2-Digit Plus 1-Digit Addition Worksheet Grade 1 Free PDF

Addition is one of the first and most important math skills children learn in elementary school. This 2-Digit Plus 1-Digit Addition Worksheet helps Grade 1 students practice adding single-digit numbers to two-digit numbers without regrouping. Through repeated practice, children strengthen their understanding of number relationships while building confidence in basic arithmetic.

The worksheet contains 30 addition problems designed specifically for early learners. Students add a one-digit number to a two-digit number and write the correct sum. These exercises help develop fluency, improve mental math skills, and reinforce place value concepts in a simple and engaging format.

What Students Will Learn

This worksheet focuses on addition without regrouping, allowing students to concentrate on understanding how numbers work together without the added complexity of carrying.

Students will practice:

• Adding 1-digit numbers to 2-digit numbers.
• Building addition fluency.
• Strengthening number sense.
• Recognizing number patterns.
• Improving calculation accuracy.
• Developing confidence in mathematics.

Why Addition Skills Are Important

Addition serves as the foundation for nearly every future math concept. Before students can master subtraction, multiplication, division, fractions, or algebra, they must first understand how numbers combine.

Strong addition skills help students:

• Solve everyday math problems.
• Develop logical thinking abilities.
• Build confidence in mathematics.
• Improve mental calculation skills.
• Prepare for advanced arithmetic concepts.

Understanding Addition Without Regrouping

Addition without regrouping occurs when the sum of the ones digits is less than ten. Students can solve these problems by simply adding the digits in the ones place while keeping the tens digit unchanged.

For example:

• 17 + 5 = 22
• 10 + 1 = 11
• 15 + 5 = 20
• 12 + 6 = 18

These types of problems help students build confidence before progressing to more complex addition involving regrouping.

Learning Objectives

After completing this worksheet, students should be able to:

• Add a one-digit number to a two-digit number accurately.
• Solve addition problems without regrouping.
• Apply place value knowledge during calculations.
• Improve arithmetic fluency.
• Develop stronger number sense.
• Increase confidence in solving math problems independently.
