Week #18 The 12 Days of Christmas
It is very simple this week. Find out the cost of all the items in the “12 Days of Christmas” song.
List the cost for each gift item separately and then as its own group.
Write it up in a table format using the headings;
Day of Christmas
Gift
Cost of Gift
Total cost of Gift(s)
Final Total of all Gifts
Where you surprised by the total? Would there be a difference if you ordered the gifts on the
Internet? How much, if any, would that be? Is it more or less? Can you think of any reasons not to
use the Internet to buy gifts?

to his paper chain every day. Barb's chain has 9 links right now, and Chuck's
chain has 3 links right now. If they keep adding links at the same rate, how
many days will it be before Chuck's chain has exactly TWICE as many links as
Barb's chain?

Week 14 Standing in Line
Estimation and measurement of time are basic skills for all. Businesses such
as banks, fast-food restaurants, ski areas, and airports need efficient ways
to minimize time spent waiting in line.
Part 1
You are standing in line to see you favorite movie or band. You are wondering
how long you are going to have to stand in line before you get to the ticket
window.
There is a person in charge of handing out line numbers and you find out that
you are the 300th person in line. How long do you think you would have to
wait in line until you will be able to purchase your tickets?
Hint: The estimated average wait time is 30 seconds. Use this estimate to
find the amount of time you will have to wait in line.
Part 2
When you or your parents go to a restaurant, grocery store, or somewhere
waiting in a line is required, keep track of the amount of time it takes to
get through the line. Write down the number of people in front of you and the
time it took get through the line. Calculate the average time you had to wait
in line. If possible, find out if the express line really is “express”. Also,
make a list of the factors that would make a line move slower or faster.

Week 10 The shepherd and his sheep
A shepherd with 6 sheep had 13 sections of fence which were arranged
into 6 pens of identical size and shape (congruent). The arrangement is
represented with 13 toothpicks shown on the board in your classroom. (Sorry,
I cannot create the picture for the teacher web page.)
One evening, someone stole one of the fence sections leaving only 12. After
thinking long and hard, the shepherd rearranged the 12 sections to form 6
pens of identical size and shape for the sheep.
Use 12 toothpicks to show how the shepherd made the six pens. This can be
done without any overlapping or cutting of any toothpicks. Glue or tape your
solution onto a piece of paper.
