Exploring Forms of Numbers in 5th Grade Math

The video tutorial explains four main forms of expressing numbers: standard form, expanded form, unit form, and word form. Standard form involves writing numbers using digits. Expanded form breaks down numbers using place values, either as decimals or fractions. Unit form combines elements of expanded and word forms, indicating the value of each digit. Word form involves writing numbers in words, considering the place value of each digit. The tutorial provides examples for each form to enhance understanding.
