1. TCAP

2. Some Reminders

3. Carefully read each question Read the entire question and all the answer choices Underline or circle key words….NOT DO the work… …draw pictures …write the problem DON’T just do it on a calculator DO all calculations twice (remember the calculator only does what you put in it!)

4. Positive – Negative Key Negative Numbers Press this key AFTER the number Then CHECK display

5. Tricky Expressions Evaluate –(-ab) 3 when a = -2 and b = -1 Insert values for varibles, then simplify a b -1 (-1 x (-2) x (-1)) 3 -1 ( 2 x (-1) ) 3 -1 (-2) 3 -1 x 8 -8 Follow order of operations

6. Percent Key Percent Key Only use this key to make a percent number a decimal to use for computation Percent Key This key DOES NOT change a decimal into a percent!!!!

7. Fraction Keys Mixed Numbers 1 2/3 1 unit 2 / 3 Fractions 2/3 2 / 3

8. Fraction Keys - Simplify Simplify and = Reduce proper fractions like: 2/4 14/28 25/1000 A b/c Changes improper fractions to mixed numbers 12/4 15/1 199/54

9. Lower extreme Upper extreme Median Lower Quartile Upper Quartile 10 20 30 40 50 60 70 80 90 100 25% Box and Whisker Plots Interquartile Range (75-35=40)

10. Exponents Square 2 2 = 4 12 2 = 144 3 2 = 9 Any exponent 5 3 Key: 5 y x 3 = 5 3 = 125

11. Know the difference!! X 2 X = -3 -3 x -3 = 9 -X 2 The opposite of x 2 X = -3 -3 x -3 = 9 opposite = -9

12. Square Roots Key 49 then Some numbers are not PERFECT SQUARE so the square root will not be a whole number = 4.89 Area = 49 each side is 7 7 x 7 = 49

13. Proportions Look for words like: Ratio Rate Similar 15’ flagpole 28’ shadow x tall tree__ 22” shadow = 15 x 22 = 28x 330 = 28x 330/28 = 28x/28 11.78 = x

14. Similar Triangles Find corresponding sides to write your proportion then solve!! x 5 12 15 = 15 x = 60 x = 4

15. Probability Number of Favorable Outcomes Number of Total Possible Outcomes

17. Relationships of values Directly Proportion Y x y = Kx linear Inversely Proportional xy = k and y = k/x nonlinear

18. Function Check Match type of relation with an equation. Directly Proportional A. y = x 2 + 3 Linear Equation B. y = x –1 Inversely ProportionalC. 24 = xy Nonlinear EquationD. y = -2x

19. Function Check Directly Proportional; Inversely Proportional Linear, Non-linear xy 212 318 424 xy 212 38 46 xy 25 36 47 xy 24 39 416 AB C D

20. Function Check Match type of relation with an equation. Directly Proportional; Inversely Proportional Linear, Non-linear AB C D Not a straight lineStraight line and passes through (0,0) Straight line but doesn’t pass through (0,0) Not a straight line one value increases while the other decreases

21. YXYX

22. Just Remember It’s not confusing!! You know this. Just make sense of the information given!
