Common Core Alg I, why so hard? It’s not for HS Seniors

Rigor?  Or graduation rate?  Hmmm.. this has been the debate for the Algebra Regents for many years.

If seniors need a Regents for graduation, the bar cannot be set too high, which has been the reason that Integrated Algebra Regents/Math A etc have not had high intensity.  BUT this year all the seniors were taking ye olde Integrated Algebra and most of the Common Core takers were 8th and 9th graders.  Wondering if this will get easier as this year’s freshmen approach their 2018 graduation date.

The June 2015 Common Core Algebra I Regents was more challenging than previous: read here although one poster wrote that her students did great with
the materials from below:  Just got a copy in the mail and will be reviewing it for Gen Ed, Sp Ed and ELLs.

The SAT essay will be optional and will be the last section.  It has a totally new feel and focuses on developing an argument that is powerful and persuasive.

OK SIT DOWN…SOME OF THE MATH DOES NOT ALLOW A CALCULATOR.  Since 1994, the SAT has allowed a calculator (disclosure: I am from BC: Before Calculators).  On the first read of the chapters, I do not see which problems allow the calculator and which do not…

The Additional Topics include very fancy shmancy Math like 3D geometry, Trig incl radians, and Complex Numbers

June 2015 Brain Teaser Solution

Q: Can you take the clock face below, and cut it into four pieces such that the numerals on each part add up to the same number?

A: The key is to turn the number XI upside down to a IX or:
turn the IX upside down to a XI
The numbers 1-12 add up to 78 which is not divisible by 4
Replace 11 with a 9 and the numbers now add up to 76 which is divisible by 4
and/or replace the 9 with an 11 and now the numbers add up to 80 which is also divisible by 4

Fortune Cookie: How Many Steps in a Mile?

A mile walked with a friend contains only a hundred steps

The experience of walking a mile with a friend can be so engaging that it may feel like only a hundred steps.
But mathematically speaking, those would be mighty BIG steps.
With 5280 feet per mile, 100 steps would make each step 52.8 feet: almost twice as long as the long jump record set in 1991 by Mike Powell.  Dividing 5280 feet by 29.375 feet/step is about 180 consecutive long jumps which would likely make anyone forget they were taking a walk with a friend (not to mention, we did not count the long runup to the long jump).

Surely this fortune from the Chinese restaurant: “A mile walked with a friend contains only a hundred steps” is using a metaphor.  Usually for most people, there are about 2000 steps in a mile.

So grab a friend and take a walk and feel only 5% of your steps!!
