2 quarters = ___¢

Adding money works just like adding numbers! 25¢ + 30¢: add the cents like 25 + 30 = 55, so 55¢. If your total reaches 100¢, that's $1.00!
Example: A pencil costs 25¢ and an eraser costs 30¢.
25¢ + 30¢ = 55¢ together.
Example: A sticker costs 60¢ and a card costs 40¢.
60¢ + 40¢ = 100¢ = $1.00!
Add each pair of prices.
25¢ + 30¢ = ¢
15¢ + 40¢ = ¢
35¢ + 25¢ = ¢
45¢ + 20¢ = ¢
Number Talk — Explain WITHOUT calculating.
A: 25¢ + 25¢ B: 25¢ + 35¢
Which total is bigger? How do you know without adding?
My thinking:
Toy A costs 49¢. Toy B costs 51¢. About how much do they cost together — is it about $1? Why?
My thinking:
Read carefully. Think about what is happening.
At the school store, Nora buys a bookmark for 35¢ and a pencil grip for 25¢. How much does she spend in all? Show your thinking.
Draw or write your thinking:
Total: ¢
