Get your students moving as they learn how to round whole numbers. In this lesson your students will use number lines and kinesthetic movement to practice rounding numbers to the nearest ten or hundred.
Students will be able to round whole numbers to the nearest ten or hundred.
Introduction
(7 minutes)
Lay out a piece of masking tape on the floor, labeled like a number line with numbers 0-30 (write 0, 10, 20, and 30 in red for an easy visual reference).
Invite students to gather near the number line. Then invite one student to stand on a number (i.e. 17) and instruct them to jump to the nearest ten.
Point out that the student jumped to a higher number (20).
Repeat with a few more students and numbers (i.e. 11, 6, 2, 28).
Explain, "Today we are going to learn how to round whole numbers to the nearest ten or hundred, using number lines to help us."
