Your students will “hop their way” into understanding place value with this fun and active game! In this lesson, they will learn that changing the order of the digits in a number changes its value.
Students will be able to identify different place value digits within a number.
Introduction (10 minutes)
- Spread out the place value blocks so the students can see (ones, tens, hundreds, and thousands).
- Explain to the students that they will be exploring place value.
- Explain to the students that place value is the amount each digit in a number represents.
- Call on a few students to come up to the front of the classroom to show various one, two, three, and four digit numbers using the place value blocks.
- Ask a student to come up with a two-digit number.
- On the board, write the number, but purposely put the digit that should be in the ones place in the tens and the digit that should be in the tens in the ones.
- Ask the students to stand up if they believe you wrote the number correctly.
- Call on a student to explain the mistake you made using the place value blocks.
- Explain to the students that when they switch the digits around in a number, the value of the number changes.
- Explain to the students that they will play “place value hop” to change a number's value by changing the placement of the digits in the number.
Explicit Instruction/Teacher Modeling (10 minutes)
- Pick out four numbers using the large number cards. Hold up the number cards so the students can see them.
- Read the number aloud.
- Explain that you will change around the digits to make the biggest number.
- When you’ve created the biggest number, create the smallest number.
Guided Practice/Interactive Modeling (15 minutes)
- Call four students up to the board.
- Get out the number cards and spread them out.
- Ask each student to pick up a number.
- Ask the students to stand in a line holding their numbers up so the class can see them.
- Ask a student to read the number aloud.
- Next, ask the students to see if they can make the biggest number possible by changing the order of the digits in the number. Allow the students time to discuss which students need to change places.
- Ask the students to “hop” as they trade places with a peer.
- Repeat the process, but ask students to make the smallest possible number.
- Call up groups of four students at a time until everyone in the class has had a chance to participate.
Independent Working Time (15 minutes)
- Gather students together, and pass out the Place Value Hop worksheet.
- Read the directions to the students, and tell them that they may begin.
- Enrichment: For a challenge, have students create their own number cards with partners and groups and see who can make the biggest four and five digit numbers!
- Support: Students who need extra help can use the Place Value Hop Support sheet. This is a differentiated version that only gives students two-digit numbers to work with.

Assessment (5 minutes)
- During the lesson, rotate around the classroom to check on groups and observe students. Make note of struggling students and students who are easily able to solve the problems.
- Ask students to turn in their sheets so you can check for understanding.
Review and Closing (5 minutes)
- Ask one of the students to explain in her own words what she learned today.
- Write a final set of four digits on the board.
- Call on a student to come up and write the biggest number and the smallest number that can be made using the digits.
