About this Grade 1 Subtraction Drill

Subtraction is one of the first ways young learners understand "taking away" and comparing quantities—skills they use every day without realizing it. When your child counts down blocks while playing, figures out how many cookies are left after sharing, or notices a friend left the group, they're doing subtraction naturally. At age 6-7, students are building the mental images and number sense needed to solve problems fluently and eventually work with larger numbers. This worksheet helps solidify their ability to visualize subtraction using numbers up to 10 or 20, which is exactly where first graders need to be confident. Regular practice with subtraction facts also strengthens their understanding of how addition and subtraction are connected—a big idea in early math. Most importantly, mastering these basics now prevents frustration and builds the foundation for all future math success.

What your student will practice

• Solve single-digit subtraction problems with fluency and accuracy
• Understand subtraction as "taking away" or "finding the difference"
• Use strategies like counting on fingers or drawing to solve problems
• Recognize the subtraction symbol and correctly write subtraction sentences

Common mistakes to watch for

The most common error is students counting incorrectly when they "count back." For example, with 9 − 3, they say "9, 8, 7" but forget to count the 9 as their starting point and land on 5 instead of 6. Watch for children who can't keep track of how many they've counted back, or who lose focus mid-problem. Another frequent mistake is reversing the numbers—writing or solving 3 − 9 when they meant 9 − 3. If your child consistently gets answers that are too small or too large, ask them to recount aloud while pointing to their fingers or objects.
