Looking for simple, effective addition practice for first grade? The Adding 3 Single Digit Number Worksheet is a ready-to-print math resource that students can complete on their own after a short introduction.

Learning objective: Students will review addition, practice it in context, and show what they know in a way that is easy for the teacher to check.

Why it works: Short, focused practice is one of the best ways to help first grade students remember a new skill. Clear directions mean students can get started quickly, and the simple format makes it easy for you to spot who needs more help.

How it's organized: The page opens with these directions: "Add the three numbers. Write the sum below the line. Each answer is within 20." Students then complete the practice items in order and check their work before turning it in.

Grade level: Designed for first grade students. It also works well for kindergarten and second grade students who need extra practice or a fresh review.

How to use it: Assign it after a mini-lesson, use it in a small group, send it home as homework, keep it in your sub folder, or use it as a quick formative check.

Answer key: An answer key is included, so you can check work quickly or let students self-correct.
