Lesson Narrative
Previously, students extended their knowledge of rounding to the nearest thousand, ten-thousand, and hundred-thousand. They began to generalize strategies for rounding any number within 1,000,000 to any place. In this lesson, students practice rounding numbers and interpret the rounded numbers in context to solve problems. In doing so, they practice reasoning quantitatively and abstractly (MP2). Students also learn the benefits and limitations of rounding numbers when solving problems.
