Which number sentence correctly shows how he can round to the nearest 10 to estimate the number of pages he read for this week?

On Friday, 379 tickets were sold for the school

play. On Saturday, 515 tickets were sold. Diana

stated that about 900 total tickets were sold. Is

Diana’s statement about the total tickets sold

true? Use numbers or words to explain why or

why not.

• Diana's statement is true because 379 is about 400 and 515 is about 500. When I add 500 + 400 I get 900.

• Diana's statement is wrong because 379 + 515 = 894 and not 900

• Diana's statement is wrong because she added and she should subtract. 515 is about 500 and 379 is about 400 so 500 - 400 = 100.

• Diana's statement is wrong because she added and she should subtract. 515 - 379 = 136
