Coin Value Math

Overview

Today students practice identifying coins and counting money to find the total value of a small set of coins, with a focus on adding cents up to one dollar. This builds number sense for teen/ten relationships and connects counting to written numerals and representations.

Learning intentions

• Students will be able to identify common coins (pennies, nickels, dimes, quarters) by value.
• Students will be able to count the value of coin sets by ones or using known coin jumps (5s and 10s).
• Students will be able to write a numeral total for up to 100 cents (one dollar).
• Students will be able to model adding coins using touch/counters and drawings, then explain the strategy.

Success criteria

• I can correctly name the value of each coin I see.
• I can count or add coins to find the total value.
• I can write the total number of cents (and say “one dollar” when appropriate).
• I can explain how I got my total using tens/ones ideas or counting.

Curriculum links

• Number and Operations in Base Ten: count to 120, read and write numerals, and represent a number of objects with a written numeral.
• Measurement and Data: express length using units (as a connector for “units/spans” thinking about counting units of money).
• Number and Operations in Base Ten: understand that 11–19 are a ten and ones (to support teen number awareness if totals land in that range).
• Number and Operations in Base Ten: add within 100 using models/drawings; add tens and ones; sometimes compose a ten.

Lesson structure (15 minutes total)

1. 0–3 min · Hook (Coins Touch Routines). Teacher places four coin samples (penny, nickel, dime, quarter) in a “coin touch box” and asks, “How can you tell which coin it is by touch?” Students feel one coin at a time, then turn and tell a partner its value and why (texture/size/shape clues).
2. 3–6 min · Quick whole-group identification. Teacher shows 3 coins on the board one at a time and says, “Name the coin and its value.” Students answer chorally and individually, repeating the value aloud (1, 5, 10, 25).
3. 6–10 min · Model adding coins to one dollar. Teacher uses a small mat with two “amount spots” labeled “tens” and “ones” (or “10 and more” and “the rest”), plus counters/drawings. Teacher demonstrates: “We have a dime and three pennies. What is the total?” Teacher counts on fingers from 10 (dime) and then adds pennies to reach 13, showing the numeral. Students repeat with a teacher-led coin set, using touch rigs/counters (slide coins into the mat spots, or cover with tokens).
4. 10–13 min · Student practice with worksheets (value up to 1 dollar). Teacher hands out a “Coins: Touch, Match, Add Up to 100 cents” worksheet. Students complete 2–3 problems: identify the coins in a row and write the total cents (and a “$1” label only if they reach 100). Students are encouraged to draw coin circles or place small tokens in groups of 10 when possible.
5. 13–15 min · Share + exit check. Teacher collects quick responses: students show their first completed total on their desk. Teacher asks one student, “What counting step did you use?” Students answer with a short explanation (“I started at 10” / “I counted by 5s” / “I grouped into tens, then added ones”). Teacher gives a final one-question oral check: “What is 1 nickel and 2 pennies?” (expected 7).

Resources

• Large, smooth, tactile coin images or actual coins (pennies, nickels, dimes, quarters)
• “Touch riggles” / textured coin tactile cards or a labeled coin touch box
• Small counters or classroom tokens for ones and groups of ten
• A teacher coin mat with two areas: “tens” and “ones” (or “10s” and “ones”)
• Student worksheets: coin identification + add-up-to-100-cents problems
• Pencil, crayons, and a small whiteboard or scrap paper for showing totals

Assessment

• Formative checks during hook: students name coin values from touch and match to the correct coin
• Formative checks during modeling: students correctly count and produce the total numeral for the shared set
• Exit ticket (oral or quick written): totals a simple set (e.g., nickel + 2 pennies) and states the value confidently

Differentiation

• Support: provide a coin value card (1/5/10/25) on the desk; allow students to use grouped counters (10-stick bundles) before writing totals; sentence starters: “I started with…” “Then I added…” “My total is…”
• Support for ESL/SEN: model one example slowly, keep coin choices limited to pennies, nickels, dimes first; use visual number lines labeled 0–25 or 0–50.
• Extension: offer a challenge worksheet problem that includes four or five coins totaling between 30 and 99 cents; ask students to explain whether they used “counting by 5s” or “making a ten.”
• Attention/engagement: for the touch routine, rotate roles so each student gets multiple turns, but keep sets to no more than 6 coins per problem to match working memory in 1st grade.
