Round a given decimal to any place using place value understanding and the vertical number line.

In this lesson, students extend their understanding of rounding whole numbers to rounding decimal numbers to any place by, using place value charts and vertical number lines. Students start by rounding whole numbers to the nearest tens and hundreds. Then they round a given decimal to the nearest whole and tenths. For example, students strategically decompose 1.57 to round to the nearest whole and nearest tenth. Finally, students round a given decimal to the nearest ten, one, tenths, and hundredths.
