**UNRAAVEL a Math Problem**Sure-Fire Steps to Becoming a Math Genius! UNRAAVEL Strategy presented by Larry I. Bell.**Sometimes it can be difficultto figure out what to do**whenyou are faced with a word problem. • Even Albert Einstein said: • “Do not worry about your difficulties in Mathematics. I can assure you mine are still greater.”**Period 1**U = Underlinethe question • Find the question and Underline it! The bungee chord stretched 150% of its original length during the first drop. If the chord is 160 feet in length, what distance did the chord stretch during the initial descent? The Saints scored three less than double the points scored by the Colts. If the Colts scored 17 points, how many points did the Saints score?**U = Underlinethe question**Find the question and Underline it! Period 1 - ANSWERS The bungee chord stretched 150% of its original length during the first drop. If the chord is 160 feet in length, what distance did the chord stretch during the initial descent? The Saints scored three less than double the points scored by the Colts. If the Colts scored 17 points, how many points did the Saints score?**Period 2**N = Now Predict • Do you think the answer will be larger or smaller? Do you think you will need to add, subtract, multiply, or divide? Are there any hints that you may need to estimate? The bungee chord stretched 150% of its original length during the first drop. If the chord is 160 feet in length, what distance did the chord stretch during the initial descent? The Saints scored three less than double the points scored by the Colts. If the Colts scored 17 points, how many points did the Saints score? Larger or smaller than 160? Add, subtract, multiply and/or divide? Larger or smaller than 17? Add, subtract, multiply and/or divide?**N = Now Predict**Do you think the answer will be larger or smaller? Do you think you will need to add, subtract, multiply, or divide? Are there any hints that you may need to estimate? Period 2 ANSWERS The bungee chord stretched 150% of its original length during the first drop. If the chord is 160 feet in length, what distance did the chord stretch during the initial descent? “of” indicates muliplication The Saints scored three less than double the points scored by the Colts. If the Colts scored 17 points, how many points did the Saints score? Larger or smaller than 160? Add, subtract, multiply and/or divide? Larger or smaller than 17? Add, subtract, multiply and/or divide?**Period 3**R = Read the Word Problem A = Are there important words? The bungee chord stretched 150% of its original length during the first drop. If the chord is 160 feet in length, what distance did the chord stretch during the initial descent? The Saints scored three less than double the points scored by the Colts. If the Colts scored 17 points, how many points did the Saints score?**R = Read the Word Problem A = Are there important words?**Period 3 The bungee chord stretched 150% of its original length during the first drop. If the chord is 160 feet in length, what distance did the chord stretch during the initial descent? The Saints scored three less than double the points scored by the Colts. If the Colts scored 17 points, how many points did the Saints score?**Period 4**What is your estimate of the stretched rope? What would you estimate for a score? V = Verify Your Answer. (Is it reasonable? Does it Make Sense?)A = Apply the Steps You Chose to Solve the Problem The bungee chord stretched 150% of its original length during the first drop. If the chord is 160 feet in length, what distance did the chord stretch during the initial descent? The Saints scored three less than double the points scored by the Colts. If the Colts scored 17 points, how many points did the Saints score?**V = Verify Your Answer. (Is it reasonable? Does it Make**Sense?)A = Apply the Steps You Chose to Solve the Problem Period 4 ANSWERS The bungee chord stretched 150% of its original length during the first drop. If the chord is 160 feet in length, what distance did the chord stretch during the initial descent? The Saints scored three less than double the points scored by the Colts. If the Colts scored 17 points, how many points did the Saints score? C = Chord Length S = Stretched Length S = 150% x C S = 1.5 x 160 S = 240 feet S = Saints’ score C = Colts’ score S = 2C – 3 for C = 17 S = 2(17) – 3 = 31 points**Period 5**E = Eliminate Wrong Answers. The Saints scored three less than double the points scored by the Colts. If the Colts scored 17 points, how many points did the Saints score? a. 17 b. 13 c. 37 d. 31 The bungee chord stretched 150% of its original length during the first drop. If the chord is 160 feet in length, what distance did the chord stretch during the initial descent? • 80 • 160 • 240 • 320**E = Eliminate Wrong Answers.**Period 5 ANSWERS The Saints scored three less than double the points scored by the Colts. If the Colts scored 17 points, how many points did the Saints score? a. 17 b. 13 c. 37 d. 31 The bungee chord stretched 150% of its original length during the first drop. If the chord is 160 feet in length, what distance did the chord stretch during the initial descent? • 80 • 160 • 240 • 320 Too low Too low Too low Too high Too low Too high**Period 6**L = Letthe Answer Stay or Rework the Problem The Saints scored three less than double the points scored by the Colts. If the Colts scored 17 points, how many points did the Saints score? a. 17 b. 13 c. 37 d. 31 Is the answer reasonable? Why or why not? The bungee chord stretched 150% of its original length during the first drop. If the chord is 160 feet in length, what distance did the chord stretch during the initial descent? • 80 • 160 • 240 • 320 • Is the answer reasonable? Why or why not?**L = Letthe Answer Stay or Rework the Problem**Period 6 ANSWERS The Saints scored three less than double the points scored by the Colts. If the Colts scored 17 points, how many points did the Saints score? a. 17 b. 13 c. 37 d. 31 Is the answer reasonable? Why or why not? The bungee chord stretched 150% of its original length during the first drop.
