Massachusetts Grade 1 Math

Which coin collection has more value?

Milo has six pennies. Asha has one nickel and two pennies. Which collection has more value, and how much more? Use coin pictures or supervised classroom manipulatives. Count the number of coins separately from their total value; the coins are not all worth the same amount.

Explain the solution

Six pennies have a value of six cents because each penny is worth one cent. Asha’s nickel is worth five cents, and her two pennies add two cents. Her three coins therefore have a total value of seven cents. Asha has one cent more even though Milo has more individual coins. Exchange the nickel for five penny pictures to make the comparison visible: Asha’s collection now represents seven one-cent units. Match six of them with Milo’s six units; one remains. The exchange changes the representation, not the collection’s value.

Notice the reasoning

If a child chooses Milo because six coins is more than three coins, acknowledge the correct count and ask a different question: how much is each coin worth? If the child treats the nickel as one cent, replace it with five penny pictures and discuss equivalence. Avoid counting a pictured exchange as additional money. Keep values within 100 cents and observe whether the student recognizes coins, combines values, and explains the comparison. This small activity addresses part of the Massachusetts money expectation; it does not cover every U.S. coin or every possible money problem.

Try a related task

Build another collection worth seven cents using only pennies and nickels. Compare it with the original seven-cent collection and explain why equal values can use different numbers of coins. Then introduce a dime with ten penny pictures and ask for an equivalent collection. A teacher can change the amounts while retaining a visible model before expecting mental calculations. Use drawings rather than real coins where small objects are unsuitable, and keep this math exercise separate from making purchases or handling anyone’s actual money.
