Topic: Money
How can money be
used to help teach fractions, decimals, and percents, and ratios: Money can
be used to teach math in an agglomeration of ways. We know that one quarter is
¼ of a dollar, a time is 1/10, a nickel is 1/20, and a penny is 1/100. This
information can be used as a fraction (as shown) or a decimal (quarter= .25,
dime= .1, nickel= .05, and a penny= .01). By turning the fractions into
decimals they can then be turned more easily into percents by multiplying by
100 (.25= 25%, .1= 10%, and so on). These can also be turned into ratios, if
you are referring to nickels and pennies a ratio could look like this: for
every 5 pennies there is one nickel so the ratio is 5:1, or 5/1, or, 5 to 1.
What are some
activities that can be used:
Strategies
for Teaching Money
Another
activity that would be helpful for student is the counting money activity. This
activity is aimed for mostly kids in the second grade. You need 8 plastic cups,
a sharpie, and plastic or real coins. On each cup write a different money
amount that is less than or equal to a dollar, then have each child figure out
how many of each coins are needed to find the amount written on the cup. This
helps children learn the value of money with the dollar being a whole. Also,
money is almost always shown as a decimal so this activity would help students
learn how decimals work, and how anything behind the decimal point is less than
one.
In
another activity for fifth or sixth graders, you could give them a worksheet
with items and the prices of the items and then tell them that there is a
certain percent tax on those items and have them figure out how much money the
tax is and how much extra they would owe after tax. This would help them
familiarize with percents and how they connect to the real world. This would also
help them with decimals, because as I said before, money is shown in decimals.
An
activity that could be used to help with fractions is, you could put an
assortment of coins in front of them, let’s say you put 3 nickels, 2 pennies,
and 5 quarters, you could ask how many pennies, nickels, and quarters out of
ten are there? The answer would like this: Pennies= 2/10, Nickels= 3/10, and
Quarters= 5/10. Once they start to get good at identifying the fractions you
could make it harder by making the denominator a larger number, such as 20, 30,
50, etc. This activity would be for
first and second graders.
