Halloween Math Activities: Probability Lesson Plan
In third grade, probability is a popular subject, but in this activity you can triple the enjoyment and use it as a Halloween tie-in, . You will need a spinner, a checklist, paper, and crayons. Most classrooms will have spinners that can easily be modified for this lesson, or you can make your own.
To make your own spinners:
1. Draw a circle (or have students draw this using a compass).
2. Divide the circle in half.
3. Leave one half untouched, but break the other half into two equal parts.
4. Leave one of the fourths untouched, but break the other fourth into two equal parts.
To complete your spinner, or modify existing supplies:
1. Label the largest portion with the number 3. (If you are modifying, just put a piece of duct tape over the center and draw a 3 on the tape using marker.)
2. Label the second biggest portion with the number 1.
3. Label the last two, equal-sized, portions with the numbers 2 and 4.
4. If a spinner is needed, use a paper clip, with a pencil tip held at the center of the circle to keep the spinner in place.
