(P. Bear is the main character in the story. He is a Polar Bear.) |
|
In the story, P. Bear (a Polar Bear) invites his friends for a New Year's Party. At each clock hour guests arrive. The guests are:
1 whale at 1 o'clock
2 horses at 2 o'clock
3 dairy cows at 3 o'clock
4 zebras at 4 o'clock
5 panda bears at 5 o'clock
6 mountain goats at 6 o'clock
7 snow leopards at 7 o'clock
8 Dalmatian dogs at 8 o'clock
9 skunks at 9 o'clock
10 Canada geese at 10 o'clock
11 cats at 11 o'clock
and 12 penguins at 12 o'clock.
Question: Can you guess what all the guests had in common?
Answer: ".etihw dna kcalb erew stseug eht llA"
At the end of the story, after all the guests had arrived,
the words in the book say,
" How many guests came to the party?"
We did math lessons to find the answer:
1. First, we wrote the names and numbers of the guests
in a column on the classroom whiteboard.
2. Second, we made estimates (our best guesses) of how many guests came to P. Bear's party in all.
Here are the estimates that our class made:
12, 29, 42, 43, 55, 58, 60, 67, 73, 78, 81
You can do
our math lesson to find the answer.
When you see a red sentence with a star *, that is a step for you to do in the P. Bear Math lesson.
* Make a list of the guests and make an estimate of how many guests came in all. Write your estimation on a piece of paper.
After
we made our estimates, we used different math tools to help us find
out exactly how many guests came to the party.

kangaroo counters toy
plastic animals and
bean counters.
Working in small groups with different math tools, we lined up the "guests" that came to the party at each hour of the clock. We lined them up in rows.

* Choose some kind of math tool and line up the guests in rows (in a triangle) starting with one math tool for 1 whale in the 1st row, then two math tools for 2 horses in the 2nd row, three math tools for 3 dairy cows in the 3rd row...until you have all the guests in your triangle of rows.
After
we lined up the "guests"
using our math tools, we regrouped our
"guests"
into groups of ten to help us count how many came to P. Bear's
party.
Sorting kangaroos into groups of ten.
Sorting
animals into groups of tens with some leftover.
*
Now sort
your math tools into groups of ten. You will have some left over that
won't make a complete group of ten.
When
we had our math tools in groups of tens, we counted by tens and then
ones to find out how many guests
came to the party.
* Count your math tools by tens and ones to get the answer. Write your answer on a piece of paper. Send your answer to us at our classroom email address

We will send you an email reply
to tell you if your answer was the same as ours.
Happy 1999!
