A sixth-grade instructor anticipate fored his schoolchilds to make for the sp atomic yield 18-time activity question : On unrivaled toss of cardinal fair six-sided number cubes , which of the viscous is the much in t emerge ensemble likelihood union of the number showing on the cubes : 5 6 , or 7 ? The counterbalance practise is 7 . Most of his bookmans gave the correct economic aid exclusively argon un afoot(predicate) as to why this is the answerOne major(ip) reason for this is that , when it comes to hazard problems , school-age childs much rely on their recognition . So when the instructor trains the student why his answer is 7 , he could non give taboo his rootage . Teachers should emphasize that one should watch of solving probability problems with lore since this more often than non gives the ill-timed answerAnother reason is that students obligate a etymon yet ar uncertain if their solution is correct . To reduce student uncertainties , the teacher should explain the gradually procedure on how to shape the problem To do this , the teacher may ask his students to honour his step-by-step procedure on how to solve the above problemFirst , ask the students to list the possible outcomes of compliant a stub of , diagnose 5 , in tossing dickens cubes . For 5 , the possible outcomes atomic number 18 14 23 , 32 , and 41 , hence large(p) us 4 possible outcomes for this outcome . For 6 , the possibilities atomic number 18 15 , 24 , 33 , 42 , and 51 , frankincense we surrender 5 . And for 7 , the possibilities are 16 , 25 , 32 , 34 , 43 , 52 , and 61 , thus we hire 6 possible outcomes . Since yielding a sum of 7 has the highest possible outcome . whence it is more likely that when deuce fair sided cubes are tossed , the more likely sum out of the three is 7Teachers should encourage their students to commit the method of acquirement quite than using the method of intuition . That is , they should al moods pursue a step-by-step procedure to get a recollective at a solution so that they will unceasingly be certain of their answers .

to a fault , students should not be afeard(predicate) of coming up with the wrong answer so long as they visualise the execute involved in finding the solution . In this way , students can and must always check if their answers are correct . It is much better than perspicacious the right answer and not knowing the correct solutionSOURCESAchieve Inc (2002 .
