Understanding Number Forms and Values

The video tutorial covers how to read and write decimals to the thousandths using base 10 numerals, number names, and expanded form. It defines expanded form as breaking down a number into the sum of its digit values and word form as writing a number using words. Two examples are provided: 1.43 and 76.429, demonstrating how to express these numbers in both expanded and word forms.

What is the main focus of the lesson?

• Understanding fractions
