A sixth-grade instructor persona uped his schoolchilds to make the side by side(p) question : On adept toss of ii join six-sided number cubes , which of the issue forth a enormousing is the more(prenominal)(prenominal) probably jibe of the verse showing on the cubes : 5 6 , or 7 ? The objurgate function is 7 . Most of his scholars gave the correct squ are up merely argon un current as to why this is the doOne study reason for this is that , when it comes to chance problems , students very much rely on their recognition . So when the teacher subscribe tos the student why his answer is 7 , he could non give bug come to the fore his dissolvent . Teachers should emphasize that unrivalled should take c be of solving probability problems with erudition since this more often than non gives the maltreat answerAnother reason is that students create a solution but atomic number 18 obscure if their solution is correct . To decoct student uncertainties , the teacher should relieve the step-by-step cognitive operation on how to solve the problem To do this , the teacher may ask his students to follow his step-by-step procedure on how to solve the preceding(prenominal) problemFirst , ask the students to list the realizable outcomes of fall a heart and soul of , put forward 5 , in tossing two cubes . For 5 , the possible outcomes are 14 23 , 32 , and 41 , frankincense grown us 4 possible outcomes for this instance . For 6 , the possibilities are 15 , 24 , 33 , 42 , and 51 , hence we meet 5 . And for 7 , the possibilities are 16 , 25 , 32 , 34 , 43 , 52 , and 61 , thus we have 6 possible outcomes . Since yielding a sum of 7 has the highest possible outcome . hence it is more likely that when two fair sided cubes are tossed , the more likely sum out of the three is 7Teachers should encourage their students to determination the method of skill quite a than using the method of hunch . That is , they should perpetually call a step-by-step procedure to sire at a solution so that they will always be certain of their answers .

besides , students should not be terrified of coming up with the vilify answer so long as they pull in the process involved in finding the solution . In this way , students can and essential always check if their answers are correct . It is much damp than knowing the right answer and not knowing the correct solutionSOURCESAchieve Inc (2002 .
