Change is the money you get back when you pay more than the price. Strategy: count UP from the price to what you paid.
Example: A toy costs 35¢. You pay with 2 quarters (50¢).
Count up: 35¢ → 40¢ (that's 5¢) → 50¢ (that's 10¢ more). Change = 5 + 10 = 15¢.
Count up from the price to the amount paid. Write the change.

Price: 30¢ Paid: 50¢

Two Ways — Find the change two different ways. Do they match?
Price 45¢, paid 60¢
Strategy 1 — count up:
Strategy 2 — subtract 60 − 45:
Change: ¢
Price 25¢, paid 50¢
Strategy 1 — count up:
Strategy 2 — subtract 50 − 25:
Change: ¢
