How this changes by age
Pre-K (ages 3–4)
Meet the coins! Learn to identify pennies, nickels, dimes, and quarters. Sort real or play coins and practice naming their values.
Steps
- Spread out a handful of mixed coins (real or play money).
- Introduce each coin by name and value: penny (1 cent), nickel (5 cents), dime (10 cents), quarter (25 cents).
- Sort coins into 4 groups by type. Count how many of each.
- Play 'Find the Coin': describe a coin and have your child find it.
- Put coins in order from least value to most value.
- Tell a grown-up one thing that surprised you.
Learning objectives
- Identify pennies, nickels, dimes, and quarters by sight
- Know the value of each coin type
- Sort and classify coins by type
Kindergarten (ages 5–6)
Count groups of coins to find their total value. Set up a pretend store and practice buying items with exact change.
Steps
- Practice skip counting by 5s (nickels) and 10s (dimes) to count coin groups.
- Count mixed groups of coins: start with the highest value coin and add on.
- Set up a pretend store with 5 items priced under 50 cents.
- Give your child a pile of coins. Can they pay the exact price for each item?
- Make change: if an item costs 15 cents and you pay with a quarter, how much change do you get?
- Tell a grown-up one thing that surprised you.
Learning objectives
- Count mixed groups of coins to determine total value
- Skip count by 5s and 10s using coins
- Make simple purchases with exact change
Early elementary (ages 6–8)
Solve real-world money problems: making change, comparing prices, budgeting, and understanding dollars and cents notation.
Steps
- Practice making change from $1.00, $5.00, and $10.00 using the count-up method.
- Compare prices from a pretend catalog: which item is the best deal? How much more does item A cost than item B?
- Given a $20 budget, choose items from a list and calculate if you can afford them all. What's your change?
- Write 5 money word problems for a family member to solve.
- Calculate sales tax at 10%: if an item costs $4.50, what's the total with tax?
- Keep a spending log for one real errand and calculate the total spent.
- In one sentence, tell a parent or sibling what surprised you today.
Learning objectives
- Make change using the count-up strategy
- Solve multi-step money word problems
- Apply money math to real-world budgeting situations
Upper elementary (ages 8–10)
Master advanced money concepts: calculating discounts and sales tax, comparing unit prices, creating budgets, and understanding profit/loss.
Steps
- Calculate 5 discounts: a $60 item at 25% off, a $45 item at 30% off, etc. What's the sale price?
- Compare unit prices: which is a better deal, a 12-oz box for $3.60 or a 16-oz box for $4.48?
- Create a monthly budget for a pretend allowance of $50: savings (20%), spending, and giving categories.
- Run a pretend business: if supplies cost $15 and you sell 20 items at $2 each, what's your profit?
- Research: compare the price of 5 grocery items at two different stores. Which store is cheaper overall?
- Calculate compound scenarios: buy 3 items with a 15% discount, then add 8% sales tax.
- In one sentence, tell a parent or sibling what surprised you today.
Learning objectives
- Calculate percentages for discounts and tax in money contexts
- Compare unit prices to determine best value
- Create and manage a simple budget with multiple categories
Safety and evidence note
Read the full activity before beginning. An adult should supervise tools, heat, food, outdoor work, movement, and experiments as appropriate. Completion records that the activity was done; the child’s explanation, work sample, photo, or demonstration is stronger evidence of learning than a completion check alone.
