Lesson Plan of LCM Using Prime Factorization / Division Method Mathematics Grade V Students’ Learning Outcomes ·          Find LCM of four numbers, up to 2 digits, using prime factorization method. ·          Find LCM of four numbers, up to 2 digits, using division method. Information for Teacher ·          Since the students have done both factorization and division method for finding H CF, so they won’t find this difficult. ·          First go with three numbers questions and explain both methods, then individual or group work and then discuss on four numbers questions. ·          When any number is used to multiply with the set of natural numbers {1, 2, 3, ……}, the product of that number with each of the natural numbers is called multiples of that number, e.g...

Lesson Plan of Finding H CF of Three Numbers, up to 2 digits, Using Division Method Mathematics Grade V Students’ learning Outcomes ·          Find H CF of three numbers, up to 2 digits, using division method. Information for Teacher ·          There are many methods of finding H CF 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 H CF of these numbers can be found by using division. ·          There are two methods of division to find H CF, 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 div...
