Adding and Subtracting to 20 Worksheet – 1st Grade Addition Practice

Adding and Subtracting to 20 Worksheet helps first grade learners practice addition with clear directions and a clean, kid-friendly layout. Print it and it is ready for class, homework, or homeschool lessons.

Learning objective: Students will build accuracy and confidence with addition through short, focused practice that reinforces what was taught in class.

Why it works: Students stay on task because the directions are short and the practice is the right size for one sitting. Teachers save time because the page is ready to print and easy to check.

What's included:

• 1 printable worksheet page

• Clear, student-friendly directions

• Answer key (1 page)

• Cover page

How it's organized: The page opens with these directions: "Solve each equation. Write the sum or difference in the box." 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: It works well for whole-class lessons, small groups, early finishers, homework, review days, intervention time, and sub tubs.

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

Teaching tips and variations:

• Use it as an exit ticket the day after a addition lesson to see who needs more support.

• Project the page and solve one or two items as a class before students work on their own.

• Model the first item together, then let students finish the rest independently.
