and letters name the colors. Find the probability of the event as a fraction in simplest form. Then predict how many times it happens. The page opens with a worked example, and an answer key is included.

Yes, both. We made it for 6th Grade probability, and the page works the same whether it lands on a kitchen table or a center rotation. At home, most families go through it together and talk the answers out loud, and that talking is where most of the learning happens with make predictions. In class it runs well as independent work while you pull a small group. Print one copy or thirty, whichever the day needs.

Multiply the probability by the number of tries. A number cube lands on 6 with a probability of 1/6, so in 60 rolls you would predict 10 sixes.

Write the survey result as a fraction of the students asked, then multiply by the larger group. If 12 of 30 students pick art, predict 12/30 x 700 = 280 of 700 students.

No. A prediction is the expected number, and real results can be a little higher or lower. On Is the Prediction Reasonable, a prediction within 2 of the expected number counts as reasonable.

Yes. All 5 worksheets in this group have answer keys.
