Adding and Subtracting to 20 Worksheet

Building fluency with addition and subtraction within 20 is one of the most important early math milestones, and this adding and subtracting to 20 worksheet gives young learners the focused practice they need. At this stage, children move beyond counting on their fingers and begin to recall math facts quickly, using strategies like making ten, counting on, and using doubles. Solving a balanced mix of addition and subtraction problems side by side helps students see how the two operations connect and strengthens the number sense they will rely on for years to come.

This first grade addition and subtraction worksheet presents ten clear equations in a bright, easy-to-read layout, each paired with an answer box where students write the sum or difference. To use it, simply print the page and have your child solve each equation from left to right, encouraging them to say the strategy they used out loud. A cheerful farm-stand illustration of red and green apples ties the practice to a real counting situation, making abstract math feel friendly and concrete.

What’s Included

• 1 print-ready PDF worksheet
• Answer key
• 10 addition and subtraction equations within 20

There are three big reasons this adding and subtracting to 20 worksheet helps children learn. First, mixing addition and subtraction on the same page trains flexible thinking, so students learn to read each problem carefully instead of repeating one operation on autopilot. Second, the roomy answer boxes and generous spacing keep the page uncluttered, which lowers frustration and helps early writers form their numbers neatly. Third, the included answer key lets kids check their own work and lets teachers grade in seconds, turning practice into an immediate feedback loop that builds confidence.

To extend the learning, turn the equations into a hands-on game: grab twenty counters, buttons, or dried beans and have your child build each problem before writing the answer. You can also challenge students to write their own addition and subtraction stories about the apple baskets, or race to beat a one-minute timer for a fun fluency drill. Reviewing just a few problems each day at home or during math centers keeps skills sharp without feeling like a chore.
