Grade 4 Lesson Plan: Writing Multi-Digit Whole Numbers in Standard Form, Word Form, and Expanded Form

Engagement: 1. Begin the lesson by asking students to share examples of numbers they encounter in their daily lives (e.g., phone numbers, prices, addresses). Discuss the importance of being able to read and write numbers accurately. 2. Show a short video clip that demonstrates the significance of writing numbers correctly in different forms. For example, you can use the video “Writing Numbers in Different Forms” from Khan Academy (https://www.khanacademy.org/math/cc-fourth-grade-math/cc-4th-place-value-rounding/cc-4th-writing-numbers-in-different-forms/v/writing-numbers-in-different-forms).

Materials: - Whiteboard or chart paper - Markers - Number cards (prepared in advance) - Worksheets (links provided below) - Pencils

Lesson Outline: 1. Introduction (5 minutes) - Review the importance of writing numbers accurately in different forms. - Explain that today’s lesson will focus on writing multi-digit whole numbers in standard form, word form, and expanded form.

1. Standard Form (10 minutes)
   • Write a multi-digit number (e.g., 345) on the board.
   • Ask students to identify the place value of each digit.
   • Explain that standard form is the most common way to write numbers and involves writing the digits in their respective place values.
   • Model how to write the number in standard form (345).
2. Word Form (15 minutes)
   • Write the same number (345) on the board.
   • Ask students to think about how they would read this number aloud.
   • Discuss the importance of using correct terminology (e.g., hundreds, tens, ones).
   • Model how to write the number in word form (three hundred forty-five).
   • Provide additional examples and ask students to write the numbers in word form on their whiteboards or notebooks.
3. Expanded Form (15 minutes)
   • Write the same number (345) on the board.
   • Explain that expanded form involves breaking down the number into its place values.
   • Model how to write the number in expanded form (300 + 40 + 5).
   • Provide additional examples and ask students to write the numbers in expanded form on their whiteboards or notebooks.

Questioning: - What is the difference between standard form, word form, and expanded form? - How can we determine the place value of each digit in a multi-digit number? - Can you give an example of a number written in standard form, word form, and expanded form?

Assessment: - Observe students’ participation and engagement during class discussions and activities. - Review students’ written responses on their whiteboards or notebooks. - Use the provided worksheet resources for formal assessment (links provided below).

Differentiation: - For students who need additional support, provide manipulatives (e.g., base-10 blocks) to help them visualize and understand place value. - Pair students with a partner for peer support during activities. - Provide extra practice worksheets for students who grasp the concept quickly.

Extension Activities: 1. Challenge students to create their own multi-digit numbers and write them in standard form, word form, and expanded form. 2. Have students work in pairs to create a “Number Museum” display, where they showcase different numbers written in various forms. 3. Assign a project where students research and present real-life examples of numbers written in standard, word, and expanded forms (e.g., population statistics, sports scores).
