Test-Taking Strategies/MS Version: 6 th grade

Transcription

1 plaer wins not merel because he has more knowledge, or desire, or preparation, or luck, but because he knows his game inside out. Good test takers, like good game plaers, don t even blink when the find themselves in uncharted territor. On the contrar, the revel in the knowledge that, though others ma stumble, the will find a wa, because the are armed with a method and with the confidence that method instills. Michael onner Step : Know our opponent opic acronm meaning length of time/tpes of questions R scoring Multiple hoice onstructed Response Full redit Partial redit Minimal redit No redit Your response addresses all parts of the questions clearl and correctl. You use and label the proper math terms in our answer. Your response shows all the steps ou took to solve the problem. Your response addresses most parts of the question correctl. Your response does not show all of our work or does not completel explain the steps ou took to solve the problem. Your response addresses onl one part of the question correctl and explains the steps ou took to solve that one part. n answering the remaining parts of the question, our response is incomplete or incorrect. Your response does not show all of our work or does not explain all the steps ou took to solve the problem. Your response is incorrect. use of calculators degree of difficult formulas given on test penalt for wrong answers? Southern Nevada Regional page of 0

3 Strateg : Process of Elimination est writers often construct their incorrect answers not to be reasonable but to anticipate common errors that are made b students in a hurr. Watch out for multiple step problems! Example : Barne bus a coat from a catalog, priced at $0. here is also an $8 shipping charge and a $ handling fee. f there were a 0% sales tax on the entire amount, what would be the total cost of buing the coat? $5 B $50 $60 $65 Spinner Example B: f the spinner was spun 00 times, which graph would indicate the correct theoretical probabilit of landing on each of the three colors? White Blue Blue Red Red 60 B Red Blue White Red Blue White Red Blue White Red Blue White Example : Sasha surveed 00 students to determine their favorite sport. he results are listed in the table. Which circle graph best represents the information in the table? Favorite Sport Number of Votes Football 00 Baseball 5 Basketball 50 Soccer 5 B Soccer Soccer Soccer Football Baseball Baseball Football Football Basketball Basketball Baseball Basketball Soccer Baseball Football Basketball Southern Nevada Regional page of 0

4 Strateg : Measure t When ou are at a loss of how to do a geometr calculation, especiall when ou see diagrams, make a measure (phsical or mental) and compare it against the answers given. Example : f the perimeter of triangle B is m, find the length of side B. B 0 m m m m B m Example B: he diameter of a circular mirror is 0 inches (in), as shown below. Bonnie wraps a piece of ribbon once around the outer edge of the mirror. What is the length of the ribbon? (Use π =. ) B 5.7 in. in 6.8 in 78.5 in 0 in Example : ngle P is shown. Which angle is supplementar to angle P? 5º B 5º 55º 5º Southern Nevada Regional page of 0

5 Strateg : Backsolve When in doubt about selecting from two or more answer choices, tr each answer out to see which one works. Start from one of the middle choices and work out (that wa if it doesn t work, ou can tell whether to go up or down). n other words, work backwards. Example : he ratio of the length to width of a box is to. om is going to draw a box using the same ratio. What would be the length of om s box if the width is inches (in)? B 5 in 7 in 9 in in Example B: Paul used a rule to create the pattern shown in the chart below. n m Which expression below would represent Paul s rule? n + B n n + 7 n 7 Example : f n + n + n = 60, what is the value of n? 0 B Southern Nevada Regional page 5 of 0

6 Strateg : Plug-n Numbers at Random Make an attempt at trial solutions b assigning an arbitrar value to each unknown term. t is usuall advisable not to use 0,, or as the often produce unique situations. Example : Francine is 5 inches taller than her brother Harold. f the letter h represents Harold s height, which expression could be used to determine Francine s height? h + 5 B h 5 h 5 h 5 Example B: Which of the following statements is alwas true for all real numbers a and b? a b= b a B a b= b a a b = b a a = b Example : he length of a rectangle is more than its width. f L represents the length, what is an expression for the width? L + B L L L Southern Nevada Regional page 6 of 0

7 Strateg 5: Plug-n Plot t When ou are unsure how a graph would look after looking at the equation or written scenario, make an attempt b assigning our own values for points and plot them! Example : Gloria created a number pattern using the rule = x+. he table shows some numbers in the pattern. Which of the following graphs could Gloria use to represent the rule? B x Example B: Joe creates a number pattern b using the following rule: take a number and subtract three from it. he table shows some numbers in the pattern. x Which of the following graphs would represent Joe s rule? 5 B Example : Water is poured into an empt clinder at a constant rate. he table shows ou some of the data. Which graph models the level of the water in the clinder over time? time depth B depth depth depth depth time time time time Southern Nevada Regional page 7 of 0

8 Please see our instructor regarding this strateg! Strateg 6: he Wild Guess ame t! Strateg 7: onstructed-response tems hese are the essa questions on the test write down all ou know about solving the problem. Show all our work! nclude pictures, algebraic expressions, equations anthing that will help the test grader understand our work. Support our answer b explaining our work with words. You ma want to create columns, one for work and one for explanation. Example : sandwich shop offers a selection of bread, meat, and cheese to choose from to make a sandwich. hese choices are shown in the chart below. Bread Meat heese Wheat hicken merican White Beef Swiss reate a list or a diagram that shows all the possible combinations of sandwiches that could be ordered. B Based on our list or diagram, what is the probabilit that someone will choose a chicken-merican cheese sandwich on wheat bread? Show our work. Example : Stud the diagrams of the triangle and rhombus. Knowing that the triangle contains 80º, what is the sum of the interior angles of a rhombus? Explain our answer (ou ma use a diagram). B nother student found the answer b finding the product of (80). Explain wh this is correct or incorrect. Southern Nevada Regional page 8 of 0
