5 + 5 = 10, then 10 + 5 = 15, then 15 + 5 = 20, then 20 + 5 = 25

Step 3: Identify the pattern

Each addition increases the total by 5

Step 4: Write the complete equation

5 + 5 + 5 + 5 + 5 = 25

5 + 5 + 5 + 5 + 5 = 25
Final answer:

5 + 5 + 5 + 5 + 5 = 25

Key concepts:

• Sequential pattern: Each result increases by the repeated number

• Consistent increment: Same number added repeatedly

• Pattern recognition: Identifying mathematical relationships

Pattern Tip: Look for how the total changes each time!
Counting Tip: Count by the repeated number to verify your answer.

6 + 6 + 6 = 18
Final answer:

You have 18 crayons in total.

Repeated addition equation: 6 + 6 + 6 = 18

Key concepts:

• Real-world application: Math connects to everyday situations

4 Comparison Example
Exercise 4
Compare: 2 + 2 + 2 + 2 + 2 vs 3 + 3 + 3 + 3. Which is greater?

●
●
= 12
First
2×5=10
Second
3×4=12
Compare
10 < 12
Step 1: Calculate first expression

2 + 2 + 2 + 2 + 2 = 10

Step 2: Calculate second expression

3 + 3 + 3 + 3 = 12

Step 3: Compare the results

10 vs 12, so 12 is greater

Step 4: Write the comparison

3 + 3 + 3 + 3 > 2 + 2 + 2 + 2 + 2

3 + 3 + 3 + 3 = 12 > 10 = 2 + 2 + 2 + 2 + 2
Final answer:

3 + 3 + 3 + 3 = 12 is greater than 2 + 2 + 2 + 2 + 2 = 10

Key concepts:

• Quantitative comparison: Compare sums to determine greater value

• Pattern analysis: Different groupings can produce different totals

• Relational thinking: Understanding greater than and less than relationships

Comparison Tip: Calculate both sides before comparing!
Analysis Tip: Different numbers of groups can affect the total.
