Building Understanding and Excitement for Children
Need to go food shop-
ping? Why not turn it into
an opportunity for your
child to practice what
he’s learning in math.
Here are some ideas.
Weigh and multiply.
Fruits and vegetables are
often sold by the pound.
Ask your youngster to
compute how much your
produce will cost. For
example, say you want 6
bananas and they cost 49
cents a pound. He would
weigh them and multiply their weight by
the cost per pound (2 lb. x 49 cents =
98 cents) to get the total cost.
Comparison shop. Let your child help
you save money and learn to be a better
consumer. Ask him to read unit-pricing
labels on shelves to find the best value
(8 cents per ounce for one brand of
pasta sauce vs. 13 cents per ounce for
another brand). Or he can look for the
better deal: one box of cereal for $2.79
Habitat for rent
Help your child think
about what animals need to survive
(shelter, food, water). Then, have her
choose an animal (monkey) and write
a classified ad for a home that will
meet its needs. Example: “Tall tree
in a tropical rain forest. Large river
nearby for drinking. Plenty of leaves,
fruit, and insects to eat.”
Counting practice
Have your youngster practice count-
ing by 10s—but start at a number
that doesn’t end in zero. For instance,
begin at 787 and count by 10s (787,
797, 807). Try other numbers, too.
Examples: Count by 3s, starting at 52
(52, 55, 58), or by 5s, starting at 92
(92, 97, 102).
Book picks
Hotel Infinity is fully booked, but
there’s always room for more. Read
The Cat in Numberland (Ivar Ekeland)
for a clever introduction to infinity.
Learning about the solar system is
fun when planets tell the story them-
selves. Dan Green’s Astronomy: Out of
This World! contains fascinating facts
and details along with cartoon illus-
trations your child is sure to love.
Worth quoting
“Wondering is the seed of genius.”
William Mocca
Q: Why did the man water only half
of his lawn?
A: Because he
heard there
was a 50 per-
cent chance
of rain.

Just for fun
Look at me!
Help your youngster learn about the science of
optics with this mealtime activity.
Have her look at herself in a clean spoon.
What happens if she looks in the bowl of the
spoon? (She’s upside down.) What happens on
the other side? (She’s right side up.)
Next, have her bring her finger toward the
spoon and watch what happens on each side. The
bowl (the concave side) will magnify her finger, or
make it look larger. The back (the convex side) will make
her finger look smaller. Ask your child how scientists might
use this information to make eyeglasses, cameras, or
telescopes.
Tip: She can remember which side is which by thinking of concave as “caves in.”
or two boxes for $5? ($5 ÷ 2 = $2.50
per box, so you’ll save money buying
two boxes and storing one for later.)
Estimate the total. Ask your youngster
to predict your total bill by keeping track
of what you put in your cart. With each
item, he should check the price and
round it up or down to the nearest dol-
lar. As you go, he can keep a running
tally on paper, in his head, or on a calcu-
lator. At checkout time, see how close
he came.

What’s the angle?
Learning about angles is an important
step in understanding geometry. Try these
suggestions with your youngster:
●● Help her use her arms to demonstrate
angles. For a right angle, she can stretch
her left arm straight up and her right arm
straight out to her side. An acute angle is
smaller, so have her move her arms closer
together. And an obtuse angle is larger than a
right angle, so she should move her arms wider.
●● Next, see how many angles your child can find in the alpha-
bet. Have her print all 26 uppercase letters on a large sheet of
paper. With different-colored
markers, have her mark right
angles (one in “L,” for exam-
ple), acute angles (three in
“A”), and obtuse angles (two
in “X”).
●● Together, look for angles in
the real world. Right angles will
be easiest to find—they’ll be in
corners of rooms where one wall
meets another, on window frames,
or at the edge of a square sandbox. But
your youngster will also be able to find
angles that are acute (spokes in a bicycle
wheel) and obtuse (a door that’s wide open). Suggest that she
make a three-column chart (name of object, type of angle,
sketch of the angle) to record her findings.
How many times
can your youngster fold a piece of paper
in half? She will find out with this sur-
prising activity.
 Give her a piece of notebook paper,
and ask her to predict how
many times she can fold
it in half. Then, have her
test her prediction by
folding the paper in
half again and again
until it won’t fold
anymore. She’ll dis-
cover she can’t fold it
more than 6 times.
Learning
math words
My son Kaiden
struggles with vocabulary. And since he’s
learning so many new math words this
year, like circumference and integer, this
problem was affecting his math work.
I talked to Kaiden’s teacher, and she
thought it would help to post the words
where he could see them. She suggested
that he write each word on an index card
and illustrate it.
Kaiden and
I talked about
what each
word reminds
him of. For
instance, car
tires help
him remem-
ber that circumference is the distance
around a circle, so he drew a car with
tires on his circumference card.
We hung the cards on the refrigerator
so he could see the words every day.
Once he masters a word, we take it down
and add it to a pile on the counter. By
associating the math words with some-
thing meaningful to him, he has been able
to remember them more easily in class.
And watching his stack of words grow
seems to be giving him confidence.
Save your breath
Your child can inflate a
balloon without using his breath. A chemical
reaction will do the job for him!
You’ll need: empty plastic soda bottle
(20 fl. oz.), 1
–4 cup water, 1 tsp. baking soda, uninflated balloon, lemon juice
Here’s how: Have your youngster add the water and baking soda to the bottle,
close the cap, and swirl it around until the water is cloudy. Then, help him stretch
out the balloon and place the opening over the top of the bottle, leaving a small
space. He should very quickly add a squirt of lemon juice, seal the balloon com-
pletely over the bottle, and shake lightly.
What happens? The balloon inflates.
Why? When you mix an acid (lemon juice) with a base (baking soda), they
create carbon dioxide. The molecules spread out as the gas forms, pushing against
the walls of the balloon and causing it to inflate.
Paper folding
Have her try again with different sizes
and types of paper (tissue paper, paper
towel, newspaper). No matter the size or
kind of paper, she won’t be able to fold it
more than 6, 7, or 8 times.
Ask your child if she can
figure out why. Hint: It has to
do with doubling. The first
time she folds the paper,
she’ll have 2 layers. The
next time, 4 layers, and
so on…until 8 folds =
256 layers. The paper
simply becomes too
thick to fold again.

The Food Budget #1
Addition and subtraction
A budget is a plan for spending money. Many people plan how much money they
want to spend for food each week. They try not to spend more than the amount in
their budget.
Example: Mary Rose’s food budget is $175 per week. So far she has spent $101.
Problem: How much does she have left for the rest of the week?
Solution: Amount in budget: $175
Subtract the amount spent –
1. Tony planned to spend $100 for food this week. On Monday he spent $22 and on
Thursday he spent $52. How much money does he have left for the week?
____________________

$74
She has $74 left.
Directions: Answer the questions below.
2. Kate’s food budget for the month is $700. The first week she spent $189, the second
week she spent $200 and the third week she spent $150. How much did she spend?
___________ How much does she have left for the last week? __________
3. Last week Karen spent $121.35 on food for her family. She only has $200 to spend
every two weeks. How much does she have left to spend? __________
4. Mike and Lisa try not to spend more than $150 per week on groceries (including
going out to eat). Mike spent $84 on groceries and Lisa spent $23. They both went
out for lunch on Wednesday and spent $30. How much money do they have left for
groceries or dining out? ________________

Estimating Your Groceries #4
Estimation, multiplication and addition
Usually when we go to the grocery store we don’t have a calculator with us. We
usually estimate how much things will cost.
Part 1: Emily has $60 for grocery shopping. When shopping, Emily estimates the total
amount of the groceries. To estimate, round each item to the nearest dollar. Keep track
of the running total to see if Emily has enough money. The first one is done for you.

  • 2.  
  • 3. © 2011 Resources for Educators, a division of CCH Incorporated Building Understanding and Excitement for Children Need to go food shop- ping? Why not turn it into an opportunity for your child to practice what he’s learning in math. Here are some ideas. Weigh and multiply. Fruits and vegetables are often sold by the pound. Ask your youngster to compute how much your produce will cost. For example, say you want 6 bananas and they cost 49 cents a pound. He would weigh them and multiply their weight by the cost per pound (2 lb. x 49 cents = 98 cents) to get the total cost. Comparison shop. Let your child help you save money and learn to be a better consumer. Ask him to read unit-pricing labels on shelves to find the best value (8 cents per ounce for one brand of pasta sauce vs. 13 cents per ounce for another brand). Or he can look for the better deal: one box of cereal for $2.79 Habitat for rent Help your child think about what animals need to survive (shelter, food, water). Then, have her choose an animal (monkey) and write a classified ad for a home that will meet its needs. Example: “Tall tree in a tropical rain forest. Large river nearby for drinking. Plenty of leaves, fruit, and insects to eat.” Counting practice Have your youngster practice count- ing by 10s—but start at a number that doesn’t end in zero. For instance, begin at 787 and count by 10s (787, 797, 807). Try other numbers, too. Examples: Count by 3s, starting at 52 (52, 55, 58), or by 5s, starting at 92 (92, 97, 102). Book picks Hotel Infinity is fully booked, but there’s always room for more. Read The Cat in Numberland (Ivar Ekeland) for a clever introduction to infinity. Learning about the solar system is fun when planets tell the story them- selves. Dan Green’s Astronomy: Out of This World! contains fascinating facts and details along with cartoon illus- trations your child is sure to love. Worth quoting “Wondering is the seed of genius.” William Mocca Q: Why did the man water only half of his lawn? A: Because he heard there was a 50 per- cent chance of rain. Math at the grocery store info bits Just for fun Look at me! Help your youngster learn about the science of optics with this mealtime activity. Have her look at herself in a clean spoon. What happens if she looks in the bowl of the spoon? (She’s upside down.) What happens on the other side? (She’s right side up.) Next, have her bring her finger toward the spoon and watch what happens on each side. The bowl (the concave side) will magnify her finger, or make it look larger. The back (the convex side) will make her finger look smaller. Ask your child how scientists might use this information to make eyeglasses, cameras, or telescopes. Tip: She can remember which side is which by thinking of concave as “caves in.” or two boxes for $5? ($5 ÷ 2 = $2.50 per box, so you’ll save money buying two boxes and storing one for later.) Estimate the total. Ask your youngster to predict your total bill by keeping track of what you put in your cart. With each item, he should check the price and round it up or down to the nearest dol- lar. As you go, he can keep a running tally on paper, in his head, or on a calcu- lator. At checkout time, see how close he came.
  • 4. © 2011 Resources for Educators, a division of CCH Incorporated To provide busy parents with practical ways to promote their children’s math and science skills. Resources for Educators, a division of CCH Incorporated 128 N. Royal Avenue • Front Royal, VA 22630 540-636-4280 • rfecustomer@wolterskluwer.com www.rfeonline.com O u r P u r p o s e Page 2Intermediate Edition What’s the angle? Learning about angles is an important step in understanding geometry. Try these suggestions with your youngster: ●● Help her use her arms to demonstrate angles. For a right angle, she can stretch her left arm straight up and her right arm straight out to her side. An acute angle is smaller, so have her move her arms closer together. And an obtuse angle is larger than a right angle, so she should move her arms wider. ●● Next, see how many angles your child can find in the alpha- bet. Have her print all 26 uppercase letters on a large sheet of paper. With different-colored markers, have her mark right angles (one in “L,” for exam- ple), acute angles (three in “A”), and obtuse angles (two in “X”). ●● Together, look for angles in the real world. Right angles will be easiest to find—they’ll be in corners of rooms where one wall meets another, on window frames, or at the edge of a square sandbox. But your youngster will also be able to find angles that are acute (spokes in a bicycle wheel) and obtuse (a door that’s wide open). Suggest that she make a three-column chart (name of object, type of angle, sketch of the angle) to record her findings. How many times can your youngster fold a piece of paper in half? She will find out with this sur- prising activity.  Give her a piece of notebook paper, and ask her to predict how many times she can fold it in half. Then, have her test her prediction by folding the paper in half again and again until it won’t fold anymore. She’ll dis- cover she can’t fold it more than 6 times. Learning math words My son Kaiden struggles with vocabulary. And since he’s learning so many new math words this year, like circumference and integer, this problem was affecting his math work. I talked to Kaiden’s teacher, and she thought it would help to post the words where he could see them. She suggested that he write each word on an index card and illustrate it. Kaiden and I talked about what each word reminds him of. For instance, car tires help him remem- ber that circumference is the distance around a circle, so he drew a car with tires on his circumference card. We hung the cards on the refrigerator so he could see the words every day. Once he masters a word, we take it down and add it to a pile on the counter. By associating the math words with some- thing meaningful to him, he has been able to remember them more easily in class. And watching his stack of words grow seems to be giving him confidence. Save your breath Your child can inflate a balloon without using his breath. A chemical reaction will do the job for him! You’ll need: empty plastic soda bottle (20 fl. oz.), 1 –4 cup water, 1 tsp. baking soda, uninflated balloon, lemon juice Here’s how: Have your youngster add the water and baking soda to the bottle, close the cap, and swirl it around until the water is cloudy. Then, help him stretch out the balloon and place the opening over the top of the bottle, leaving a small space. He should very quickly add a squirt of lemon juice, seal the balloon com- pletely over the bottle, and shake lightly. What happens? The balloon inflates. Why? When you mix an acid (lemon juice) with a base (baking soda), they create carbon dioxide. The molecules spread out as the gas forms, pushing against the walls of the balloon and causing it to inflate. Paper folding Have her try again with different sizes and types of paper (tissue paper, paper towel, newspaper). No matter the size or kind of paper, she won’t be able to fold it more than 6, 7, or 8 times. Ask your child if she can figure out why. Hint: It has to do with doubling. The first time she folds the paper, she’ll have 2 layers. The next time, 4 layers, and so on…until 8 folds = 256 layers. The paper simply becomes too thick to fold again. parent to Parent SCIENCE LAB MATH corner
