services, recreational areas, and housing. At home, the students create
a 3-D building or facility to place in the town. After the city has been
created, students provide a written mathematical description
of the building they designed. They can use geometric descriptions
using area, perimeter, volume, angles, measurements of distances, etc.
They can also explain the placement of the buildings,
modes of transportation and how they impact development, and other issues
cities grapple with as they develop.

Take black and white headshots of
each student, sized it to a quarter page with a box frame around it ...
then added a blank box beside it (the same size as the framed picture).
This would take up the top half of the page. Repeat the process with another
student's headshot and empty box below that first one. Then cut the page
in half giving each student their own headshot and blank box on the half-sheet.
The students then draw 1/2 - 1in. gridlines in pencil on both the headshot
and the empty box next to the headshot. They label the gridlines as 1,
2, 3, 4, 5, etc., going each direction. They try to duplicate their pictures

1)Pick your teams and chose one person to be dealer. (ex. 5 teams of 4
but teams do not have to be even.
2) Make target cards for each group. The target cards have a number from
-20 to +20 on them. One number per card.
3)Red cards are negative and black cards are positive. Aces=1, Jacks =
10, queens = 11, and kings = 12. All other cards are the value shown (2=2
4) Each player gets 2 cards from the dealer. The dealer also takes the
top card off the target card for the card the players are aiming for.
5) Players take turns trying to make their 2 cards equal the target card.
They may add or subtract to reach it. They must use both cards to reach
the target #. (This eliminates the player who has a red 7
and the target is -7) The first player to reach the target # wins a point.
The dealer must figure each "correct answer" out to ensure it
is correct. Cards are shuffled and play continues.

Staple an envelope for each type of piece next to the calendar, within
reach of students. Using additional calendar pieces, make a border
for your calendar that matches the chosen pattern. Each day, invite
a calendar helper to attach the appropriate piece to the calendar.
Using the border as a guide, students will begin to predict the pattern.
Use more complex patterns as children's skills improve. To teach
skip counting in multiplication, you can use red apples, green apples,
and apple baskets for you calendar pieces. Write the odd numbers
from 1 to 29 on red apples and the even numbers from 2 to 30 on green
apples. Write the multiples of 5 (5, 10, 15, 20. 25,30) on the six
apple baskets. Every day, ask a student to place the appropriate
odd or even apple on the calendar date. Every fifth day, a student
should place an apple basket on top of, but not completely covering, the
apple for that day. Explain that each basket represents a multiple
of five. If the preceding four apples were also in the basket, each
basket would contain five apples. Soon, students should be able
to skip-count by fives from basket to basket. You can also have
children skip-count by twos using the green apples. If you like,
add a colorful border of red apples, green apples, and apple baskets around
the calendar before the month begins in order to reinforce the pattern.
You can use the same calendar to teach multiplication equations.
Invite a student to write a multiplication equation directly on a green
apple or an apple basket. For example, 1x5=5 would appear on the
first basket, 2x5=10 on the second basket, and so on. Again,
you may wish to add a border showing the exact pattern that should appear
on the calendar. To reinforce your patterning, skip counting, or
multiplication lessons, you can also use individual 81/2" x 11"
blank calendars for students to mark on a daily basis, mimicking the same
pattern as that on the large classroom calendar. Direct children
to draw the patterns they see or to write the appropriate equation for
the day, such as those that appear on the apple baskets, on these individual
calendars. By having younger students practice patterns daily, you
can reinforce sequencing, skip counting, and multiplication skills in
an appealing, visual way.

Percentage lesson for middle school students:
Have students bring their favorite magazines from home, and provide a
few as well. Start the lesson by talking about fractions....1/2 of a page,
¼ of a page, etc. Working with a partner, students start at the
beginning of their magazine and record on a tally chart the number of
ads in the magazine. They then calculate the percentage of ads in their
magazine (89.5 pages of ads out of 120 pages). It's a real eye opener
for the students to learn that most of their magazines have more than
50% advertising. Record the percentages on a big chart paper and the students
select ten magazines to highlight in a bar graph........they must show
the amount of advertising in the various magazines in ascending or descending
order.......using a computer program such as Excel or Quattro Pro.
Place value lessons for fourth grade
Make 4 boxes (open on top)
labeled 1's, 10's, 100's, 1000's...give children each 12 pennies and have
them toss pennies into open boxes...then take out pennies in 1000's box
and count how many..(i.e. 6 pennies is 6000) put that on paper...then
take out pennies in 100's box and count how many (i.e. 4 pennies is 400)
put that on paper...so now 6400...and so on

Population Growth: http://www.k12science.org/curriculum/popgrowthproj/
This series of activities explores the mathematical and environmental
aspects of population growth. How fast is the population growing? Has
it always grown at this rate? Are the populations of different
countries growing differently? How can we predict the population in the
future? How will a growing population impact the environment? Using archived
census and demographic data as well as up-to-the-minute population estimates
from the U.S. Census Bureau, students will learn how to model
population growth and study the implications of a changing population.

Use the opportunity of spring to utilize
colored plastic eggs in math for several days. Using egg cartons cut to
make 'tens frames,' estimate, count, tally, sort, classify by color and
size (some eggs have smaller eggs inside), and calculate money (pennies,
nickels, and dimes). Extend the activity by using grocery sale ads from
newspapers to read how many cents items cost. Become smart shoppers
by determining which store has eggs on sale for the best price. Culminate
the egg unit with an egg hunt. Each child has to tally total number of
eggs found and they earn prizes from the treasure box based on accuracy.
Students are divided into two groups and each student
is given a card with a numerical value. There are various forms on the
careds (percents, decimals, fractions, etc.) It is a contest to see which
side of the room can line up in ascending order (smallest to greatest)
based on the numerical value of their card. They can not talk about it
within their group they can only use hand gestures or moving people around
in their own specific group. When one group is finished they yell time
and the other group has to freeze where they are. If the group that yelled
time first is wrong about the correct order the other group wins.
