Repeated Addition Activity | Solved Exercises

Solution: Exercises 1 to 3

1 Dice activity

Exercise 1

Roll a die 3 times and add the results. If you roll 4, 4, 4 - what's the sum using repeated addition?

Definition:

Repeated Addition Activity: Using games and physical objects to practice adding the same number multiple times.

Activity Method:

Roll the die multiple times
Record each result
Identify if numbers repeat
Set up repeated addition expression
Calculate the total

Rolls

4, 4, 4

Repeated Addition

4 + 4 + 4

Result

🎲

Step 1: Record the rolls

You rolled: 4, 4, 4 (all the same number!)

Step 2: Set up the repeated addition

Since all rolls are 4, we write: 4 + 4 + 4

Step 3: Calculate step by step

First: 4 + 4 = 8, then: 8 + 4 = 12

Step 4: Connect to multiplication

This is the same as 3 × 4 = 12

4 + 4 + 4 = 12

Final answer:

The sum of the dice rolls is 12

Applied rules:

• Repeated addition: Adding the same number multiple times

• Game-based learning: Making math fun through play

• Multiplication foundation: 3 × 4 = 12

Activity Tip: Games make math practice enjoyable and memorable!

Learning Tip: Physical activities help solidify math concepts.

Step 3: Set up repeated addition

3 apples for basket 1 + 3 for basket 2 + 3 for basket 3 + 3 for basket 4

Step 4: Calculate the total

3 + 3 + 3 + 3 = 12 apples

You need 12 apples in total

Final answer:

You need 12 apples in total

Applied rules:

Situation

5 cats × 4 legs each

Repeated Addition

4 + 4 + 4 + 4 + 4

Result

Step 1: Count the animals

You see 5 cats

Step 2: Identify legs per animal

Each cat has 4 legs

Step 3: Set up repeated addition

4 legs from cat 1 + 4 from cat 2 + 4 from cat 3 + 4 from cat 4 + 4 from cat 5

Step 4: Calculate the total

4 + 4 + 4 + 4 + 4 = 20 legs

You see 20 legs altogether

Final answer:

You see 20 legs altogether

Applied rules:

• Attribute counting: Counting specific features of objects

4 Reading books activity

Exercise 4

You read 3 books each day for 4 days. How many books did you read in total?

Definition:

Time-Based Activity: Activities that span multiple time periods with consistent quantities.

📅

Day 1:

📖

📅

Day 2:

📖

📅

Day 3:

📖

📅

Day 4:

📖

Situation

4 days × 3 books each

Repeated Addition

3 + 3 + 3 + 3

Result

Step 1: Identify the time period

You read for 4 days

Step 2: Identify books per day

Each day you read 3 books

Step 3: Set up repeated addition

3 books on day 1 + 3 on day 2 + 3 on day 3 + 3 on day 4
