First, students will learn how to multiply whole numbers by powers of ten. For example, \(67 \cdot 10^5.\) This combines two skills: evaluating powers of ten and multiplying whole numbers by powers of ten. Here's a lesson, and here's practice. Next, students will learn how to approximate with powers of ten. For example, which is closer to \(318,900,000:\) \(3 \cdot 10^{8}\) or \(3 \cdot 10^9?\) Here's a lesson, and here's practice.
