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.
