macaroni or play money in place of real money, you will help your
children guess (estimate) and then figure out which is a better buy --10%
off or $10 off on items that are priced at $50, $100, or $120. Use each
bean or piece of macaroni to represent $1.
10% off on a $50 jacket - If a jacket is on sale for 10% off, we can
figure out the new price by using beans to represent real money. Make 5
piles of 10 beans each; take one bean (10%) from each pile. Count the
number of beans you now have in all of the piles: 50 beans less 5 beans =
45 beans. Translating beans into dollars, the new price of the jacket is
$10 off a $50 jacket- Figuring out $10 off is easy. Using a pile of 50
beans, take away 10 beans. Count the beans you have left -- 50 beans less
10 beans = 40 beans. $40 is the new price of the jacket. Which was the
best buy--10% off or $10 off?
This activity helps
your child understand math by developing a sense of numbers and by
practicing estimation. Using several real-life activities your child
will see how much math can be used in getting the best buy.
