Get the Math and Get the Points!! Jan 2016 CC Algebra I Regents #2

From the January 2016 Common Core Algebra I Regents

Jan 2016 Regents A1 2 Gas
This is a reading and noticing question with no TI-83/4 needed.
5 points are shown on this line but only 3 are easy to read: (4,15), (8,30) and (12,45)

Let’s check out each of the multiple choice options:
(1) When x = 10, is y = 35? (look carefully!)
(2) Look at the first point at a ‘crosshair’, (4,15)  divide $15 by 4, what do you get?
You can also use (30 divided by 8 or 45 divided by 12)
(3) When x = 2, is y = 5?  (look carefully!)
(4)  You can still drive if you did not buy gas (as long as there is gas in the tank!!)

Get the Math and Get the Points!! Jan 2016 CC Alg I #1 Notice x!!

As part of the Learn, Pass, Graduate series on the Regents exam, problems from the tests will be featured on a daily basis.

Jan 2016 Alg I Regents 1

Use your TI-84
Put the equation into Y=, then press graph!!

Read carefully — they want the       x     value of the minimum point
(not the y value which can be seen at (2,4).

This is easy ladies and gents — this is attention to detail.
2 points done!!

This is a great Do Now or exit slip…also easy to do at home :)

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

Screen3 Factoring

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.
