Multi-Arm Layouts
📋 What it is
A spinner can branch into several arms, so a layout may have three or four open ends to add at once.
🗣️ Coach says
Once a spinner opens arms, the open-end total is a sum of MORE numbers. A four-arm layout might show 6, 6 (a double), 2, and 5 — that is 6+6+2+5 = 19. More arms means more chances to hit a multiple of 5, and more math to track. Slow down and add every tip.
🧠 Memory hook
Count ALL arms. More open ends = a bigger sum and more ways to score — but easier to miscount.
😂 Giggle
Why are dominoes such good mathematicians?
They add up their open ends every single turn!
😲 Whoa!
Chickenfoot forces a THREE-armed foot off every double, so the open-end total there can jump quickly.
✅ Quick check: A four-arm layout shows open ends 5, 5, 3, and 2. What is the total, and does it score in All Fives?
Say your answer out loud first — then reveal.
15 — yes, it scores 15 (a multiple of 5).
Add every open arm: 5+5+3+2 = 15, which is divisible by 5.
🧪 Try it! (2 minutes)
Draw a spinner with 3 arms, put a number on each, and add them. Change one arm and re-add.
