Cathy may not understand that you look at the neighbor of your number which is seven and anything with the number 4 or less will stay the same. Which would get you 1,200 anything 5 or more you will raise the number which means that the number 1,275 rounded to the nearest hundredth would be 1,300.
The two numbers are very near 7200 and 300. The sum of those is a good estimate of your sum:
... 7200 + 300 = 7500
_____
If you're taught methods of addition that include "make a ten" or "make a hundred", you know you can "borrow" a 1 from 7203 (making it 7202) and loan that 1 to 299 to make it 300. Now, you know your sum is exactly 7202+300 = 7502, with no estimation necessary.
