#2 “11th Grade Math”CPW32Learning Intentions - Today, I am going to practice questions from similar College Readiness Standards that either:
1 More students got incorrect than correct.
2 More students put a specific wrong answer than the correct answer.
Success Criteria – Recognize some common mistakes, and don’t make them again!
11th Grade Math

1.
Consecutive integers are positive or negative counting numbers, or zero. Pick a couple of examples for m and n so that m < n, and quickly run through the answer choices.
3 < 4 -3 < -2 5 < 6 0 < 1
m is not always odd, and n is not always even, so A and B are wrong.4 – 3 = 1, so C is not correct.42 – 32 = 16 – 9 = 7 is odd, (-3)2 – (-2)2 = 9 – 4 = 5 is odd, as is 25 – 16 = 9, as is 0 – 1 = 1.
So, n2 – m2 is always odd.

First, apply the distributive property on the terms being subtracted.
Combine like terms, remembering there is a ‘1’ before the first a term.

First, apply the distributive property on both sides of the inequality.
Move the smaller x-term by subtracting 6x on both sides.
Add 35 to both sides.
Reverse the direction of the inequality as guided by the answer choices.

The area of a circle: A = π(radius)2
Since the diameter is 2, the radius is 1, and A = (3.14)(1) 2 = 3.14*1 = 3.1 square feet
ANSWER: A

To increase the diameter by 75%, multiply the current diameter by 1.75:
2 * 1.75 = 3.5 feet
ANSWER: D

All of the answer choices are linear equations in slope-intercept form, y = mt + b, where m is the slope, and b is the y-intercept. Also, this line uses t instead of the x that you may be more used to, but it does not matter.
Notice that the y-values increase by 5 and each t increases by 1, so the slope is 5/1 = 5. m = 5.Also recall that when t = 0, the corresponding y-value is the y-intercept of the line. When t = 0, y = 14, so b = 14.
The equation is y = 5t + 14. ANSWER: C

From point (2, 0), a vertex of the square can be any point 3 units away.
2 + 3 = 5, so (5, 0) is 3 units away, and COULD be a vertex on the square.
