| 内容記述 | Teaching Method of the Least Common Multiple in Elementary School Mathematics：Visually understand methods of the least common multiple of two integers that are not relatively prime Learning the "least common multiple" in "the properties of integers" in the fifth grade of elementary school leads to "addition and subtraction of fractions". However, there are some students who are not good at "addition and subtraction of fractions" because they cannot find the "least common multiple" quickly and appropriately. In particular, some students seem to believe that the least common multiple of two integers is the product of the two numbers. Therefore, teachers must consider how to help students visually understand the least common multiples of two integers that are not relatively prime, by "decomposing a number into the product of the two numbers" and "recognizing the product of the two numbers as the number of blocks"，before learning "addition and subtraction of fractions" . | |||||||
