The disney golf classic starts with 64 golfers. the golfers from pairs and each pair plays a match. the losers drop out and the winners of each pair then from new pairs and play again. then those winners form pairs and play. this continues until there is one winner. a. In how many matches must the winner play? b. How many matches are played by all the golfers, to determine the winner? Answer :6,63 Solution : 64 Play, then the 32 winners of those matches play, then the 16 winner of those matches play, then the 8 winners of those matches play, then the 4 winners of those matches play and finally the last two winners play. this is 6 rounds of golf, and the winner must play in all of those. since there are 63 losers, and each had to play a match to lose , there are 63 matches altogether. A number has 4 digits. No digits in the number are repeated. The digit in the tens place is three times the digit in the thousands place. The number is odd The sum of the digits in the number is 27. what is the number? Answer :3,897 Solution : There are several clues that make this guess-check-revise problem a little friendlier. since the sum of the four digits is 27, the average size of the digits must be fairly larger. however, the thousands digit has to be either a 1,2 or 3, while the corresponding tens digit is a 3,6, or 9. pick the 3 to begin the search, using 9 for the tens digit, and make the last digit a 7 since that's the largest odd digit not already used. this gives a sum of 27, as require , if 8 is the hundred digit. What is the mystery number x? . x has 3 digits. . The tens digit is half the hundreds digits . The number is odd. . The sum of the digits is 9. Answer :423 Expected Answer : "423" Solution : Guess-check-revise is one way to solve the problem. A starting hint is that since the sum of the digits is nine, their average value is 3 so they are all small number.

Problem Solving tasks can be combined with the other Core Skills Units: Communication, Numeracy, Information and Communication Technology, and working with Others. If you adopt this approach, records must be kept for each Unit. The approach used by Talent acdemy helps you to break the problems into mini-tasks that help to solve the problems effectively and efficiently. But the major skill set required is effective information assessment, we ensure to get students on board with the assessment to know their back falls and then work on it.
