1. SQUADS #2 “11 th Grade Math” CPW32 Learning Intentions - Today, I am going to practice questions from similar College Readiness Standards that either: 1More students got incorrect than correct. 2More students put a specific wrong answer than the correct answer. Success Criteria – Recognize some common mistakes, and don’t make them again!

2. 11 th Grade Math 1.1.

3. 1.1. 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 < -25 < 60 < 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. 4 2 – 3 2 = 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, n 2 – m 2 is always odd. ANSWER: D

4. 11 th Grade Math 2.2.

5. 2.2. First, apply the distributive property on the terms being subtracted. Combine like terms, remembering there is a ‘1’ before the first a term. ANSWER: E

6. 3.3. 11 th Grade Math

7. 3.3. 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. ANSWER: E

8. 4.4. 11 th Grade Math

9. 4.4. 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

10. 5.5. 11 th Grade Math

11. 5.5. To increase the diameter by 75%, multiply the current diameter by 1.75: 2 * 1.75 = 3.5 feet ANSWER: D

12. 11 th Grade Math 6.6.

13. 6.6. 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

14. 11 th Grade Math 7.7.

15. 7.7. Use the mid-point formula between two points: But the question just asks for the x-value, 5. ANSWER: C

16. 11 th Grade Math 8.8.

17. 8.8. 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. ANSWER: E
