LESSON INSTRUCTION
INTRODUCTION
- Begin by asking students what they know about place value and how it relates to numbers.
- Display a number in standard form, such as 456, and ask students to identify the digits and their respective place values.
- Introduce the concept of expanded form and explain that it is a way to write numbers as the sum of their place values.
- Display the same number, 456, in expanded form, such as 400 + 50 + 6, and ask students to identify the place value of each digit.
INSTRUCTION
- Review the concept of place value and its relationship to numbers.
- Define and explain standard form and expanded form to students, using visual aids if necessary.
- Provide an example of converting from standard form to expanded form, such as 2,306 = 2,000 + 300 + 6, and explain the process.
- Provide an example of converting from expanded form to standard form, such as 500 + 80 + 7 = 587, and explain the process.
- Model a few more examples of converting between standard form and expanded form, and have students follow along on their individual whiteboards.
- Discuss common mistakes or misconceptions that students may have when converting between standard form and expanded form, such as forgetting a digit or forgetting to carry over a value.
GUIDED PRACTICE
- Provide students with place value blocks or chips and have them create a number in standard form.
- Have students exchange their number with a partner and convert it to expanded form.
- Walk around the room to observe students' progress and provide support and guidance as needed.
- Have students come back together as a class and share their numbers and the corresponding expanded form.
INDEPENDENT PRACTICE
- Provide students with worksheets containing several problems of converting between standard form and expanded form.
- Encourage students to use the strategies they learned during the instruction and guided practice portions of the lesson.
- Circulate around the room to provide individual support and guidance as needed.
HOMEWORK
- Provide students with additional practice problems for homework, along with a reminder to use the strategies they learned during the lesson.
EXIT TICKET
- Provide each student with an exit card containing a number in standard form or expanded form.
- Instruct students to convert the number to the opposite form.
- Collect the exit cards to assess students' understanding of converting between standard form and expanded form.
ASSESSMENT
- Assess students' understanding of converting between standard form and expanded form by collecting and reviewing their worksheets and exit cards.
- Identify any areas that may require further instruction or support.
CLOSURE
- Recap the main concepts learned in the lesson, including standard form, expanded form, and place value.
- Encourage students to continue practicing converting between standard form and expanded form, and remind them to apply their understanding of place value when doing so.
- Provide positive reinforcement for students' progress and hard work throughout the lesson.
EXTENSION
- For students who have mastered converting between standard form and expanded form, provide them with more challenging problems, such as converting numbers with decimals or converting larger numbers.
- Students can create their own problems and exchange them with a partner to solve.
INTERVENTION
- For students who struggle with place value concepts, provide them with additional hands-on activities, such as using place value blocks or chips.
- For students who need extra support, provide them with additional practice problems and one-on-one guidance during independent practice.
- For students who need additional reinforcement, provide them with visual aids, such as posters or anchor charts, that illustrate the concepts of standard form and expanded form.
VIDEOS

TEACHING TIPS
- Use manipulatives, such as place value blocks, to reinforce the concept of place value.
- Encourage students to explain their thinking and share their strategies with their classmates.
- Provide extra support for students who struggle with place value concepts, such as additional practice problems or one-on-one guidance.
STUDENT MISCONCEPTIONS
- Students may forget to account for all the digits when converting between standard and expanded form.
- Students may confuse the place value of a digit with the actual value of the digit.
- Students may have difficulty visualizing and understanding the concept of expanded form.
STANDARD
Common Core Standard:
3.NBT.A.1 - Use place value understanding to round whole numbers to the nearest 10 or 100.
