Making Cents of the Coinage Act May 18, 2015 04:30
In Excel Math, students learn to add and subtract various monetary units. Today we're giving you a free math worksheet of coin images you can use with your own students. Click here to download the PDF file. Give a page of coins to each of your students. Have each student cut out the coins along the broken lines and stack them according to their value (all pennies in one stack, nickels in another, etc). Use the rectangle of coins at the bottom of the worksheet to talk about each coin, its distinguishing features, and how much it is worth:

Let your students place the stacked coins on top of their matching pictures. Now have them find the one coin worth 25¢. Next have them find three coins whose sum equals 25¢ (two dimes and a nickel). Continue practicing any skills your students need to review (making change, adding and subtracting coins of various values, etc.).
Now point out additional features of the coins. Help your students identify the faces of presidents shown on the coins: Lincoln - penny, Jefferson - nickel, Roosevelt - dime, Washington - quarter, Kennedy - half dollar (shown above).
Let the students find the date on each coin and guess what it means. (the year the coin was minted) Have your students take turns reading the words on each coin aloud. Explain that liberty means freedom. At the time the coins were first introduced, not all people in the United States were free. Some people still owned slaves, women did not have the same rights as men, etc. Point out that the words on a quarter are quarter dollar since 25¢ is a quarter (or one-fourth) of one dollar. (We'll look at monetary equivalents and equivalent representations of fractions next week.)
Some of your students may not be aware that there are also dollar and half-dollar coins. Show them a few of the images on those coins:
Ask your students if they can tell where the coins were made. You can tell where your coins were minted by looking at the small letter under the president's portrait on the coin. (If the coin was minted before 1968 the letter will be on the other side.) The D is for Denver, the S is for San Francisco, and the P is for Philadelphia. Mint marks date from the days of ancient Greece and Rome. The practice was begun in the United States by an Act of March 3, 1835, which established the first branch mints in this country.
