## Holiday Math Problems!!

Ellen and Henry Captivated by Santa

While all of you are bored from sleeping in, sipping eggnog, and munching on fruitcake, try a few of these holiday math problems courtesy of MathCounts.

Ariel and Thomas are playing the Dreidel game.  In their version of the game players take turns spinning the dreidel and take various actions based on which symbol is face up when the dreidel stops spinning.  The four actions the spinner can take are (1) put two tokens in the pot, (2) take half of the tokens from the pot, (3) take all of the tokens from the pot (and all other players each deposit one token into the pot), or (4) take no action and the next player spins. Before they begin, the total number of tokens is divided evenly between them.  To start the game Ariel and Thomas each deposit one of their tokens into the pot.  Ariel spins the dreidel first and must place two of her tokens in the pot.  For Thomas’ first spin he does nothing.  In the second round Ariel spins and must take half the tokens from the pot, while Thomas’ spin then results in his placing two tokens in the pot.  During the third round Ariel does nothing after her spin.  When Thomas spins he takes all the tokens from the pot which is equal to 2/5 of the total number of tokens.  How many total tokens does Thomas have after taking these tokens?

Every year on the first day of Christmas my true love gives me one gift, a partridge in a pear tree. On the second day of Christmas my true love gives me a total of three gifts, two turtle doves and a partridge in a pear tree.  This will go on until the twelfth day of Christmas when my true love gives me a total of 78 gifts given: 12 lords a-leaping, 11 ladies dancing, 10 pipers piping, 9 drummers drumming, 8 maids a-milking, 7 swans a-swimming, 6 geese a-laying, 5 golden rings, 4 calling birds, 3 French hens, 2 turtle doves, and a partridge in a pear tree. Today I’m at home “alone” with the gifts from my true love.  Assuming each person, and each bird, has two legs what day of Christmas is it if there are now 200 legs in my home (not including mine)?

Each year Desmond and his family take part in the cultural celebration of Kwanzaa.  The observance centers around the seven principles of Kwanzaa: Umoja, Kujichagulia, Ujima, Ujamaa, Nia, Kuumba and Imani.  Suppose Desmond writes each of the five letters of the seventh principle, Imani (Swahili for Faith) on its own index card.  If Desmond places the five cards in a bag and randomly chooses three cards, what is the probability that he chooses the three letters of the fifth principle, Nia (Swahili for Purpose)? Express your answer as a common fraction.

## Problem of the week! Mwahahahaha!

We had a great MathCounts problem this week that caused much discussion and consternation.  The problem was

“At how many minutes after noon do the hour hand and minute hand of an analog clock first meet again?  Express your answer to the nearest whole number.”

This led to a discussion in one of my math classes as to what the exact time the two hands meet.  This is a much more challenging problem.  Have fun!

## Roaring Springs

The trip to roaring springs was fantastic.  Everyone caught fish.  The extra days of casting practice with Mary Ann Dozer and the fantastic Echo rods, reels, and lines donated by Echo and Wes Campbell at BackCountry Fly Shop made all the difference in the world.  Thank you Wes, Mary Ann, and Echo.  Thank you also Rick Hagan at the Roaring Springs Trout  Ranch for making the wonderful ranch available at a reasonable costs.

The fly fishing class field trip is tentatively planned for October 12 (teacher inservice day).  We are planning to go to Roaring Springs again.  If you are interested in chaperoning, please contact me by commenting below, and make sure you have all the insurance/background check stuff into the office.  The student and adult chaperone cost will be about \$40 each.

## Dead Man’s Hand – Math Problem of the Week

Hey math students.  Periodically I will give you a cool math problem to solve.  Turn in your worked out solution for a point of extra credit.  (Must be turned in the week it was posted.) This first question caught my attention because of the cool skull/spinal cord graphics and because it is poker related.

Q:  What is the probability of getting dealt a “dead man’s hand” in a five card poker game?

The “DEAD MANS HAND” is the nickname given to two pairs,
the black aces and the black eights.
In 1876 the gunfighter WILD BILL HICKOK was murdered
in a saloon in Deadwood, Black Hills, Dakota while playing poker.
Legend has it that these were the cards he was holding when he was shot.
Nobody is sure what the fifth card was, or even if it had been dealt.

## Welcome back Ashbrook middle school students

It’s great to be back at Ashbrook getting ready for the new school year.  So many cool new things are in store for this year, but first,  I have to announce the arrival of our gorgeous new mini-calaca Ellen Eliza, born on August 18th.

Little “Len” at one week.

Henry is a crazy handful but as adorable as ever.

Keep checking this site.  I plan on adding content as the year progresses and using this for communicating with my students through the school year.
