 * = How should Harry arrange the cards to make the largest number? =
 * = Explain how you know that this is the largest number he can make. (Use correct math vocabulary terms in your explanation) =

2 goes first because it he lowest number then 4 because it is the next highest number then 7 because it is the next highest number then 9 because it is the next highest number that is how I would put them in order and the other way to do it is 9 comes first because it is the next highest number and next is the 7 and then it is the 4 and next is the 2 now all the numbers are in order and the number it makes is 9 thousand and 7 hundred and 42 the other way is 2 thousand and 4 hundred and 79 that is the way i do it the number would be 9,742 that is my answer for that one the other way for the one that i did backwerds is 2,479 that is my answer-james tyler johnson


 * =He should use the highest number first which is 9. Next he should use the next highest number which is 7. Then he needs to use the third highest number which is 4. Last he needs to use the number left over which is 2. The number made is 9,742. I know this is the way to do it because like 2,479 wouldn't be as high as 9,742 because in the first place 9,000 is greater than 2,000. - Caitlyn=
