Calgary Solutions: Exercises 1 to 3
1 Basic Change
Exercise 1
Sarah buys a hot dog at the Calgary Stampede for $3.50. She gives the vendor $5.00. How much change does she get?
Definition:

Making change: Returning the correct amount of money after a purchase at Calgary events

Method:
  1. Identify the cost of the item ($3.50)
  2. Identify the payment given ($5.00)
  3. Subtract cost from payment to find change
  4. Express the change in coins if needed
Step 1: Identify the values

Cost = $3.50, Payment = $5.00

Step 2: Subtract to find change

$5.00 - $3.50 = $1.50

Step 3: Express as coins

$1.50 = 1 loonie + 2 quarters OR 6 quarters

Change = $1.50 (1 loonie + 2 quarters)
Final answer:

Sarah gets $1.50 in change, which is 1 loonie and 2 quarters.

Applied rules:

• Subtraction: Payment - Cost = Change

• Coin value: 1 loonie = $1.00, 2 quarters = $0.50

• Verification: $3.50 + $1.50 = $5.00 ✓

2 Calgary Market
Exercise 2
Tom buys a maple syrup at the Calgary Farmers Market for $4.75. He pays with a $5.00 bill. How much change does he receive?
Definition:

Market transaction: Using Canadian currency at Calgary local markets

Step 1: Identify the values

Cost = $4.75, Payment = $5.00

Step 2: Subtract cost from payment

$5.00 - $4.75 = $0.25

Step 3: Express as coins

$0.25 = 1 quarter

Change = $0.25 (one quarter)
Final answer:

Tom receives $0.25 in change, which is one quarter.

Applied rules:

• Subtraction: $5.00 - $4.75 = $0.25

• Coin identification: $0.25 = 1 quarter

• Verification: $4.75 + $0.25 = $5.00 ✓

3 Calgary Attractions
Exercise 3
Emma buys a ticket to the Calgary Zoo for $12.00. She gives the cashier a $20.00 bill. How much change does she get?
Definition:

Attraction pricing: Calculating change for Calgary attractions and venues

Step 1: Identify the values

Cost = $12.00, Payment = $20.00

Step 2: Subtract to find change

$20.00 - $12.00 = $8.00

Step 3: Express as coins

$8.00 = 8 loonies OR 4 toonies

Change = $8.00 (8 loonies)
Final answer:

Emma gets $8.00 in change, which could be 8 loonies.

Applied rules:

• Decimal subtraction: $20.00 - $12.00 = $8.00

• Equivalent values: $8.00 = 8 loonies = 4 toonies

• Verification: $12.00 + $8.00 = $20.00 ✓

Calgary Solutions: Exercises 4 to 5
4 Calgary Market Shopping
Exercise 4
Alex buys fresh apples at the Calgary Farmers Market for $6.25. He pays with a $10.00 bill. How much change does he get?
Definition:

Local market transaction: Calculating change at Calgary's farmers markets and local vendors

Step 1: Identify the values

Cost = $6.25, Payment = $10.00

Step 2: Subtract cost from payment

$10.00 - $6.25 = $3.75

Step 3: Express as coins

$3.75 = 3 loonies + 3 quarters OR 15 quarters

Step 4: Choose simplest combination

$3.75 = 3 loonies + 3 quarters

Change = $3.75 (3 loonies + 3 quarters)
Final answer:

Alex receives $3.75 in change, which is 3 loonies and 3 quarters.

Applied rules:

• Subtraction: $10.00 - $6.25 = $3.75

• Multiple representations: $3.75 can be made with different coin combinations

• Verification: $6.25 + $3.75 = $10.00 ✓

5 Calgary Mall
Exercise 5
Maya buys a souvenir at the Calgary Tower gift shop for $8.50 and a postcard for $1.25. She gives the cashier a $20.00 bill. How much change does she receive?
Definition:

Multi-item purchase: Adding costs of multiple items before calculating change in Calgary stores

Step 1: Calculate total cost

$8.50 + $1.25 = $9.75

Step 2: Subtract total cost from payment

$20.00 - $9.75 = $10.25

Step 3: Express as coins

$10.25 = 10 loonies + 1 quarter OR 5 toonies + 1 quarter

Step 4: Choose simplest combination

$10.25 = 5 toonies + 1 quarter

Change = $10.25 (5 toonies + 1 quarter)
Final answer:

Maya receives $10.25 in change, which is 5 toonies and 1 quarter.

Applied rules:

• Addition: Total cost = $8.50 + $1.25 = $9.75

CALGARY COMPREHENSIVE SUMMARY: MAKING CHANGES
KEY DEFINITIONS (Calgary Style)
  • Cost: The price of an item you want to buy in Calgary (e.g., Calgary Tower ticket costs $15.00)
  • Payment: The money you give to buy something in Calgary stores
  • Change: The money you get back after buying something in Calgary
  • Canadian Coins: Penny (1¢), Nickel (5¢), Dime (10¢), Quarter (25¢), Loonie ($1.00), Toonie ($2.00)
  • Bill: Paper money in larger denominations ($5, $10, $20 bills)
  • Total Cost: When buying multiple items in Calgary, add all prices together
  • Equivalent Amounts: Different ways to make the same amount using Canadian currency
  • Making Changes: Calculating the correct change at Calgary businesses and attractions
CALGARY CORE PRINCIPLES & RULES
  • Basic Formula: Payment - Cost = Change (standard across Canada)
  • Canadian Coin Values: Penny = 1¢, Nickel = 5¢, Dime = 10¢, Quarter = 25¢, Loonie = $1.00, Toonie = $2.00
  • Always Subtract: Subtract the smaller number (cost) from the larger number (payment)
  • Verification Rule: Cost + Change = Payment (always check your answer!)
  • Multiple Items: Add all costs together before subtracting from payment
  • Grade 2 Level: Problems use amounts less than $25.00 with whole dollar and cent amounts
  • Simple Operations: Addition and subtraction within 100 cents
  • Calgary Context: Examples use real Calgary landmarks and prices
CALGARY STEP-BY-STEP METHOD
  1. Read Carefully: Find what the item costs and how much money was given
  2. Identify Numbers: Circle or highlight the cost and payment amounts
  3. Set Up Subtraction: Write payment - cost = change
  4. Calculate: Subtract the cost from the payment
  5. Express in Coins: Show the change using Canadian coins (loonies, toonies, quarters, etc.)
  6. Check Your Answer: Add cost + change to make sure it equals payment
  7. Calgary Context: Connect to local landmarks and businesses
CALGARY EXAMPLES FROM SIMPLE TO ADVANCED
  • Simple: Hot dog at Calgary Stampede costs $3.50, you pay $5.00 → $5.00 - $3.50 = $1.50 change (1 loonie + 2 quarters)
  • Moderate: Maple syrup at Farmers Market costs $4.75, you pay $5.00 → $5.00 - $4.75 = $0.25 change (1 quarter)
  • Advanced: Two items cost $8.50 and $1.25, you pay $20.00 → $8.50 + $1.25 = $9.75 total cost → $20.00 - $9.75 = $10.25 change (5 toonies + 1 quarter)
  • Grade 2 Challenge: Calgary Zoo ticket costs $12.00, you pay $20.00 → $20.00 - $12.00 = $8.00 change (8 loonies)
CALGARY TIPS & TRICKS
  • Count Up Method: Start with the cost and count up to the payment (easier than subtraction)
  • Use Real Canadian Coins: Practice with actual loonies, toonies, and other Canadian currency
  • Start with Largest Coins: When making change, use the largest coins first (toonies, loonies)
  • Check Your Work: Always verify by adding cost + change = payment
  • Convert Dollars to Cents: Sometimes it's easier to work in all cents
  • Visual Aids: Draw coins or use manipulatives to represent the problem
  • Practice Daily: Look for opportunities to calculate change while shopping in Calgary
  • Landmark Learning: Connect math to familiar Calgary locations
COMMON CALGARY PITFALLS TO AVOID
  • Wrong Operation: Don't add instead of subtract
  • Missing Items: Forget to add up multiple item costs
  • Incorrect Coin Values: Confusing Canadian coin values

Questions & Answers (Calgary Style!)

Question: I sometimes get confused when counting change at the Calgary Stampede. How can I make sure I'm getting the right amount back?

Answer: Great question! Here are some strategies to verify your change:

  • Add it up: Always add the cost and your change together to see if it equals what you paid.
  • Count up: Start with the cost and count up to what you paid.
  • Use Canadian coins: Practice with loonies and toonies to build number sense.
  • Draw it: Draw circles representing coins to visualize the problem.

Example: Hot dog costs $3.50, you pay $5.00. Change should be $1.50. Check: $3.50 + $1.50 = $5.00 ✓

Question: My child loves Calgary landmarks. How can I use local examples to help them learn making changes?

Answer: Great idea! Try these Calgary approaches:

  • Visit landmarks: Practice calculations at Calgary Tower, zoo, or farmers market.
  • Use local prices: Reference real Calgary attraction costs.
  • Connect to landmarks: "How much change would you get at the Calgary Stampede?"
  • Role play: Pretend to buy tickets to Prince's Island Park.
  • Field trips: Practice with actual transactions at local attractions.

Make math meaningful with familiar Calgary locations!

Question: I see loonies and toonies everywhere in Calgary. How do I use them when making changes?

Answer: Great question! Here's how to work with Canadian coins:

  • Loonie: Equals $1.00, so it's like having a dollar bill
  • Toonie: Equals $2.00, so it's worth two loonies
  • Count by ones: Loonies count as 1, toonies count as 2
  • Combine with quarters: 1 toonie + 2 quarters = $2.50
  • Use for large amounts: Toonies help with bigger change calculations

Practice with Canadian coins just like you would with regular dollars!
