August 2015 Brain Teaser Solution

Q: You have 8 batteries but only 4 of them work and 2 are needed to power a flashlight.  What is the fewest number of pairs you need to test to guarantee you can get the flashlight on?
A: 7. If you break the batteries into 3 groups: Two groups of 3 and one group of 2. By doing this you guarantee that one of the groups has 2 working batteries. Both of the groups of 3 have 3 possible combinations of 2 batteries and the group of 2 only has 1 combination. So, 3 + 3 + 1 = 7 tries at most to find two working batteries.

SAT Weeks 3 and 4: My book looks loved

1438796197048My book is looking loved!  Check out the dog ear on the upper right hand corner of the blue College Board SAT book!

During weeks 3 and 4, I took the 4 non essay sections of each of the 4 exams in the SAT book.
This content is much more challenging than the old SAT.   I am not sure why the College Board is making the exam harder than it was.  It seems like many students will jump to the ACT.
Next steps:
Work on each of the 4 essays
Go through the Ivy Global SAT book ( arriving this week)
Get familiar with the Khan Academy offerings for SAT prep

Read This Carefully!! The Complexity of SAT Reading Passages

Read this carefully regarding the new SAT Reading Test:

“All Reading Test passages are selected from previously published works and represent some of the best writing and thinking in the fields of classic and contemporary U.S. and world literature, history/social studies, and science. The passages on the Reading Test vary in complexity, ranging from texts like those found in challenging courses in grades nine and 10 to texts comparable to those assigned in typical college-level, credit-bearing courses. The test asks students to base their answers on what is stated or implied in the passages and any accompanying supplementary material, such as informational graphics.”

Each of the 4 exams in the new SAT book has 5 reading passages which can be accessed here: https://collegereadiness.collegeboard.org/pdf/sat-practice-test-1.pdf

here are links to the sources for Test #1
excerpt from the novel The Strangeness of Beauty by Lydia Minatoya
from the Journal of Experimental Social Psychology “Money Can’t Buy Love”
from Nature: Francis Crick and James Watson on DNA  available for $5
Three Guineas by Virginia Woolf see page 53
Both from New Scientist: Passage 1:Space Mining: The Next Gold Rush?  Passage 2:Taming the Final Frontier

On the first pass on July 16th, I got 39/52.  Perhaps I am rusty at Reading Comp but these felt much more challenging than the old SAT Reading Comp.  Stay tuned for the next blog post on Writing and Language.

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.
http://www.nysedregents.org/algebraone/615/algone62015-exam.pdf

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 http://mathforum.org/kb/thread.jspa?threadID=2716734 although one poster wrote that her students did great with
the materials from http://www.emathinstruction.com below:  Just got a copy in the mail and will be reviewing it for Gen Ed, Sp Ed and ELLs.

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

and will be starting Part 4: Four Official Practice Tests with Answer Explanations
