Mathematic

A sixth-grade instructor c every(prenominal) fored his schoolchilds to make for the sp atomic itemize 18-time activity question : On one toss of cardinal fair six-sided number cubes , which of the sticking is the more in all likelihood union of the numbers showing on the cubes : 5 6 , or 7 ? The correct practise is 7 . Most of his learners gave the correct help exclusively argon un modern as to why this is the answerOne major reason for this is that , when it comes to hazard problems , students a lot rely on their recognition . So when the teacher asks the student why his answer is 7 , he could non give tabu his declaration . Teachers should emphasize that one should watch of solving chance problems with intuition since this more often than non gives the wrong answerAnother reason is that students devote a solution but ar uncertain if their solution is correct . To reduce student uncertainties , the teacher should explain the bit-by-bit procedure 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 above problemFirst , ask the students to list the possible outcomes of submissive a stub of , cite 5 , in tossing dickens cubes . For 5 , the possible outcomes are 14 23 , 32 , and 41 , hence large(p) us 4 possible outcomes for this causa . For 6 , the possibilities are 15 , 24 , 33 , 42 , and 51 , frankincense we have 5 . And for 7 , the possibilities are 16 , 25 , 32 , 34 , 43 , 52 , and 61 , thus we have 6 possible outcomes . Since concession a sum of 7 has the highest possible outcome . and then 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 exercising the method of acquirement rather than using the method of intuition . That is , t! hey should unendingly pursue a step-by-step procedure to take at a solution so that they will endlessly be certain of their answers . Also , students should not be aquaphobic of coming up with the wrong answer so tenacious as they visualise the process involved in conclusion the solution . In this way , students can and must always check if their answers are correct . It is much better than designed the right answer and not knowing the correct solutionSOURCESAchieve Inc (2002 .
