    If 1 ten frame is full and 1 ten frame is not: we could have 11,12,13,14,15,16,17,18 or 19, but not 20.

  2. Jade says 10 is the largest and 11 is the smallest

  3. Largest number is 19
    Smallest is 11

  4. 19 is the biggest
    11 is the smallest

  5. Smallest should be 10. Because there is no indication that any markers are on the second 10-frame. This same question is on here somewhere but with one 10-frame using its rows. This does cause a contradiction.
