Get the Math and Get the Points

Jan 2015 A1 Regents 3 Factoring

Every student should get 2 points from this type of question

Jan 2015 Regents #3:

This can be seen as a factoring question but there are many ways to do this question!!

  1. Checking the FOIL of all 4 answers to see which is equivalent to the original.
    and because First is 2x *x = 2x^2 Outer is -1*2x = -2x Inner is 3 *x which is 3x and 3 *-1 which is -3.  Combining the x terms of -2x and 3x creates a middle term of x so that the trinomial is 2x^2 +x – 3.

2. Using the logic values on the TI-83/4

In the photo above you can see that The answer is #4 because the truth value is “1” or TRUE.

3. Using Y1 and Y2
Students can also put the original equation into Y1 = 2x^2 + x – 3 and then try the other 4 equations into Y2.  They can check the graph to see if the two Y= are identical and/or they can check the Table to see if the xy points match.

The test is 3 hours so students should spend time checking their answers with multiple methods!

This 2 point question answered correctly can help students pass the Regents and understand the Math.

Vertical Line Test = Easy 2 Pts!! Jan 16 CC Alg I Regents #26

Do your students know this?  This is an easy 2 points

Word definition of a function: Every x must have just one unique y

Graphical definition of a function:
Does it pass the vertical line test?  If not, it is not a function.
Drawing a vertical line at x = 2, your vertical line will pass through both dots and therefore this is NOT a function.

Easy 2 points!!

How to Help Students Pass the CC Algebra I Regents

  1. content exposure: you have to see it to know it — use real Regents questions
  2. mixed practice: students benefit from a variety of topics
  3. independent work: can be entry/exit slip or checkpoint
  4. Kahoot or other online survey tools like PearDeck, Nearpod and PollEV
  5. Khan Academy or other practice software for skillsPlease click this link to see the Power Point from Get the Math and Get the Points
    presented at the New York City Math Project conference on May 21 at Lehman College

“You need to see it to know it.”
Regents Review: Get the Math and Get the Points

Students benefit from mixed Regents problems practice to improve their knowledge, confidence and performance on the new, more challenging Common Core Algebra I (and Geo) exams.  We will discuss building compare/contrast skills, increasing TI-83/4 knowhow and increasing persistence.   Come to this session to share teaching/learning strategies to enhance learning and help students graduate high school.

As of May 2016, there are 6 Algebra I Regents exams

March 2016 Brain Teaser Solution

Q:  What whole number can be added to 36, 300 and 596 so they all become perfect squares?

A: 925

36 + 925 = 961 (31^2)
300 + 925 = 12225 (35^2)
596 + 925 = 1521 (39^2)

Can try with a list of perfect squares subtract 36 and see if it is a perfect square.  If it is, now subtract 300 and check that answer.  If that one works, then try subtracting 596.
The lowest perfect square we can start with is 625 (25^2) as it is the first one larger than 596.
625 – 596 = 29 which is not a perfect square so we move to the next perfect square, 676 (26^2).
