Expanded Form Resources

Expanded form is a way to write a number that shows the value of each digit, separated by plus signs and added together to equal the original number. For example, the expanded form of 425 is written as 400 + 20 + 5. This method helps students understand place value by breaking down numbers into the sum of their individual digit values, making it easier to see how each place contributes to the whole number.

Here, you’ll find worksheets, activities, and practice resources that teach children how to write numbers in expanded form, compare standard and expanded forms, and strengthen their grasp of place value concepts. These materials cover a wide range of grade levels, offering problems that move from simple two-digit numbers to larger multi-digit values. By practicing expanded form, students reinforce essential math skills that build a foundation for addition, subtraction, multiplication, and beyond.

Whether you’re a parent, teacher, or student, these resources provide clear explanations and engaging practice to support number sense development. You can also explore related math concepts, such as standard form, word form, and other place value lessons, to create a complete understanding of how numbers work.
