LESSON 3 Close Enough!
That Is Close Enough
Three schools are getting together for a sports day at Bessie Coleman School. There are 247 students from Bessie Coleman School, 457 from Clark School, and 322 from Lincoln School. Sam, a third-grader at Bessie Coleman School, says he thinks there are about 1050 students at the sports day.
- Do you think Sam's estimate is reasonable? Show or tell how you decided.
Carla, Levi, and Sara each thought about Sam's estimate. They each used an estimation strategy to see if it was reasonable.
Carla said, “I added the hundreds first.”
Levi said, “I thought of it a different way.”
Sara said, “It is easier for me to round to hundreds.”
