Eileen didn't have a 6 times one; she had 5 x 3.
Anyway, I think hers was a good method. You want 5 x 3. (Ok, maybe you'd just say 15, but suppose you were unsure or didn't remember.) The paint balls will be distracting, so you don't want to keep a running total, unassisted, in memory. But you have 5 fingers on a hand, making it easy to keep track if you use them Then you just need to count by 3s, moving to a new finger each time And she
could count by 3s.
