Subtracting multiples of 10 is a foundational skill that helps first graders recognize patterns in our number system and build confidence with two-digit math. When children master subtracting 10, 20, 30, and beyond, they're learning that the ones place stays the same while only the tens place changes—a concept that makes later subtraction and mental math much easier. This skill directly supports the real-world math your child encounters daily, from counting coins to managing classroom supplies. At ages 6-7, children's brains are naturally drawn to patterns, making this the perfect time to cement this skill. Fluency with multiples of 10 also reduces the cognitive load when solving more complex problems, freeing up mental energy for other mathematical thinking. Strong mastery here means your child will tackle two-digit subtraction with ease and develop the number sense that keeps math feeling manageable, not overwhelming.
The most common error Grade 1 students make is subtracting from the ones place instead of the tens place—for example, solving 37 − 10 by changing the 7 to a 6, resulting in 36 instead of 27. You'll also see children forget that the ones digit never changes, sometimes inventing random answers. Watch for hesitation or finger-counting on every problem; this signals the student hasn't yet internalized the pattern. If your child is struggling, ask them to say the tens place out loud before solving: 'I have 3 tens, now I subtract 1 ten, so I have 2 tens left.'
Play a quick game at home using a deck of cards or even toy coins: show your child a two-digit number (like 45), then remove a group of 10 objects (pennies, blocks, or cards). Have them tell you what's left without counting each item individually. Repeat this daily for 3-5 minutes, and your child will begin to see the pattern automatically rather than relying on counting strategies. This hands-on, concrete experience helps the brain lock in the tens place rule faster than worksheets alone.
