Dinosaur Subtraction Adventure: Stomp and Count

About this Grade 1 Subtraction Drill

Subtraction is one of the first mathematical operations that helps first graders make sense of the world around them. At age 6-7, children are naturally curious about "taking away"—whether it's eating cookies from a plate, removing toys from a pile, or counting how many dinosaurs are left after some walk away. Learning to subtract builds number sense and prepares students for addition and multi-digit math later. It also strengthens mental flexibility; children learn that numbers can be broken apart and recombined in meaningful ways. Subtraction practice develops counting-backward skills, which support reading, skip-counting, and problem-solving across subjects. Most importantly, it gives young learners confidence that they can work through small challenges using logic and their fingers if needed.

What your student will practice

• Subtract within 10 using fingers, objects, or number lines
• Recognize and write subtraction sentences (minuend − subtrahend = difference)
• Solve word problems that ask "how many are left"
• Build fluency with subtraction facts from 0 to 10

Common mistakes to watch for

The most common error at this age is counting incorrectly when removing objects. For example, a child might count "10, 9, 8" when subtracting 3 from 10, but lose track and land on 6 instead of 7. Watch for students who forget to start with the larger number or who recount the whole set instead of removing items first. Another frequent mistake is confusing the direction: they may add instead of subtract when they see the minus sign, especially if they're rushing. If a student seems stuck or frustrated, ask them to physically move objects apart—this concrete step prevents mental counting errors.
