Math Addition Worksheets

1. Customizable Difficulty Levels

Create math addition worksheets tailored to different learning levels with a variety of number ranges:

Each range includes multiple digit combinations. For example, within 100 you can generate problems like 1-digit plus 1-digit, 1-digit plus 2-digit, 2-digit plus 1-digit, or 2-digit plus 2-digit.

2. Support for Decimals and Multiples of 10, 100, and 1000

Easily generate addition problems with decimals (1-decimal, 2-decimal) or round numbers such as multiples of 10, 100, or 1000.

3. Compatible with Multiple Paper Sizes

All worksheets are formatted for easy printing on A4 and US Letter paper—ideal for classrooms, homework, or tutoring sessions.

4. Randomized and Repeatable Problems

Each worksheet is generated randomly. You can choose whether to allow repeated problems or ensure every one is unique.

2. Choose Answer Range

This generator allows you to create math addition problems based on answer ranges such as:

Choose the appropriate range to match the student's level. Each range includes multiple problem structures such as single-digit plus double-digit, or two-digit plus two-digit problems.

3. Choose Problem Structure

Problem structure defines how numbers are formed in the addition problem. For example, within 100, you may find combinations like 1-digit plus 2-digit or 2-digit plus 2-digit problems. Below is a breakdown by answer range:

4. Choose Problem Constraints

Math constraints refine the type of numbers used. You can choose to include decimals (1 or 2 decimal places), or restrict to round numbers such as multiples of 10, 100, or 1000.

5. Choose Operation Rules

Choose whether to allow regrouping in addition problems. "Without Regrouping" ensures all problems are generated without regrouping — ideal for early learners.

6. Allow Duplicates

Choose whether duplicate problems are allowed in your printable math worksheet. Choosing "No Duplicates" ensures all generated problems are unique.

7. Choose Number of Pages

Choose how many pages of worksheets you want to generate. Each page includes a fixed number of problems and is automatically laid out in a clean, print-friendly format. This option lets you control the total number of practice questions.

8. Choose Paper Type

Choose the Paper type compatible with your printer. We support A4 (210 × 297 mm) and US Letter (8.5 × 11 inches), the two most commonly used paper sizes in homes and schools around the world. This ensures your worksheets are ready to print and use without formatting issues.
