    Is this correct?

    This is incorrect.

    Explain the reason?

    It is incorrect because it is going medium size to larger to smaller.

    Gold

    Dora is correct because it has 6 100s, no 10’s and 7 1’s which makes it 607.

    Platinum

    Conjecture is incorrect because 991 is the largest can get by adding 10 counter and remaining 3 digit number.

    This is false because it is 100/400/200 when it’s meant to be 100/200/400
    so we need to replace the 400 for a 200.

    Silver This is incorrect because the smallest is at the end not first.

    Gold Dora has given the correct answer.

  7. Ahmed O.

    Bronze:
    678, 489, 346, 290, 110, 109

    Silver:
    No this is not correct. If you move the smallest to the beginning then the it would be correct.

    Gold:
    Dora is correct because there are 6 100’s, 0 10’s and 7 1’s. That makes 607.

    Platinum:
    I disagree because the largest number could be 10×10=1000

    No its not correct because 111 is the smallest so that should be beginning.
    Gold
    Dora is correct
    It is 607
    If it was 670 because there is no tens

    Platinum
    811 is not the biggest number u can make with the counters because you could put all 10 in the hundreds column.and make 1000.

    Silver
    This is false as 436 should be last and 111 First.

    Gold
    Dora is right because there are no 10’s and jack said there are 7 ten’s.

  12. Haarun M.

    This is wrong because the first block is smaller than the second blocks but the second blocks are bigger than the third block.

    It is not correct because the largest number is in the middle.
    Gold:
    Jack is incorrect because Dora said 607, not 670.
