Dear Parents or Guardians,
Once again on your children's report cards I showed the current indication regarding the best math class for them next year. The Q2 indication was based on a weighted average of tests (60% weight) and quizzes (40% weight). Please contact me if you have any questions.
The NJSLA will begin on May 4. The Algebra 1 exam will have two units each 90 minutes long. The Math 8 exam will have three units each 60 minutes long.

Carl Sandburg's biography of Abraham Lincoln (born February 12, 1809) recounts how, when a young lawyer trying to sharpen his reasoning skills, the largely unschooled Lincoln "...bought the Elements of Euclid, a book twenty-three centuries old...[It] went into his carpetbag as he went out on the circuit. At night...he read Euclid by the light of a candle after others had dropped off to sleep." This story made it into the 2012 movie Lincoln. Daniel Day-Lewis won his third Academy Award for best actor for his performance.

Do you know why February 15th is known as Decimal Day?
"The book of nature is written in the language of mathematics."

Wind Chill is a measure of the chilling effect experienced when strong winds are combined with cold temperatures. The wind chill temperature is what the temperature "feels like" to people and animals during cold weather. It does not apply to plants or vegetation because they are not warm-blooded. We all know that a windy winter day can feel much colder than a calm one, although the air temperature may be exactly the same. The term "wind chill" was first coined back in 1939 and a formula to calculate it was published in 1945. In 2001, the U.S. and Canadian Weather Services replaced that formula with the one shown below. The new formula to calculate wind chill (WC) uses many algebra concepts.

WC = 35.74 + 0.6215T - 35.75V0.16 + 0.4275TV0.16

where T = temperature (°F) and V = wind speed (MPH). For example, if it is 30°F and the wind is 20MPH, it feels like 17°F.

keep going."
