Understanding Decimal Place Value

The video tutorial explains the concept of place value in the decimal system, emphasizing how the position of a digit affects its value. It uses models to represent decimals and addresses common misunderstandings. The tutorial compares the values of digits in different decimal places, including mixed decimals, and analyzes how digit values change when shifted. The lesson concludes with a summary of key points on comparing decimal values.
