* A Tricky Walk

    "You'll never believe what I saw at 5:00 this morning!" Carmen said to her friend Pat. "I was riding my bike to Townsville to deliver papers. I was all alone, when suddenly I saw this strange parade coming toward me.
     "It was the circus coming to town. First there were three elephants, with two men riding on each of them. Then there were four big white horses, and they each had two women riders. Last of all, there were two open trunks. One had three clowns juggling balls. The other had three more clowns doing handstands and cartwheels. You should have seen them!
    "Anyway, here's a question for you. How many people in all were on their way to Townsville at 5:00 this morning?"
    "Wait a minute!" said Pat. I can't remember everything you told me!"

Can you? How Many People were there?

* How Many Cookies?

    Karen and five friends were sitting in the kitchen when her Aunt Margo walked in. She pointed to a large plate on the counter.
     "Well!" she said. "I left an odd number of cookies on that plate. Now it's turned into a different odd number. Isn't that odd?"
     There were three cookies left.
     "It's my birthday, so we ate some," said Karen. "Is that odd?"
     "No," said Aunt Margo. "But the number was important. It's my birthday tomorrow. The number of cookies showed your age today and my age tomorrow."
     "How could it do that?" said Karen. "You're several times older than I am."
     "You'll see," said Aunt Margo. "Did anyone notice how many cookies there where?"
     The children all shook their heads no.
     "Then let's work it out," said Aunt Margo. "How many cookies did you have each?"
     Karen had 3. Maria, Lester, and Nikki each had 4. Kevin had 5. But Liza wasn't sure if she had 3 or 4.
     "Well never work it out," Karen sighed.
     "Sure you will," said Aunt Margo. "Just do a bit of odding - I mean adding - and you'll have the answer in a flash!"

Can you help them?

* Answer to "A Tricky Walk"

Is 20 your answer? If so you got some good calculation practice. But you didn't get the right answer!

The Question asks how many people were going to Townsville. The circus people were coming from Townsville. Only Carmen was going to Townsville. So the correst answer is 1.

* Answer to "How Many Cookies"

(Here is the answer to figuring it out. You might want to do this on paper.)

1. There were 3 cookies left. Five of the children knew exactly how many cookies they ate.
    a. Start by adding those six numbers.
    3 + 3 + 4 + 4 + 4 + 5 = _____
    b. Liza didn't know if she ate 3 or 4 cookies. Suppose she ate 3. Add that to the total in 1a:
     ____ + 3 = ____
    c. Now suppose she ate 4 and add that to the total in 1a:
     _____ + 4 = _____
    d. Aunt Margo said she put a odd number of cookies on the plate.
So the correct answer is ______.

2. Then Aunt Margo explained that the answer was her age tomorrow. But the digits added up to Karen's age today. (For instance, in the number 48, the digits are 4 and 8.)
    a. How old was Karen? ___
    b. Aunt Margo was several times older than Karen. How many times older? Keep multiplying Karen's age till you get the answer:
    ___ times 2 = ____
    ___ times 3 = ____
    ___ times 4 = ____
    ___ times 5 = ____
    c. So Aunt Margo was _____ older than Karen.
