Students will use place value understanding to round multi-digit whole numbers to any place.

Lesson

Introduction (5 minutes)

• Before beginning this lesson, review place value with students. Ensure that they know the ones, tens, hundreds, thousands, and ten thousands places.
• Ask students if they know what rounding is and how to do it.
• Take volunteers to explain it in their own words. Define rounding as altering a number to make it less concise but more convenient.
• Explain to students that today they are going to use place values to round numbers to a given place value.

Explicit Instruction/Teacher Modeling (10 minutes)

• Show students the Rounding to a Given Place Value video.
• Explain to students that you have a strategy for rounding to a given place value, too.
• Review your strategy with students: Find the place, look next door, 5 or more raise the score, 4 or less let it rest, To the right: all zeros, all right!
• Now use the strategy to round a few numbers chosen by you.
• Leave the strategy on the board and have students copy it down in a journal or on a piece of paper.

Guided Practice/Interactive Modeling (10 minutes)

• Pass out the Round 'Em Up worksheet.
• Allow students to work in pairs or small groups to complete the worksheet.
• Advise students to use the strategy to round each number to the place value as written in the instructions.
• You may have to do one from each section to get students started.
• Take the last two or three minutes to go over the answers and address any concerns.

Independent Working Time (20 minutes)

• Pass out the Let’s Go Rounding! worksheet.
• Advise student they will work alone to complete the independent practice.
• If students get stuck, remind them to use the strategy.
• Take the last two or three minutes to go over the answers and address any concerns.

Extend

Differentiation

• Enrichment: Advanced students can use the Rounding to Whole Numbers worksheet to incorporate rounding with decimals to the nearest whole number.
• Support: Students who are struggling can use a place value chart or draw a place value chart for each number to help them identify the place value and round up or down as directed.

Review

Assessment (15 minutes)

• Pass out the Rounding Numbers worksheet which will be used as the assessment.
• Advise students to show that they can round to any given place value.
• Tell them the strategy still applies regardless of the requested place value.

Review and Closing (5 minutes)

• Review the strategy with students.
• Make sure that they all know it and how to use it.
• Put up a large six-digit number and have students round to the nearest hundred thousand.
