About this Grade 1 Subtraction Drill

Subtraction is how your child learns that numbers can get smaller, a skill they use constantly in daily life—whether sharing toys, finding change, or figuring out how many snacks are left. At ages 6-7, students are developing number sense and learning that subtraction is the opposite of addition, which strengthens their overall math foundation. This drill builds automaticity with smaller numbers (within 10-20), so your child can solve problems fluently without counting on their fingers every time. Practicing subtraction regularly also grows confidence and prepares them for word problems, where they'll need to recognize when subtraction is the right tool. Most importantly, these skills help children think logically about quantity and change—skills that transfer to reading, sports strategy, and everyday decision-making.

What your student will practice

• Subtract single-digit numbers from numbers 10-20 with accuracy
• Recognize subtraction as taking away or removing objects
• Build automaticity and recall of basic subtraction facts
• Apply subtraction to simple real-world situations and word problems

Common mistakes to watch for

The most common error is 'counting from the wrong number'—for example, when solving 9 - 3, students count "3, 4, 5" instead of starting at 9 and counting backward. Another frequent mistake is confusing the direction of subtraction; they might solve 5 - 2 as 2 - 5. Watch for students who count on their fingers for every problem, which suggests they haven't internalized the facts yet. If your child consistently gets the same problems wrong or skips problems without attempting them, they may need slower practice with concrete objects (blocks, counters) before moving to written problems.
