Mastering 3-Digit Addition with Place Value

Miss Lewis teaches how to add three-digit numbers using the place value strategy. The lesson begins with a review of writing numbers in expanded form, using the number 482 as an example. Students learn to identify the value of each digit based on its place. The lesson then demonstrates adding two sets of numbers, 234 and 162, and 657 and 321, by breaking them into hundreds, tens, and ones. The video concludes with a summary and directs students to additional resources for further learning.
