Skill: Count simple mixed coin collections

Explanation and Free Practice Resources

A mixed coin collection is quantified by combining the values of pennies, nickels, dimes, and quarters, rather than counting the number of coins; the total is expressed in cents, typically for collections totaling no more than 100 cents. Reasoning includes skip-counting equal denominations and adding groups, recognizing that different combinations can have the same value and that the order of coins does not affect the total.

Detailed Explanation: Count simple mixed coin collections

To find the value of a mixed coin collection:

  1. Find the value of each kind of coin.
  2. Count equal coins by skip-counting.
  3. Add the groups together.
  4. Write the answer in cents.

Example: You have 2 pennies, 1 nickel, 2 dimes, and 1 quarter.

  • 2 pennies: 1+1=21+1=2 cents
  • 1 nickel: 55 cents
  • 2 dimes: 10+10=2010+10=20 cents
  • 1 quarter: 2525 cents

Now add the groups:

2+5+20+25=522+5+20+25=52

The coins are worth 52 cents altogether. The order of the coins does not change the total.
