Money and Making Change — Answer Key
Part A: Fix the Sentence
Each sentence has an error. Rewrite it correctly on the line.
1. Fix the sentence:
A half-dollar coin are worth 50 cents in Grade 3 money work.
Corrected: A half-dollar coin is worth 50 cents in Grade 3 money work.
One half-dollar is singular, so it needs is, not are.
2. Fix the sentence:
Two quarter makes 50 cents on a Grade 3 money chart.
Corrected: Two quarters make 50 cents on a Grade 3 money chart.
Two is plural, so quarter must become quarters here.
3. Fix the sentence:
My pocket have one half-dollar and one dime in Grade 3 class.
Corrected: My pocket has one half-dollar and one dime in Grade 3 class.
Singular subject pocket needs the verb has, not have.

Write the missing word or number on each line.
1. A half-dollar coin is worth 50 cents in Grade 3 money lessons.
Half of one dollar (100c) is 50 cents exactly.
2. One quarter plus two dimes plus one nickel equals 50 cents.
25 + 10 + 10 + 5 = 50 cents in total.
3. Five dimes together are worth 50 cents in Grade 3 work.
Each dime is 10c, so 5 dimes make 50 cents.

Two quarters equal 50c, which is a half-dollar coin.

True False
25 + 5 = 30 cents, not 50, so the claim is false.
