Coin values and counting same coins

Know the value of a penny, nickel, dime, and quarter, and count a pile of same-value coins by skip counting.

Each coin has a value: a penny is 1 cent, a nickel is 5 cents, a dime is 10 cents, and a quarter is 25 cents.

When all the coins in a pile are the same, skip count by that coin's value instead of counting one by one. Five dimes: 10, 20, 30, 40, 50 cents.

📋 For the teacher
Teach it (10–15 min):
  • Use real coins if you have them -- the size and color differences (and the fact that a dime is smaller than a penny) are worth noticing out loud.
  • Drill the four values (1, 5, 10, 25) until they are instant -- everything else this unit builds on knowing them cold.
  • Always skip count same coins in that coin's own value, not by ones.
  • Point out prices on real receipts or store signs around the house.
Talk about it:
  • What is the value of each of our four coins?
  • Why do we skip count instead of counting pennies one at a time for a pile of dimes?
  • Which coin is worth the most? Which is worth the least?

Mastery looks like: They name all four coin values instantly and count a same-coin pile correctly by skip counting.

Common stumbles: Confusing a dime's small size with a small value; skip counting by the wrong number for the coin shown.
