We begin by reviewing that scientific notation expresses a value as a factor multiplied by a power of ten. First, the video models how to multiply the factors. Next, we apply the Product of Powers Property, showing that when multiplying powers of ten with the same base, we add the exponents. After finding the product, students are guided to check whether the result is written in proper scientific notation. The lesson reviews the requirement that the factor must have one nonzero digit to the left of the decimal—in other words, the value must be greater than or equal to 1 and less than 10. If necessary, the expression is adjusted to meet this standard form. This concise, visually modeled lesson reinforces both the procedural steps and the underlying rules, helping students build confidence when working with very large and very small numbers. The content aligns with Common Core Standard HS.N-RN.A.2 for high school mathematics.\n
