Cartographer’s Challenge

Students in the fifth grade are taking on the challenge of both explorer and mapmaker.  Time will be given in my classroom to work on this project; however, students might have to do some work at home…depending on what they get done in class.  This project is due on September 30, 2009.

Fifth Grade annual “Boo”graphies”

All 5th graders will be working on a “Boo”graphy” (Biography) the month of October. The final activity for this will be on October 31, 2009.  Watch for more information coming soon.

To get a head start…Students will need to select and read a book about a famous person from history.  I am encouraging students to look for some one different from Abe Lincoln and Babe Ruth!  There are always lots that we see year after year.  There are so many interesting people from the past.  Also the focus will be on what that person did to stand out in history.  A free-standing poster (other props are optional) will need to be about that person, an oral presentation in costume will be presented to parents, families and Arcadia students the morning of October 31st

Display at Yoke’s

Our class, along with Mrs. Dott’s class have a display up at Yoke’s.  It is entitled “Are you smarter than a 5th grader in math?”  I hope you stop by and participate in the challenge.  It will be up until September 30th.

Arcadia Trivia

Mrs. Palanio Trivia:  Mrs. Palanio has taught the following subjects/grades in the DeerPark SD…4th grade, 3rd grade, 1st grade, Remedial math for 2nd and 3rd graders, HS English, TOSA as district K-12 curriculum coordinator, and now 5th grade.  She has also taught in the old Deer Park Elementary, Deer Park High School and Arcadia.  In addition, Mrs. Palanio has taught in the Granite SD, near Salt Lake City, while her husband played professional hockey there, and in the Spokane School District.  Deer Park is a great district to both work and live.

ARCADIA Trivia:  Did you know that Arcadia Elementary is named after the Arcadia Apple Orchard, which was the world’s largest apple orchard?  The orchard was irrigated with water coming from Loon and Deer Lakes.  Because of the large amount of water used, these two lakes were nearly drained dry!  The orchard was only in operation for about 20 years.  Want more information…read the sign on the north-west corner of the Arcadia playground.

 

Open House for 5th Grade

Open House for 4th and 5th grade will be on September 17, 2009.  Watch for more information this week.  Fifth Grade open house in from 6:30 to 7:00.  I hope to see you there to learn about fifth grade.

Let’s have fun with math! So what is a palindrome?

A palindrome is a word, phrase, sentence or number that can be read from left to right or right to left and are exactly the same.  Some examples of palindromes are: mom, noon, race car, 1991 and 2002. 

So here comes part of the fun.  How many different palindromes are found on a digital clock (in a 12 hour time frame)?  Please no “military time” although that might add some interest to the problem!  Most of the students figured this out as 4th graders.  HINT: Be sure to look for patterns and use an organized list.

Number Sense:  Ask your child what he or she knows about this number: 1,005.  Ask your child to explain how they know.  Be careful…the word digital root or composite/prime number might surface!

What might that number represent in the real world.  Examples: Approximate distance to Disneyland from Deer Park, the population of a middle size town, …

 

Digital Root in math helps us multiply and divide.

Math:

Students have been learning to find the digital root of numbers to help them know if a number is a multiple of a certain factor.  (The reverse is this is divisibility rules.)  

What is a digital root you ask?  To find the digital root of a number you simply add the digits of that number together until you find its single “digit root”.  For example, 27 becomes 2 + 7 = 9.  Nine is the digital root of 27.  The digital root of 39 is 3 + 9 = 12, 1 + 2 = 3, so the digital root of 39 is three.  So how does this help us in math you ask.  We have found that all multiples of three have a digital root of 3, 6 or 9.  So is 423 a multiple of 3?  Find the digital root to find out.  (This also will help you know if 423 can be divided equally by 3.) 

There are some other interesting patterns that emerge when finding the digital root of other numbers.  For instance take the first 10 multiples of 9 ( 9, 18, 27, …) and find the digital root.  What do you notice?  Can that help you when learning the basic facts for nine?  How about a general rule for the multiples of nine?  What about when dividing by nine?  Ask your child to show you some of the other patterns they found when they plotted their digital roots on a 9-point circle.
