      It is wrong it’s it should be111,223,436.
      Gold
      She has 13 eggs left
      Platinum I disagree because the largest number is 900

    Silver
    Original number sequence from smallest to biggest:
    223,436,110
    This is incorrect because 436 is not smaller than 223 or 110. You could also recheck by using jottings on a piece of paper or whiteboard.

  6. Bronze
    109,110,346,486,678
    Silver
    It’s wrong because the end is supposed to be the first one and the first one should be in the middle and the middle one should be at the end

  10. Bronze 678, 489, 346, 290, 110, 109

    Silver
    No because it’s not in the correct order… 436 is In the middle

    Gold
    Suzie the snake has 19 eggs 5 x 3 = 15 4 x 4 = 16

  11. Bronze
    678, 489, 346, 290, 110, 109

    Silver
    No because the second is at the start, and the greatest is in the middle and the smallest is at the end.

    Gold
    Suzie the snake has 19 eggs because 5 x 3 = 15 and four left over is 19. And 4 x 4 = 16 with 3 left over makes it 19.

    Platinum
    No because 910 is larger than 811. If you put all counters in the hundreds column it becomes 1000, but that is a 4 digit number, so the largest 3 digit number is 910

  12. bronze:
    678,489,346,290,110,109
    silver:
    No because its not in order 436 is in the middle
    Gold:
    4×4=16
    16+3=19
    5×3=15
    15+4=19
    She has 19 eggs
    Platinum:
    No because 811 is not bigger than 1000 however that is a 4 digit number so 911 will be the biggest number.

  13. Bronze

    678, 489, 346, 290, 110, 109

    Silver

    No it’s not correct because it should be 111, 223, 436

    Gold

    Susie has 19 eggs because 4×4=16 and 16+3=19
    5×3=15 and 15+4=19

    Platinum

    No because he made 811 and the biggest number you can make is 990

  14. Bronze:
    678,489,346,290,110,109
    Sliver:
    111,223,436
    Gold:
    When Susie counts in fours-
    4+4+4+4=16 plus 3 left over=19
    When Susie counts in fives- 5+5+5=15 plus 4 left over=19

  15. • Bronze

    678, 489, 346, 290, 110 ,109

    • Silver

    No, because it’s not the correct order.
    The correct order is
    111, 223, 436.

    • Gold

    4+4=8
    8+4=12
    12+4=16
    16+3=19 eggs

    5+5=10
    10+5=15
    15+4=19 eggs

    She has 19 eggs.

    • Platinum

    No, I disagree because, if we move one counter from the ones grid to hundreds grid the new number will be 910 which is bigger than 811. However, if we also move the tens counter the total number will be 1000 which is 4 digits. So the largest 3-digit is 910.

  16. Silver
    The numbers are not ordered from smallest to greatest because 436 is bigger than 223. Also 111 is smaller than 436 so they cannot be smallest to biggest.

    Gold
    Susie has 19 eggs.

    4 8 12 16
    16+ 3 = 19

    5 10 15
    15 + 4 =19
