Model Method & ProblemSolving• Model method is a synthetic-analytic process thatcan be used to express and solve structurallycomplex word problems:-This Method entailsdrawing a pictorial model and finding the so called“1-unit” from unitary method. Students will learnhow to identify known and unknown quantitiesand relationships among each - syntheticapproach, then logical steps are developed for thesolution of the problem – analytic approach.1/1/201211/19/2011
Example Problem #1: 3 out of 7 students in an Algebra coursepass a class quiz. How many students did not pass in a classof 91 students?Solution:Here a pictorial bar model is used to represent the whole, (total number ofstudents in the class). The whole is 7 units of which 3 units representsnumber of students passing the course.Therefore 4/7 of the whole students did not pass the course.7 units = 91 students1 unit = 91/7 = 13 students4 units will be = 13 x 491= 52 students failed the quiz.1/1/201211/19/20111unit
