Sofía Marín · p. 3 · Cornell summary
The radius goes from the center to the edge and the diameter is half of the radius. The circumference is the outline and you find it with π times the diameter. The area is the inside: π times the radius squared. If the radius is 5, the circumference is 10π.
1 2Great order of ideas. Check how radius and diameter are related.
“The diameter is twice the radius (d = 2r). Review p. 2.”
“Great example with radius 5 → 10π. Can you find the area too?”

Create a short quiz on circles and probability for Math 7 with questions from the Play and Learn bank. Then turn it into a sports game.
Done, I prepared a draft:
- Quiz with 4 bank questions (Math 7 · 7.DPSR & 7.MGSR).
- Same content ready as Basketball shootout or any of 65 templates.
- Category: Quizzes & games (30%).
To review: explanations come from the bank; read them before assigning.
45 seconds per question, and let's also play it live with the class.
Done: 45 s timer, 3 lives. Live mode is ready with code 482 913 — nothing is assigned until you approve it.
