  1. Bronze

    678,489,346,290,110 and 109.

    Silver

    It is incorrect because 111 is supposed to be at the start of the number 223 and 436 then move 436 to the end finally put 223 in between 111 and 436 .

    Gold

    Dora is correct because when you count in the 100s column there is 600 , if you count in the 10s column there is 0 tens and if you count in the 1s column there is 7 all together the total is 607 .Jack just put the 7 ones into the 10s column .

    Platinum

    I don’t agree because if you put the 1 from the one column in to the 10s column the total will be 920.

  2. 109 110 290 396 489 678
    Silver
    no because the 3rd one is the smallest.
    Gold
    Dora is correct because there are no tens.
    Platinum
    no because they should be all be in the 100s column.

  3. 109,110,290,346,489,678
    Bronze
    Silver
    No because the first one is supposed to go in the middle .
    Gold
    Dora is correct because the place value shows 607. Jack is not correct because I think he got jumbled up with the tens and ones

  4. Silver
    111
    223
    436
    111 is the smallest number 223 is the second smallest number 436 is the biggest number.
    Gold
    Dora is correct because there’s no tens in the table but jack is incorrect because he think that there’s no tens

  5. Bronze – 678,489,346,290,110,109
    Silver – No 111,233,436
    Gold – dora is correct because the chart shows 607
    Platinum – no you can make 910

    678
    489
    346
    290

    109.

    Silver
    The first two should be swapped.

    Gold:
    Dora is correct as there are six 100s and seven ones.

    Platinum:
    I do not agree because 999 is a greater number than 800+10+1=811.

  7. Bronze:
    Descending order:
    678,489,346,290,110 and 109.

    Silver:

    No its not because the middle has more hundred tens and ones than the first one.

    Gold:
    I agree with Dora because I would count the place value chart.

    platinum:
    No it isn’t because: the counters in the 100’s column make 800 but you can add another counter to make 900 which is also a 3 digit number.

  8. Bronze
    678 489 346 290 110 109
    Silver
    No because it’s going to small to biggest to smallest
    Gold
    Dora is right because there 6 in the 100s and there is 0 in the 10s and 7 in the 1s.

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

    Silver
    The last one is supose to be first, the first one is supose to be second and the middle one is suppose to be last.

    Gold
    Jack is wrong but Dora is correct because there are only six 100s and seven ones.

    Platinum
    No, I do not agree because 999 is the longest 3 digit number but 800+10+1=811.

  10. Bronze:
    678,489,346,290,110 and 109.
    Sliver:
    No it is not correct because the smallest number is 111 and the greatest number is 436.
    Gold:

  11. Bronze
    109,110,290,346,489,678.
    Silver
    This is wrong because 111 is the smaller than 223 and 436.
    Gold
    Dora is correct because there are 600 in 100 column,0 in 10 column and 7 in 1 column.

    • Well done Ariyan 👍.
      What number will I have if I put 6 counters in the 100 column, 8 counters in the 10 column and 5 counters in the 1 column?
      Have go at the platinum challenge in confident you can do it.

  12. Bronze:
    109,110,290,346, 678,
    Silver:
    No this is not the correct order because 111 should be first,223 second and 436 last.
    Gold:
    Dora is correct and Jack is not because if you look at the 100’s column their is 6, in the 10’s column there is 0 but if you look at 1’s column there is 7, making 607.

    I also did my did the challenge in my homework book.

    incorrect because they swap the greatest number.

    111,223,436.
    Because it said from smallest to biggest so 111 is smaller than 223 this is smaller than 436.
    Gold
    I think Dora is correct because she said 607 Jack is roang because he thought that the ones were tens.

    ♤The first biggest number 436 and then it’s 223 then finally it’s 111.
    Gold
    ♡I agree with dora
    Because on the place value chart it has 6hundreds and 0 tens and 7 ones meaning the number is 607 and Dora has written that the answer 607 which is same on the place value meanwhile jack has written 670 but it’s not the correct answer as the place value chart its shows 607 so therefore I agree with Dora.
