Solution: Exercises 1 to 3
1 Basic repeated addition
Exercise 1
Add the same number four times:
\( 3 + 3 + 3 + 3 \)
Definition:

Repeated addition: Adding the same number multiple times is the same as multiplying the number by the count of additions.

Method:
  1. Count how many times the number appears
  2. Multiply the number by the count
  3. Verify by adding step by step

Step 1: Count the additions

We have 4 copies of the number 3

Step 2: Apply multiplication shortcut

\( 4 \times 3 = 12 \)

Step 3: Verify by adding

\( 3 + 3 + 3 + 3 = 6 + 6 = 12 \)

Key Point: Adding the same number is multiplication in disguise!
\( 3 + 3 + 3 + 3 = 12 \)
Final answer:

\( 3 + 3 + 3 + 3 = 12 \)

Applied rules:

• Repeated addition: n additions of same number = n × number

• Counting principle: How many groups × size of each group

• Multiplication connection: Addition and multiplication are related

2 Repeated addition with larger numbers

Applied rules:

• Equal grouping: All groups must have the same number of items

• Multiplication pattern: n groups of m = n × m

• Total calculation: Number of groups × items per group

56
Key Point: 7 boxes with 8 cars each = 56 cars total!
\( 8 + 8 + 8 + 8 + 8 + 8 + 8 = 56 \) toy cars
Final answer:

There are 56 toy cars in total.

Questions & Answers

Question: Why does adding the same number multiple times equal multiplication? Like why does 5 + 5 + 5 equal 3 × 5?

Answer: This is because multiplication is just a faster way to write repeated addition!

  • Adding 5 + 5 + 5 = 3 groups of 5 = 3 × 5 = 15
  • Adding 6 + 6 + 6 + 6 = 4 groups of 6 = 4 × 6 = 24

Think of it like this: instead of writing "add 5, then add 5, then add 5", we write "3 groups of 5" which is 3 × 5.

Both operations mean the same thing: "take this number and use it this many times". Multiplication is just the shortcut way to write it!

Question: My child gets confused when counting the groups. How can I help them understand how many groups there are in problems like 7 + 7 + 7 + 7?

Answer: Visual representation works best for understanding groups:

  • Draw 4 separate circles, each containing 7 dots
  • Count the circles: there are 4 circles (groups)
  • Count the dots in each circle: there are 7 dots in each
  • So we have 4 groups of 7, which is 4 × 7 = 28

You can also use physical objects like blocks or counters to create actual groups that children can touch and count.

Relate it to real life: "If I have 4 bags with 7 apples in each bag, I have 4 groups of 7 apples."

Question: Is it better to add step by step or just multiply? Like should I do 6 + 6 + 6 + 6 = 12 + 12 = 24 or just 4 × 6 = 24?

Answer: Both methods are important at different stages of learning:

  • Initially: Add step by step to understand the concept (6 + 6 + 6 + 6 = 12 + 12 = 24)
  • Later: Use multiplication for speed and efficiency (4 × 6 = 24)
  • Always: Verify multiplication by adding to check your work

Start with adding to build understanding, then gradually move to multiplication as you become more comfortable. The goal is to understand WHY multiplication works, not just memorize it.

Think of multiplication as the "fast way" once you understand the "slow way"!
