10. Stretch Your Thinking Luanne estimates the sum of 39 + 15 is about
40 + 15, or 55. Jacob estimates the sum of 39 + 15 is about 40 + 20,
or 60. Which estimate is closer to the exact sum? Explain.
Possible answer: Luanne’s estimate is closer to the exact sum. Luanne
did not round 15 because it’s easy to add to 40. Jacob rounded 15 to
the nearest ten, which is 20. The sum of 39 + 15 is 54. Luanne’s
estimate of 55 is closer.
