10th Day: We made a 10 with 10 zeros on it (hole reinforcers).
20th Day: We made a 20 out of circles and put a star sticker on each circle (20 stars total). These will print 2 on a page.
30th Day: We sorted Apple Jacks cereal that Zero the Hero left for us. Then we counted our 30 pieces by 5's and 10's.
