Look at the following number sentences:
20+300+7= 237
20+300+ 7 < 238
Is this correct? Why or why not?
No, it is incorrect because the expanded form is in the wrong order and added incorrectly. It should say 300+20+7= 327.
327 > 238
Here are some numbers that can be made with the digits 3, 5, and 8:
358, 385, 538, 583, 835, 853
Jenny thinks 835 is the greatest of them all. Is she correct? Why or why not?
No she is not because 835 and 853 both have the largest number in the hundreds spot, but 853 is greater because it has a 5 in the tens spot and 835 only has a 3 in the tens spot. The 5 stands for 50 and the 3 stands for 30 and 50 is greater than 30, so 853 is the greatest number.
Put the following numbers in order from least to greatest:
321, 132, 123, 213, 312, 231
