3+3

Here's a detailed, step-by-step explanation in English for a 5th-grade level to understand the addition problem 3 + 3.

1. Understand the problem

• 3 + 3 means we are putting together two groups: one group of 3 and another group of 3.

2. Using a number line (visual method)

• Start at 0 on the number line.
• Move 3 steps to the right to reach 3.
• From there, move 3 more steps to the right.
• You land on 6.
• So, 3 + 3 = 6.

3. Using place value and quick reasoning

• The numbers 3 and 3 are both in the ones place (units).
• Adding them: 3 + 3 = 6.
• You can also think of it as doubles: 3 + 3 is the same as 2 × 3, which equals 6.

4. Quick mental math checks

• Double a number: 3 doubled is 6, so 3 + 3 = 6.
• Addition is commutative: 3 + 3 = 3 + 3, which also equals 6.

5. Answer

• 3 + 3 = 6

Extra practice (optional)

• 4 + 2 = 6
• 5 + 1 = 6
• 6 + 0 = 6
