Count Coin Values by 2s, 5s and 10s

Use skip-counting relationships to find the value of collections of pennies, nickels, and dimes. Count paired pennies by 2s, nickels by 5s, and dimes by 10s.

Students also combine simple coin groups and use efficient counting order to determine collection values up to 120 cents.

๐ŸŽฏ What You Will Learn

Count paired pennies by 2s
Two pennies are worth 2¢, so pairs can be counted by 2s.
Count nickels by 5s
Each nickel adds 5¢ to the total.
Count dimes by 10s
Each dime adds 10¢ to the total.
Count simple mixed collections
Start with larger coin values, then add smaller ones.
For parents & teachers — standards alignment: Texas Grade 1 TEKS 1.4(C) directly requires students to use relationships to count by twos, fives, and tens to determine the value of a collection of pennies, nickels, and/or dimes. This lesson follows that expectation closely: paired pennies can be counted by 2s, nickels by 5s, and dimes by 10s; in mixed collections, pennies may also be added by ones when needed. The Grade 1 collection value remains within 120 cents. Quarters were introduced in Lesson 30, but they are not part of the core TEKS 1.4(C) collection-counting scope used here. Common Core Grade 1 does not include an equivalent standalone coin-counting standard; Common Core money work appears explicitly in Grade 2 CCSS 2.MD.C.8.

๐Ÿง  Key Vocabulary

coin collection — a group of coins whose total value you want to find.
paired pennies — pennies grouped two at a time; each pair is worth 2¢.
nickel — a coin worth 5¢.
dime — a coin worth 10¢.
total value — the number of cents all the coins are worth together.
skip count — add the same amount repeatedly while counting.

๐Ÿช™ Three Useful Counting Strategies

Paired Pennies → by 2s
2¢ 4¢ 6¢ 8¢
Nickels → by 5s
5¢ 10¢ 15¢ 20¢
Dimes → by 10s
10¢ 20¢ 30¢ 40¢
Important: a penny is worth 1¢, not 2¢. We count paired pennies by 2s because each pair contains two 1¢ pennies. A nickel is worth 5¢, and a dime is worth 10¢.

๐Ÿ”„ Count Mixed Collections Efficiently

For a simple mixed collection, it is often easier to begin with dimes, then count nickels, and finish with paired pennies or single pennies. Keep track of the running total in cents.

1. DimesAdd 10¢ for each dime.
2. NickelsAdd 5¢ for each nickel.
3. PenniesAdd penny pairs by 2¢, then any single penny by 1¢ if needed.
Connection to Lesson 29: the same skip-counting patterns are now being used with real coin values. The counting amount must match the value being added.

15. Each penny pair adds 2¢, each nickel adds 5¢, and each dime adds 10¢, so the skip-counting amount matches the value added each time. If one penny remains unpaired, add 1¢ at the end.

๐Ÿ’ก Common Mistakes to Watch For

Thinking one penny is worth 2¢
One penny is 1¢; only a pair of pennies is 2¢.
Counting nickels by 2s
Each nickel is worth 5¢, so count nickel values by 5s.
Counting dimes by 5s
Each dime is worth 10¢, so count dime values by 10s.
Mixing the running total
In a mixed collection, keep one total and add each new coin value to it.
What comes next: Lesson 32 focuses on Needs, Wants, Saving, Spending & Giving.
