Two students both say that if you spin two spinners 100 times, they should get the same number of red-red combinations. But one spinner has more red. Can they both be right?
Describe a moment where your prediction matched the outcome — and/or where it didn’t.
Why can knowing expected outcomes be powerful in real life.
Write/draw/narrate a reflection titled: “Why Math Can Predict the Future”

Math Talk:

Have a conversation about this image. Be curious. Be creative. Can you see in different ways?

What do you notice about the numbers and patterns? How do you see? How and what can you count? What chances are there to roll a certain sum? From a group of 36 students, what chances are there to receive a pair of yellow dice?
