Skill: Subtract within 5

Explanation and Free Practice Resources

Subtraction within 5 represents taking away, finding the difference between two quantities, or determining an unknown part in situations involving 0–5 objects; learners connect equations such as 5−2=35-2=3 with quantities, dot sets, and movement backward on a number line. They understand that subtraction is related to addition, includes subtracting zero and subtracting a quantity from itself, and is not commutative; regrouping, multi-digit computation, and subtraction with larger numbers are beyond this scope.

Detailed Explanation: Subtract within 5

Subtraction means taking away to find how many are left.

Example: Solve 5−25-2.

  1. Start with 55 objects:
    ● ● ● ● ●

  2. Take away 22 objects:
    ● ● ● ● ●

  3. Count the objects left. There are 33.

So,

5−2=35-2=3

You can also start at 55 on a number line and move backward 22 steps:

5→4→35 \rightarrow 4 \rightarrow 3

The answer is 33.
