Happy Fourth of July

Today, we celebrate the birth of the greatest nation, The United States Of American.  Our leaders in 1776 declared independence from the Kingdom Of Great Britain – thus the birth of America.  236 years of freedom and still going strong.    Our freedom symbol, recognized world wide is our Flag, the Flag of the United States Of America.  Display her proudly and properly. Let our heart and mind know that our men and women in the armed forces protect our country and our flag against all her enemies, whether they be found within or without the boundaries of their republic. May our country, in dealing with other countries – May she always be right; but it is still our country, right or wrong.  ~By Jim McShane

Curriculum Resources:
Rhoda Cratty describes books and websites from this dramatic and turbulent period in our history (1775-1776).  These resources and Cratty’s post on the Declaration of Independence, will, according to Cratty help students “begin to understand the history behind the fireworks.” Click here for the resource list.

Happy Fourth of July!

Happy Pi Day and Einstein Birthday day!

pi

Today is March 14, which corresponds to the first three digits of Pi. Because pi is 3.14159….some schools hold their celebrations until 1:59.

Pi is called an irrational number; it has an infinite number of digits:  3.1415926535 8979323846 2643383279 5028841971 6939937510 5820974944 5923078164 0628620899 8628034825 3421170679…First 100 digits of Pi

Pi is the ratio of any circle’s circumference to its diameter.  In other words Pi is the number you get when you divide the circumference of a circle (the distance around the circle) by its diameter (the distance across). It is typically written as 3.14.

March 14th also happens to be the birth date of Albert Einstein—which makes it a double math celebration. You can  watch NOVA‘s “Einstein Revealed,” which exposes the hidden life of Albert Einstein and traces the birth of his groundbreaking ideas. See it at: http://to.pbs.org/15OBsMm

A brief history of Pi: by Rhonda Cratty

  • Ancient Babylonians determined the area of a circle by taking 3 times the square of its radius, which gave the value of pi, 4,000 years ago.  One Babylonian tablet found, revealed a value of 3.125 for pi, which is a closer estimate.
  • In 1706, William Jones began using The Greek letter π.
  • Euler made the symbol popular in 1737.
  • 1761, Lambert proved that Pi was irrational; it cannot be written as a ratio of integer numbers.
  • In 1882, Lindeman proved that Pi was transcendental, that is, that Pi is not the root of any algebraic equation with rational coefficients. This discovery proved that you cannot “square a circle”, which was a problem that occupied many mathematicians up to that time.

My Favorite Activity to celebrate Pi Day:

life of pi***Read an excerpt from the book Life of Pi. I like to read Chapter 56 on fear since math is often fearful for students (and others of us!). Here is a post which spotlights just Chapter 56.

Other Activities to celebrate Pi day: by Rhonda Cratty

  • Who can memorize and recite Pi to the most digits without a mistake!
  • Read a variety of stories involving the use of measuring circles.
  • Read about ancient Egypt and Archimedes
  • Measure the circumference, diameter and radius of objects around the house.
  • Only eat circular food.
  • Create your own Pi T shirts using Fabric Paint or Fabric Markers
  • Pi Bracelets, with each bead color representing a number
  • Make a pizza measuring the circumference, diameter and radius.
  • For dessert, of course, you must have pie!

Literacy Week~week of January 14

An excerpt of a blog post by Rhonda Cratty:

literacy weekThe week of January 14th 2013 marks the Fifth Annual Celebrate Literacy Week, in Florida. Florida’s Department of Education, administrators, teachers, schools, students, and parents are participating in the “Take the Lead and Read” campaign.
Good for Florida, starting 2013 with the focus on Literacy; perhaps we all should spend the year focusing on our personal Literacy development.
We hear the word Literacy within schools each day. What does the word mean and why should it be interlaced within all our daily lives.
The very word, Literacy, is the ability to read for knowledge-to understand what you read, write coherently-so others may understand what you write, and think critically about the written word-to be able to use the information you gain. To be able to think critically about what is written, or said, is important throughout our lives. We need to continue to hone not just our children’s but our reflective skills and improve critical thinking skills through careful analysis, reasoned inference and thoughtful evaluation of what we read and hear each day from our culture and ideas brought to us through the written and spoken word…
