Solved Exercises on Counting Money in Grade 2

Master counting money: coin recognition, addition, comparison, and practical applications through these 5 detailed exercises.

Solution: Exercises 1 to 3
1 Coin Recognition
Exercise 1
Look at these coins: penny, nickel, dime, quarter. What is the value of each coin?
Definition:

Coins and their values: Penny = 1¢, Nickel = 5¢, Dime = 10¢, Quarter = 25¢

Recognition method:
  1. Memorize the value of each coin
  2. Practice with physical coins or pictures
  3. Compare sizes and colors to identify coins
1¢
5¢
10¢
25¢
Step 1: Learn coin values

Penny = 1 cent (smallest coin, copper color)

Step 2: Learn coin values

Nickel = 5 cents (silver color, larger than penny)

Step 3: Learn coin values

Dime = 10 cents (silver color, smaller than nickel)

Step 4: Learn coin values

Quarter = 25 cents (largest silver coin)

Penny = 1¢, Nickel = 5¢, Dime = 10¢, Quarter = 25¢
Final answer:

Penny = 1¢, Nickel = 5¢, Dime = 10¢, Quarter = 25¢

Applied rules:

• Memorization: Remember each coin's value

• Recognition: Identify coins by size and color

• Practice: Handle coins regularly to build familiarity

2 Adding Coins
Exercise 2
Sarah has 3 pennies, 2 nickels, and 1 dime. How much money does she have?
Definition:

Addition of coins: Count the total value by adding each coin's value

1¢
1¢
1¢
5¢
5¢
10¢
Total: 23¢
Step 1: Count pennies

3 pennies × 1¢ = 3¢

Step 2: Count nickels

2 nickels × 5¢ = 10¢

Step 3: Count dimes

1 dime × 10¢ = 10¢

Step 4: Add all amounts

3¢ + 10¢ + 10¢ = 23¢

Sarah has 23¢
Final answer:

Sarah has 23¢

Applied rules:

• Multiplication: Number of coins × value of each coin

• Addition: Add all individual totals together

• Organization: Group same coins together before adding

3 Comparing Amounts
Exercise 3
Tom has 2 quarters and 3 dimes. Jane has 1 quarter and 6 dimes. Who has more money?
Definition:

Comparing amounts: Calculate each person's total and compare

25¢
25¢

Tom: 80¢
25¢
10¢
10¢
10¢
10¢
10¢
Jane: 85¢
Step 1: Calculate Tom's total

2 quarters = 2 × 25¢ = 50¢

3 dimes = 3 × 10¢ = 30¢

Total = 50¢ + 30¢ = 80¢

Step 2: Calculate Jane's total

1 quarter = 1 × 25¢ = 25¢

6 dimes = 6 × 10¢ = 60¢

Total = 25¢ + 60¢ = 85¢

Step 3: Compare the totals

85¢ > 80¢, so Jane has more money

Jane has more money (85¢ vs 80¢)
Final answer:

Jane has more money (85¢ vs 80¢)

Applied rules:

• Calculate each amount separately

• Compare totals using greater than (>) or less than (<)

• Verify calculations to avoid mistakes

Penny = 1¢, Nickel = 5¢, Dime = 10¢, Quarter = 25¢
Coin Values
Addition Rule
Total = Sum of all coins
Count each coin and add values
Multiplication Rule
Value = Number × Individual Value
Count coins and multiply by value
Comparison Rule
Compare totals
Calculate both amounts and compare
Key definitions:

Cent (¢): Unit of currency equal to 1/100 of a dollar

Coin: Small metal piece used as money

Value: Worth of a coin in cents

Complete methodology:
  1. Identify coins: Recognize each coin and its value
  2. Count coins: Determine how many of each type
  3. Calculate value: Multiply number by individual value
  4. Add totals: Sum all coin values
  5. Compare if needed: Check which amount is greater
Tip 1: Start with largest coins (quarters) and work down to smallest (pennies).
Tip 2: Group same coins together before adding.
Tip 3: Use skip counting: count by 5s for nickels, 10s for dimes, 25s for quarters.
Tip 4: Practice with real coins to build tactile recognition.
Common errors: Confusing coin values, miscounting, forgetting to add all coins.
Practice strategies: Use physical coins, draw coin pictures, play money games.
Solution: Exercises 4 to 5
4 Making Change
Exercise 4
A candy costs 37¢. You give 50¢. How much change should you get back?
Definition:

Change calculation: Change = Amount given - Cost

Step 1: Identify the cost

Candy costs 37¢

Step 2: Identify amount given

You gave 50¢

Step 3: Calculate change

Change = 50¢ - 37¢ = 13¢

Step 4: Show change in coins

13¢ = 1 dime + 1 nickel + 3 pennies

Change = 13¢ (1 dime, 1 nickel, 3 pennies)
Final answer:

You should get 13¢ back (1 dime, 1 nickel, 3 pennies)

Applied rules:

• Subtraction: Amount given minus cost equals change

• Breaking down: Express change in coins

• Verification: Check that cost + change = amount given

5 Money Word Problem
Exercise 5
Maya saved 4 quarters, 6 dimes, 8 nickels, and 12 pennies. She wants to buy a toy that costs $1.25. Does she have enough money?

Step 1: Calculate quarters value

4 quarters × 25¢ = 100¢ = $1.00

Step 2: Calculate dimes value

6 dimes × 10¢ = 60¢

Step 3: Calculate nickels value

8 nickels × 5¢ = 40¢

Step 4: Calculate pennies value

12 pennies × 1¢ = 12¢

Step 5: Calculate total savings

$1.00 + 60¢ + 40¢ + 12¢ = $1.00 + $1.12 = $2.12

Step 6: Compare to toy cost

$2.12 > $1.25, so Maya has enough money

Maya has $2.12, which is more than $1.25
Final answer:

Yes, Maya has $2.12 which is more than $1.25 needed for the toy

Applied rules:

• Organize by coin type: Calculate each group separately

• Convert to dollars: 100¢ = $1.00

• Compare amounts: Check if savings ≥ cost

Money Counting Fundamentals & Strategies
Total = Σ(Coin Value × Quantity)
Money Addition Formula
Key definitions:

Dollar ($): Currency unit where 100 cents = 1 dollar

Counting money: Adding the value of multiple coins

Word problems: Real-life scenarios requiring money calculations

Complete methodology:
  1. Identify all coins: Recognize each type and its value
  2. Group same coins: Organize by type (quarters, dimes, etc.)
  3. Calculate each group: Multiply quantity by value
  4. Sum all groups: Add all calculated values
  5. Convert if needed: Change cents to dollars when necessary
  6. Compare or apply: Use total for comparisons or purchases
Tip 1: Use skip counting: count quarters by 25s (25, 50, 75, 100...).
Tip 2: Dimes are easy - just count by 10s (10, 20, 30...).
Tip 3: Nickels count by 5s (5, 10, 15, 20...).
Tip 4: Always verify your answer by adding in reverse order.
Memory aids: "Penny for your thoughts" (1¢), "Nickel and dime" (5¢, 10¢), "Quarter of a dollar" (25¢).
Real-world connection: Practice with actual store prices and shopping scenarios.
Essential Rules:

• Penny = 1¢, Nickel = 5¢, Dime = 10¢, Quarter = 25¢

• 100 cents = 1 dollar

• Always organize coins before counting

• Start with highest value coins for efficiency

• Check your work by recounting or using a different method

Questions & Answers

Question: I always get confused about the difference between dimes and pennies. They're both small and round. How can I tell them apart?

Answer: Great question! Here are key differences between dimes and pennies:

  • Size: Dimes are smaller than pennies (counterintuitive but true!)
  • Color: Dimes are silver/grey, pennies are copper/brown
  • Thickness: Dimes are thinner than pennies
  • Value: Dimes = 10¢, Pennies = 1¢

Memory trick: "Dime" has 4 letters, and it's worth 10¢ (think of 4 fingers when counting to 10). Pennies are worth just 1¢, like the first letter of "penny".

Practice handling real coins - the tactile difference helps with recognition!

Question: When counting money, should I add the big coins first or the small coins first? It's confusing!

Answer: It's usually easier to start with the biggest coins (quarters = 25¢) and work down to the smallest (pennies = 1¢). Here's why:

  • Starting with bigger amounts gets you closer to the total faster
  • It's easier to keep track of the running total
  • You can use skip counting: count by 25s for quarters, then 10s for dimes, then 5s for nickels, then 1s for pennies

Example: 2 quarters, 1 dime, 1 nickel, 3 pennies
Start: 25¢, 50¢ (quarters)
Then: 60¢ (add dime)
Then: 65¢ (add nickel)
Finally: 66¢, 67¢, 68¢ (add pennies)

This method reduces the chance of losing track!

Question: My child is struggling with word problems about money. How can I help them understand what to do?

Answer: Word problems can be challenging! Try this step-by-step approach:

  1. Read together: Have your child read the problem aloud slowly
  2. Find the question: What are they being asked to find?
  3. Circle important words: Numbers, coin names, "total", "more than", "change", etc.
  4. Draw it out: Sketch the coins mentioned in the problem
  5. Solve step by step: Count or calculate as needed
  6. Check: Does the answer make sense?

Example: "Sarah has 3 dimes and 2 nickels. Does she have enough for a 40¢ pencil?"
→ Draw 3 dimes (30¢) + 2 nickels (10¢) = 40¢
→ Yes, she has exactly enough!

Practice with real-life scenarios like shopping or saving for toys!
