Learning Objective

Students will be able to subtract numbers within 20 using counting back, drawings, and number sentences to show their working.

Teacher Tip

After Q6, pause and ask students to act out Maya sorting seeds — one child holds up fingers for the starting number while classmates count back aloud as seeds are 'planted.' This physical countdown directly mirrors the take-away subtraction structure students calculated in Q6 (15 minus 8).

About this Math worksheet for Grade 1

In first grade, students develop foundational understanding of subtraction as 'taking away' through repeated practice with small numbers, which directly supports CCSS.MATH.1.OA.C.6's focus on relating subtraction to addition within 10. Teachers can use this resource to provide scaffolded practice where students solve problems by crossing out or counting backward, building the mental math strategies necessary before moving to two-digit computation in grade 2.

This printable Math worksheet is designed for Grade 1 students and covers Subtraction. The Eco Warriors theme keeps kids engaged while they practice essential Math skills. Every worksheet includes a full answer key making it easy for parents and teachers to check work instantly. Aligned to Common Core State Standards (CCSS) for Grade 1 Math.

Why Subtraction matters in Grade 1

Subtraction is one of the first big math skills your child will master, and it's essential for everyday decision-making. At ages 6-7, children are developing the ability to understand "taking away" and how quantities change—skills they'll use when sharing snacks, managing toys, or thinking about what's left after playtime. By learning subtraction now, your child builds the foundation for all future math, including word problems and multi-step thinking. More importantly, subtraction helps develop number sense and mental flexibility. When children practice subtraction regularly, they're also strengthening their ability to count backward, recognize number patterns, and solve problems independently. These early experiences with subtraction create confident, curious math learners who see numbers as tools for understanding the world around them.

What your student will practice

Common mistakes to watch for

The most common mistake Grade 1 students make is counting down incorrectly from the starting number. For example, when solving 7 - 2, many children count "7, 6, 5" and land on 5 as their answer, forgetting to count 2 steps. Watch for students who use their fingers but lose track of how many they've counted. Another frequent error is reversing the numbers—subtracting the larger from the smaller—because they haven't yet firmly grasped that the first number must be larger. If your child seems confused about which number to start with, use physical objects to make the process concrete and visible.

Teacher & Parent Tip

Create a subtraction activity during snack time or toy cleanup. Give your child a small group of items (crackers, blocks, or stuffed animals—8 or fewer), remove some while they watch, and ask, "How many are left?" Start with removing just 1 or 2 items so success builds confidence. This hands-on approach helps your child see subtraction as a real action, not just abstract symbols on paper. Eco-warriors know that every choice counts—just like every number counts in math!
