Grade 5 - Multiplication - Multiplying Decimals with the Standard Algorithm

To multiply decimals using the standard algorithm, students often ignore the decimal points initially, multiplying as if they were whole numbers. After calculating, they place the decimal in the result by counting the total decimal places in the original numbers.

While this method is efficient, it’s crucial to understand the underlying logic: multiplying parts of numbers, not just whole values. Teachers encourage students to think critically about what each step represents, ensuring they grasp the concept, not just the procedure.
