Understanding 3-digit numbers and their various representations is a crucial skill in early math education. We are excited to introduce a versatile and engaging resource called "Expanded Form," designed for Year 2, Year 3, and Year 4 students. This free resource can be downloaded by clicking the button at the bottom of the page.

Why Use the "Expanded Form" Resource?

The "Expanded Form" resource offers a comprehensive approach to teaching 3-digit numbers by breaking them down into

understandable parts. It can be used as a standalone lesson, a warm-up activity, or a fast finisher task, making it a flexible tool for any math classroom.


How Does the "Expanded Form" Resource Work?

  1. Preparation:

    • Download the "Expanded Form" resource and print out the worksheets. Laminating the sheets allows for repeated use with dry-erase markers, making it a durable addition to your teaching toolkit.

  2. Interactive Learning:

    • In the center of the worksheet, teachers write a 3-digit number in the circle.

    • Students then fill in the surrounding boxes to represent the number in four different ways.


Breakdown of the Worksheet

  1. Hundreds, Tens, and Ones:

    • The first box requires students to write the number in terms of hundreds, tens, and ones. For example, for the number 376, students will write 3 hundreds, 7 tens, and 6 ones.

  2. Place Value:

    • In the second box, students write the value of each digit. For 376, this would be 3 = 300, 7 = 70, and 6 = 6.

  3. Expanded Form:

    • The third box has students write the number in expanded form. For 376, they will write 300 + 70 + 6 = 376.

  4. MAB Blocks Representation:

    • The last box features pictures of MAB (Multibase Arithmetic Blocks). Students circle or color the blocks to visually represent the number.


Benefits of the "Expanded Form" Resource

  • Comprehensive Understanding:

    • By breaking down 3-digit numbers into smaller components, students gain a deeper understanding of place value and number representation.

  • Versatile Use:

    • The resource can be used in various settings, including standalone lessons, math warm-ups, and as a fast finisher activity.

  • Engagement:

    • The interactive nature of the worksheet keeps students engaged and actively participating in their learning process.

  • Visual Learning:

    • The inclusion of MAB blocks helps visual learners grasp the concept of place value more effectively.


Using the "Expanded Form" Resource in Your Classroom

  1. Stand-Alone Lesson:

    • Use the worksheet as a complete lesson on place value and number representation. Guide students through each box to ensure they understand how to break down 3-digit numbers.

  2. Math Warm-Up:

    • Incorporate the worksheet into your daily math warm-up routine. This helps reinforce place value concepts regularly.

  3. Fast Finisher Activity:

    • Provide the worksheet to students who finish their work early. This ensures they remain engaged and continue to practice important math skills.

  4. Homework Assignment:

    • Assign the worksheet as homework to reinforce the day's lesson and provide additional practice at home.

The "Expanded Form" resource is an invaluable tool for teaching 3-digit numbers to Year 2, Year 3, and Year 4 students. By breaking down numbers into hundreds, tens, and ones, students gain a comprehensive understanding of place value and number representation.
