Understanding Place Value Concepts

This video tutorial introduces the concept of place value for first graders, focusing on composing and decomposing numbers using place value blocks. It explains how to represent numbers like 33 and 112 using tens, ones, and hundreds, and demonstrates how to break these numbers down into smaller parts and reassemble them. The tutorial uses visual aids like 10 rods and 100 flats to help students understand the structure of numbers and how they can be manipulated.
