Jane took the "scientific approach" that it looked like there were are least 80 little coloured pieces. Zoë persisted that the measurement be exact. 1..2..3..4..(Zoë's lips silently mimicking Mommy's count) at around 50, Jane declared that based on how many were left on the plate, there were likely 80 as she had said.
