Max Rescues Dragonflies: Subtraction Speed Challenge!

About this Grade 1 Subtraction Drill

Subtraction is one of the first ways young mathematicians learn to think about how quantities change. At six and seven years old, children are naturally curious about "taking away"—when they share snacks, lose a toy, or count down to playtime. Mastering subtraction within 10 helps your child build number sense, understand part-whole relationships, and develop the mental flexibility needed for all future math. These early subtraction skills also strengthen working memory and logical thinking, which support reading comprehension and problem-solving across all subjects. When a child can confidently say "9 minus 3 equals 6," they're not just memorizing facts—they're learning how the world works mathematically.

What your student will practice

• Subtract single-digit numbers from 10 or less with accuracy
• Represent subtraction using objects, pictures, or number lines
• Recognize the minus symbol and identify the minuend, subtrahend, and difference
• Apply subtraction to simple real-world word problems

Common mistakes to watch for

The most common error at this age is confusing the order of numbers in subtraction. A child might write 3 − 7 when they mean 7 − 3, or they'll subtract the larger number from the smaller one because they haven't internalized that we start with the "whole" amount. Watch for students who count on their fingers but lose track of how many they've counted, or who write an answer that's larger than the starting number—a sign they're guessing rather than thinking. You'll also notice some children reverse their thinking and add instead of subtract when they see a problem, especially if addition was recently practiced.
