A Plethora of Ideas for
RealLife
Math

Beth, Wendy, and Amy
(for all ages)
Here are just a few suggestions for
reallife math. But keep in mind that what you do and how you
live will determine a lot of what is "real" for you!
~ My father had me figure out his bowling
average for a whole year when I was in high school! Another idea could
be a favorite ball player's batting average, or other stats for a
sports team.
~ Balancing a checkbook  YOUR checkbook. Not only will this improve
math skills, but will also teach some valuable lessons: how to do it,
how much an income is realistically, where it all goes, how little is
left for luxuries ~smile~, etc.
~ Grocery shopping  Again, valuable life lessons, but also how to
find the best bargain, price per portion, unit pricing and so on. Have
your child keep a price book so he/she can tell if a sale is a real
bargain. (There are lots of webpages devoted to price books, do a
search to find several. Another is
http://www.organizedhome.com ) Eventually, you might even
give your teen the shopping list and let them do the grocery shopping.
~
My fourth grader is constantly finding things she wants to buy, then
figuring out how many weeks she'll need to save her allowance in order
to buy it.
~ "Buying" a stock (or even really doing it, just one share now that
they are so low in price!) and keeping track of how it does. Figuring
out interest on a savings account or CD. How much would interest add
to a car loan?
~ A job of some sort... mowing lawns, or shoveling driveways,
babysitting or whatever, figuring out 10% for tithe, deciding what
percentage goes in the bank, etc.
~ When Christmas is getting close... how much will your teen
have to spend on gifts? How many people to give gifts to? Average
amount to be spent on each person? (My daughter and I are working on
two baby quilts as Christmas gifts, and it's a wonderful exercise in
math. Now that we have the patchwork done, we need to figure out how
much fabric to use for the borders  we'll figure out how to cut that
from a piece of fabric and how much we'll need to buy.)
~ Cooking/baking are also wonderful experiences for reallife
math... we've even made half a box of macaroni and cheese,
requiring the dividing of all the ingredients, including that cheese
powder.
Just some simple examples, but some could be stretched over a long
period of time to be an ongoing lesson or project.
Joyfully in Christ,

Barb has a
great article called "What
Is RealLife Learning?"
that's helped me a TON to see and understand how much learning
can take place in our home without a "text." Every time
I
reread it I am just so encouraged. Basically, any activity
listed in Barb's article that includes using numbers would be
math.
Melanie
~ Doubling or tripling
a recipe, or cutting one in halves, thirds, or fourths. (These
things challenge me.)
~ We did real math with a pillow that is over sized. We needed to
make a pattern to fit that particular pillow. We've had to do that for
curtains too. Can't find a pattern just like we want, so
we have to adjust it.
~ Many people use coupons when shopping. How much did you save with
your coupons? Did your coupon encourage you to buy thing you don't
normally buy? Did it encourage you to buy something you don't need?
Could you have bought generic brand for less? Sometimes the generic
brand really doesn't taste as good, is the price difference worth the
taste difference?
~ Keep track of sales in
stores to decide what would be the best buy. How much does it
cost to run from store to store to hit all those sales, would you save
money in gas and wear and tear on your car if you just shop at one
store?
~ Figure out what the cost of that shirt will be when it is 30% off
regular price. Or adding sales tax.
~ Shopping on a budget, setting up the budget and deciding how much
meals will cost for the week. then stay within that budget. see how
realistic were you in your original estimate.
~ How much fertilizer will you need to cover your lawn? How many
square feet is your lawn? What will the price per sq. ft be?
~ What are your car's monthly costs? Gas, insurance, maintenance?
How many miles per gallon does your car get?
~ Put together a lemonade stand, how much do you need to charge per
cup and still pay for the lemonade and supplies you used, plus make a
little profit?
~ How much lumber will it take to make a deck, doghouse, or extra
room on the house? Or how much fencing will we ned to fence in the
dog, or the garden...
~ Draw up plans for a dream house, and furnish it. How much
will each cost?
~ For real little ones, you can figure out how to cut up your 2
apples to feed all 4 people you have for lunch. or how should we cut
the pizza so every one gets an even number of pieces? Or if I cut the
sandwich in 4 pieces, 1 piece = ¼, 2 pieces = ½, 3 pieces = ¾.

(To the above ideas from Beth, Lauri responded: Beth
your examples were WONDERFUL!! These are the very things many high
school graduates can't do. Not only can't they do these things,
they can't necessarily figure out *how* to do them! There is a
desperate need for this type of education in schools, Praise God that
my children receive this education by "osmosis" here at home!)
~ How about making
change!? I can't tell you how many people I have come across who
would not be able to count out your change to you if their computer
went down! ~
Wendy
Something we just
started with our 11yearold daughter is we got her a bunch of
chickens and she is keeping track of the expenses vs. (future)
income She is thrilled whereas some children would not be very
excited about chickens. It's about finding the delight of your child's
heart and connecting it to the things they need to learn.

Amy shared:
~ Estimating could easily top the list of
"important everyday math skills." About how much money do you
have to shop with? About how much will three of these cost?
Will I have enough left over for that pie, or should I plan on making
one myself from what I have at home? About how many apples will
that take? We need new bookshelves...how long should they be?
How many supports will we need? What about mollies or screws for
hanging them? How many feet of lumber will we need, and how can
we plan so that we waste the least
amount of wood when we cut it? How big is that garden
area, and how much compost will we need to make to cover it over the
winter? And don't forget miles per gallon... how do you
figure that, and why does it matter? Maybe you can come up with
a house project such as painting your daughter's room, or putting up a
wallpaper border, or making a comforter. That would give lots of
reallife practice with estimating, multiplying, dividing, etc.
And it has a reallife motive, not just "do it for math class."
~ The example of unit cost (cost per ounce, pound, or whatever) is
another excellent example. I've taught my sons and daughter to
check the unit price at the store, not just to grab the biggest box
(or the smallest box) or the bulk foods. However, the boys still
need more work on estimating the unit cost for themselves, for those
lovely times when one size product is marked "per ounce" and another
size of the same product is marked "per pound" or "per quart" or even
"per EACH" (now, how helpful is THAT, I ask you?! LOL). How many
loads of laundry can I do with this box of soap? So what's the
cost per load?
~ Budgeting is another important math (and critical thinking) area,
too! With your daughter, write a list of bills, offerings,
savings, etc. due each month (and for us, we need to know WHEN they
are due, as well, since we don't have regular paydays). A balance of
$500 in the checking account does not necessarily mean we can go out
for pizza... Is that money already spoken for/accounted for?
Of course, this will lead into good discussions of choices,
stewardship, blessing of others, savings both longterm and
shortterm, even interest and investments and loans and the evils of
abused credit....oh, sorry, talking about myself here! ;)
But I'd start with the bare bones of daily/monthly money planning,
sharing WHY you make the choices you make, and (in my case again) the
consequences of poor past choices (gulp).
(Click
here to see the "Finance Record" I made up for Carlianne.
She started using it a year ago (at age 15) and still faithfully keeps
it up. After every shopping outing, she can be found diligently
entering all her figures ~ and balancing!)
And all of this "life learning" will "count" under Consumer Math, or
General Mathematics, or... ~Amy in WA

This
weekend my daughter made a cake for church and cupcakes. She had to
measure everything and double the recipe as it was a double batch.
I taught her about fractions. Yippee!!!!!!!! ~ Cindy O.
And one last thought from Amy to close
this discussion of "reallife" learning with...
"The
"real world" is full of adults who cannot make change without a
machine telling them the exact amount to give back, who cannot
balance their checkbook, who think that "the more they spend,
the more they save," (as the ads tell us) and so on. I wouldn't
worry too much about what the socalled "real world" does!
LOL 
Here is a little bonus...
How to
Count Back Change
to a Customer
One mom said: "I can't count how many times I have gone in a store during a storm or other "computer down time" and the checkers can't even count out the change without their computers or calculators!" Exactly!! And that's yet another great "math function" to know! In fact, you don't even have to know to subtract in your head, you just need to know the operation! ~ which really is only counting UP! ~ by one's, five's, ten's and then quarters. (In case you don't know, all you do is start with the amount of purchase... Let's say the thing cost $2.32 cents, and they gave you $10. OK, you just say "32" and then count pennies saying "33, 34, 35" at which point you've hit a five, so then you skipcount, pulling out a nickel saying "40," then skip count by 10, pulling out a dime, to 50, then two more quarters take you up to three dollars. Then pull out one dollar ~ $4 ~ another dollar ~ $5. And then finally a $5 bill takes you up to $10! So you just start with the amount of the purchase and count your way UP until you get to the amount paid. I enjoy this SO much that when people pay us in cash at our book table, I actually INSIST on doing this, saying "This is just SO cool! Let me give you your change properly!" I'm sure they think I'm weird, but so what else is new?!?!?! ;D
