Decimal Operations and Multiplication Concepts

This video tutorial is part of module 2, lesson 11, focusing on using place value understanding to perform whole number multiplication and convert results back to decimals. The lesson covers estimation and place value reasoning to find unknown products, converting decimals to whole numbers for multiplication, and applying the standard algorithm to solve problems. A complex multiplication example is provided, demonstrating decimal adjustment. The video concludes with encouragement to review and redo the exit ticket to reinforce learning.
