Effective and Creative Lesson Plans ! For Teachers By Teacher

  LESSON PLANNING OF ADDITION AND SUBTRACTION OF FRACTIONS Subject Mathematics Grade 5 th Students` Learning Outcomes Add and subtract and more fractions with different denominators. Information for Teachers In the begging, numbers were counted in whole. Later on, to count the part of whole, the concept of fraction was given. Fraction number has two parts. Upper part is called numerator and bottom part is called denominator. Once you understand the concept of addition of fractions with different denominators, you can directly apply the addition process in following ways: (2 / 7 ) + ( 3 / 5 ) Find LCM of denominators and divide the LCM by denominator & multiply its quotient with respective numerators and we get: [( 2 x 5 ) + ( 3 x 7)/ 35] Solve the Parenthesis and we get: = [10 + 21] / 35 Solve Braces and we get: = 31 / 35 Teacher should also consult with textbook at all steps where and when applicable.

  LESSON PLANNING OF PROBLEMS INVOLVING HCF AND LCM Subject Mathematics Grade 5 th Students` Learning Outcomes Solve real life problems involving HCF and LCM. Information for Teachers HCF and LCM are of great importance in our daily life. We use HCF, when we have to make smaller parts of anything through division. We use LCM, if there are repeated events. Similarly we need the least common multiple to find a common denominator, for adding or subtracting fractions, and to write the fractions into simplest form, we need greatest common divisor. Practice more and more to the students, of finding HCF and LCM mentally. Review some tables to students, especially 12 x 12, 13 x 13, 22 x 22 etc. because if students are good at tables, they can make correct estimates. It`s good if these types of special multiplications are reinforced every now and then.

  LESSON PLANNING OF FIND HCF OF THREE NUMBERS, UP TO 2 DIGITS, USING DIVISION METHOD Subject Mathematics Grade 5 th Students` Learning Outcomes Find HCF of three numbers, up to 2 digits, using division method. Information for Teachers There are many methods of finding HCF of two or more numbers, e.g. through prime factorization or through division etc. If large numbers are given then it is hard to find all the common prime factors, in such situation, the HCF of these numbers can be found by using division. There are two methods of division to find HCF, one by continuous division process and second is Ladder Method. In continuous division process, from two given numbers, any one is taken as divisor and other is as dividend, and after division, now remainder is taken as divisor and the first divisor is taken as dividend and we repeat division process. The process keep continue until we get the remainder ‘0’. Hence the last non zero divisor is called GCD or HCF. If we ha...
