In this lesson, students will explain patterns in the number of zeros of the product when multiplying a whole number by 10. Recognize that in a multi-digit whole number, a digit in any place represents 10 times as much as it represents in the place to its right. Multiply whole numbers by 10. This lesson is directly aligned to work students did in Grade 4. Thus, it can be combined with the next lesson if they seem to have mastered this skill already and will not be challenged by this content.
