Subtraction problems for 1st grade: 1st Grade Subtraction Worksheets — free & printable

Subtraction | 1st Grade Math

Imagine you have 3 apples, and you give 2 apples to your friends. 

How many apples do you have left?

To find the answer, you use subtraction!

3 — 2 = ?

What Is Subtraction?

Subtraction is when you take one number away from another.

Subtraction uses a minus (-) symbol.

3 — 2 = 1

Subtraction is the opposite of addition.

If you know 2 + 1 = 3, you also know that 3 — 2 = 1.

Subtraction Using Your Fingers

You can solve easy subtraction problems on your fingers.

Let’s learn how by solving 5 — 3 = ?

Look at the first number, 5. Start by raising that many fingers.

Then take away 3 fingers.

How many fingers are left? 2

So 5 — 3 = 2! 🎉 Congratulations, you just did subtraction.

Subtraction Using Diagrams

7 — 3 = ?

Subtraction using fingers is pretty slow.

Let’s try to solve this subtraction using a drawing.  

Look at the first number, 7. Start by drawing that many circles on a piece of paper:

Then cross out 3 of them:

How many circles are left? 4

So using diagrams, we figured out that:

7 — 3 = 4 ✅

Subtraction Terms

Each part of a subtraction equation has a name, or term.

The first number is called the minuend.

The subtrahend is the number after a minus symbol.

The answer to a subtraction problem is called the difference.  

Tip for remembering:

Knowing these terms makes it easier for us to learn more about subtraction. 

Subtraction Is the Opposite of Addition

A great way to think about subtraction is it’s the opposite of addition.

When you see:

5 — 2 = ?

… just think, «What number plus 2 equals 5?»

Yes! 3 + 2 equals 5! So, 5 — 2 = 3. 

Tip: 2 and 3 are parts of the same whole, 5.

Subtraction Basics

Subtracting by 1

When you subtract by 1, it’s like counting down by 1.

7 — 1 = 6
6 — 1 = 5
5 — 1 = 4

Subtracting Doubles

When you subtract a number from itself, the answer is always zero. Take a look:

7 — 7 = 0

4 — 4 = 0

Order Matters

When subtracting, the order of the numbers matters.

For example, 3 — 2 is not the same as 2 — 3.

Great job learning about subtraction. 

Now, complete the practice.

Grade 1 — Elementary Math

Overview

Think Math! is based on the principle that children are curious about problem solving. The content of each level of learning builds a penchant for puzzle solving, develops math “mind habits” through games, puzzles, mental math, and other collaborative activities to provide a fun and motivating experience for a diverse student community. nine0003

B Think about math! , first graders are eager to explore mathematical relationships. They sort and classify by attributes and explain sorting rules. They think of addition and subtraction as jumps on the number line, understanding that the plus jump moves forward and the minus jump moves backward. Training focuses on strategies for adding and subtracting within 20, including doubling, dividing numbers in half, and pairing numbers up to 10 and 20 — eventually progressing to higher numbers up to 120 by learning digits and grouping. They experiment with linear measurements, using both custom and standard units to measure various objects. nine0003

Standards of Math Practice for 1st Grade

Standards of Math Practice K-12 describes the different types of knowledge that math teachers at all levels should strive to develop in their students. This page provides examples of what the 1st grade standards of practice look like.
nine0003

Standards

Explanations and examples

1. Understand problems and persevere in solving them.

1st grade students who have mathematical ability learn problems (problems), can understand the meaning of the problem and find a starting point or a way to start the task. 1st grade students also build the foundation for problem-solving strategies and learn how to use those strategies independently to solve new problems. In grade 1, student work builds on kindergarten principles and still relies heavily on concrete manipulation and graphic representations. The exception is when CCSS uses the word fluent for mental math. Grade 1 students should also be persistent in solving problems; that is, if students reach a point where they are stuck, they can revisit the problem and continue with the problem. Finally, at the end of the task, the math-savvy students in the class ask themselves, “Does my answer make sense?” nine0003

2. Think abstractly and quantitatively.

1st grade students with mathematical ability understand quantities and relationships when solving problems. This involves two processes — decontextualization and contextualization. In Grade 1, students represent situations by decontextualizing tasks into numbers and symbols. For example, in the task “There are 60 children on the playground, and some children are lining up. If 20 kids are still playing, how many kids are lined up? Grade 1 students are expected to translate this situation into an equation: 60 — 20 = ___ and then solve the problem. Students also contextualize situations in the process of problem solving. For example, in the problem above, students refer to the context of the problem to determine that they need to subtract 20 because the number of children in the playground is the total, except for 20 who are still playing. Reasoning processes are also class 1 because they consider ways to divide two-dimensional geometric shapes into halves and quarters. nine0003

3. Come up with viable arguments and criticize the reasoning of others.

1st grade students with mathematical ability accurately use definitions and previously established answers to build sound arguments in mathematics. For example, when solving the problem “There are 15 books on the shelf. If you take a few books off the shelf and there are 7 books left, how many books will you take off the shelf?” Students will use different strategies to solve the problem. After solving the problem, 1st grade students are expected to share problem solving strategies and discuss the validity of their classmates’ strategies. nine0003

4. Model with mathematics.

Math-savvy 1st grade students model real-life math situations using a number sentence or equation and check that their equation matches exactly the context of the problem. Grade 1 students rely on specific manipulations and graphic representations to solve problems, but they are also expected to write an equation to model problem situations. For example, when solving the problem “there are 11 bananas on the counter”. If you eat 4 bananas, how many will be left? 1st grade students should write the equation 11-4 = 7. Similarly, 1st grade students should construct the appropriate problem situation from the equation. For example, students are expected to complete the story task for Equation 13-7 = 6.9.0007

5. Use the right tools strategically.

1st grade students who are good at math have access to and use tools properly. These tools may include counters, decimal blocks, hundreds boards, number lines, and specific geometric shapes (eg, pattern blocks, 3D solids). Students should also have experience with educational technologies such as calculators and virtual manipulators that support conceptual understanding and higher order thinking skills. During classroom learning, students should have access to a variety of math tools as well as paper and determine which tools are most appropriate to use. For example, by solving 12 + 8 = __, students explain why shock blocks are more appropriate than counters. nine0003

6. Pay attention to accuracy.

1st grade students with mathematical ability are accurate in communication, calculation and measurement. In all math problems, Grade 1 students clearly describe their actions and strategies, accurately using vocabulary appropriate to their grade, and giving precise explanations and reasoning about their decision-making process. For example, by measuring objects iteratively (repeatedly), students check for gaps or overlaps. When performing tasks for the sense of number, students check their work to make sure that the decisions are correct and reasonable. nine0003

7. Look for and use structure.

Math-savvy 1st grade students carefully look for patterns and patterns in the number system and other areas of mathematics. When solving addition problems, students begin to realize the commutative property that 7 + 4 = 11, and 4 + 7 = 11. When decomposing two-digit numbers, students understand that any two-digit number can be divided into tens, and for example. 35 = 30 + 5, 76 = 70+6. Also, 1st grade students use structure when they are working with subtraction since missing term problems like 13- 7 = __ can be written as 7+ __ = 13 and can be seen as how much more do I need to add to 7 to get to 13? nine0003

8. Look for and express patterns in repetitive reasoning.

Mathematically savvy Grade 1 students begin to look for patterns in problem structures when solving mathematical problems. For example, when adding three single digit numbers and using the «Do 10» or «Doubling» strategies, students perform future tasks looking for opportunities to apply the same strategies. For example, when solving 8+7+2, a student might say, «I know that 8 and 2 are 10, and then I add 7 to get 17. This helps to see if I can make 10 out of 2 numbers when I start «. Next, students use repeated reasoning when solving a problem with multiple correct answers. For example, in the task “There are 12 crayons in a box. Some are red and some are blue. How many can there be? 1st grade students should understand that among 12 crayons there can be 6 pencils of each color (6+6 = 12), 7 of one color and 5 of another (7+5 = 12). nine0003
