Complete answer key with detailed solutions for counting coins: pennies, nickels, and dimes.

Solved Exercises 1 to 3
1 Counting Pennies and Nickels
Exercise 1
Count the total value of these coins:
4 pennies and 2 nickels
Coin Values:
penny
Penny
1¢
nickel
Nickel
5¢
Counting Method:
  1. Count the number of each type of coin
  2. Multiply the number of each coin by its value
  3. Add all amounts together
4
Pennies
4 × 1¢ = 4¢
2
Nickels
2 × 5¢ = 10¢
Step 1: Calculate each coin group

Pennies: 4 × 1¢ = 4¢

Nickels: 2 × 5¢ = 10¢

Step 2: Add all amounts

4¢ + 10¢ = 14¢

Total Value:
14¢
Final Answer:

The total value is 14¢

Applied Rules:

• Value Recognition: Know each coin's value

• Multiplication: Multiply count by value

• Addition: Sum all individual amounts

2 Counting Dimes and Pennies
Exercise 2
Sarah has 3 dimes and 7 pennies.
How much money does she have?
Problem Structure:

Total = (Number of Dimes × 10¢) + (Number of Pennies × 1¢)

3
Dimes
3 × 10¢ = 30¢
7
Pennies
7 × 1¢ = 7¢
Step 1: Calculate dimes value

3 dimes = 3 × 10¢ = 30¢

Step 2: Calculate pennies value

7 pennies = 7 × 1¢ = 7¢

Step 3: Add totals together

30¢ + 7¢ = 37¢

Total Value:
37¢
Final Answer:

Sarah has 37¢

Applied Rules:

• Value Recognition: Dime = 10¢, Penny = 1¢

• Multiplication: Count × Value

• Addition: Combine different coin values

3 Equivalent Values
Exercise 3
Show two different ways to make 15¢ using only pennies and nickels.
Equivalent Value Concept:

Same total value can be made with different combinations of coins

Step 1: Find possible combinations

Solution 1: 3 nickels = 3 × 5¢ = 15¢

Solution 2: 10 pennies + 1 nickel = 10¢ + 5¢ = 15¢

Step 2: Verify solutions

3 nickels: 3 × 5¢ = 15¢ ✓

10 pennies + 1 nickel: 10¢ + 5¢ = 15¢ ✓

Solution 1
3 nickels
15¢
Solution 2
10 pennies + 1 nickel
15¢
Final Answer:

Way 1: 3 nickels = 15¢

Way 2: 10 pennies + 1 nickel = 15¢

Applied Rules:

• Equivalent Values: Different coins can equal same amount

• Verification: Always check calculations

• Flexibility: Multiple solutions may exist

Detailed Summary and Key Concepts
Comprehensive Learning Guide
Definitions of Key Concepts

Coin: A small round piece of metal used as money

Cent (¢): The smallest unit of US money (100 cents = 1 dollar)

Penny: The smallest coin, worth 1 cent (brown/copper colored)

Five-Cent Piece: Worth 5 cents (silver colored)

Ten-Cent Piece: Worth 10 cents (silver colored)

Value: How much money a coin represents

Equivalent: Different combinations of coins that equal the same amount

Core Rules and Principles

• Rule 1: 1 penny = 1¢

• Rule 2: 1 five-cent piece = 5¢

• Rule 3: 1 ten-cent piece = 10¢

• Rule 4: To count coins, multiply number by value, then add

• Rule 5: 5 pennies = 1 five-cent piece

• Rule 6: 10 pennies = 1 ten-cent piece

• Rule 7: 2 five-cent pieces = 1 ten-cent piece

Step-by-Step Methods
  1. Step 1: Look at each coin and identify its type
  2. Step 2: Count how many of each type you have
  3. Step 3: Multiply the number by the value of that coin
  4. Step 4: Add all the amounts together
  5. Step 5: Write the answer with the cent symbol (¢)
Examples - From Simple to Advanced

Simple Example: 3 pennies = 3 × 1¢ = 3¢

Medium Example: 2 five-cent pieces = 2 × 5¢ = 10¢

Advanced Example: 1 ten-cent piece + 2 five-cent pieces + 4 pennies = 10¢ + 10¢ + 4¢ = 24¢

Tips and Tricks

• Tip 1: Start with the biggest coins first (ten-cent pieces, then five-cent pieces, then pennies)

• Tip 2: Count by 5s for five-cent pieces (5, 10, 15, 20...)

• Tip 3: Count by 10s for ten-cent pieces (10, 20, 30...)

• Tip 4: Use your fingers to keep track

• Tip 5: Always check your answer by counting again

Common Pitfalls to Avoid

• Mistake 1: Confusing the value of different coins

• Mistake 2: Forgetting to multiply number by value

• Mistake 3: Adding incorrectly

• Mistake 4: Forgetting the cent symbol (¢)

Key Notes for Memorization

• Memory Aid: "Penny = 1¢, Five-cent = 5¢, Ten-cent = 10¢"

• Pattern: Each coin is worth more than the last (1¢, 5¢, 10¢)

• Shortcut: 5 pennies equal 1 five-cent piece

• Shortcut: 10 pennies equal 1 ten-cent piece

Practice Problems and Applications
4 Shopping Scenario
Practice Problem 1
Tom has 6 pennies and 1 five-cent piece.
He wants to buy a candy that costs 11¢.
Does he have enough money?
Step 1: Calculate Tom's money

6 pennies = 6 × 1¢ = 6¢

1 five-cent piece = 1 × 5¢ = 5¢

Total = 6¢ + 5¢ = 11¢

Step 2: Compare to candy cost

11¢ = 11¢

Answer:

Yes, Tom has exactly enough money to buy the candy.

5 Savings Challenge
Practice Problem 2
Maria saves 2 ten-cent pieces every day for 3 days.
How much money does she have saved?
Step 1: Calculate daily savings

2 ten-cent pieces = 2 × 10¢ = 20¢ per day

Step 2: Calculate total savings

20¢ × 3 days = 60¢

Answer:

Maria has 60¢ saved after 3 days.

Questions & Answers

Question: I sometimes forget how much each coin is worth. How can I remember?

Answer: Here are helpful memory aids:

  • Penny: "P" for Penny = 1¢ (the smallest amount)
  • Five-cent: Has "five" in the name = 5¢
  • Ten-cent: Has "ten" in the name = 10¢
  • Size Memory: Biggest coin (ten-cent) = biggest value (10¢)

Practice by handling real coins and saying their values out loud. The more you practice, the easier it becomes!

Remember: The physical size doesn't always match the value!

Question: My child gets confused when counting mixed coins. What strategies can help them organize better?

Answer: Here are organization strategies:

  • Sort First: Put same coins together in separate piles
  • Count Aloud: Say the value as you touch each coin
  • Use Paper: Draw circles and write values next to each coin
  • Start Big: Count ten-cent pieces first, then five-cent pieces, then pennies

For example, with 2 ten-cent pieces, 1 five-cent piece, 3 pennies:

10, 20 (ten-cent pieces) → 25 (five-cent piece) → 26, 27, 28 (pennies)

This method helps prevent missing coins or double-counting!

Question: When do I use the cent symbol (¢) and when do I use the dollar symbol ($)?

Answer: For Grade 1, focus on the cent symbol (¢) for amounts less than $1.00:

  • Use ¢ symbol: For all amounts we're learning now (up to 100¢)
  • Rule: 100¢ = $1.00

Examples: 25¢, 50¢, 75¢, 99¢

You'll learn about dollars ($) in later grades when working with larger amounts.

Always write the cent symbol after the number: 25¢ not ¢25!
