Th ink for a moment. Why does it help me to be able to estimate the answer to a problem? For example, how does it help me to know the answer to 52 + 34 is close to 80? Give me a Thumbs Up when you have an idea.

STUDENTS DO: Th ink for a moment. Give a Thumbs Up to volunteer. Selected students share their thinking.
TEACHER DO: Summarize students’ thinking. If no students mention it, explain that having an estimate of the answer can help them see if their real answer is reasonable. For example, if they estimate the answer should be close to 80, but their answer is 65, that should tell them they may have done something wrong.
