Math Message – Lesson 1-3 Ravi wants to know the total number of students that go to his school. The school website says about 860 students. The school newsletter says about 900 students. The principal then tells Ravi that the school has exactly 856 students. How did the website get “about 860”? How did the newsletter get “about 900”? Be prepared to explain how you know.
