Writing Numbers Through 999
Writing Numbers Through 999 in Grade 4 Saxon Math Intermediate 4 Chapter 1 teaches students to translate three-digit numbers into words and back. For 625, first identify the hundreds digit (6) as six hundred, then read the last two digits together (25) as twenty-five, combining to get six hundred twenty-five. When a zero appears in the tens place, as in 803, skip it entirely and read only the hundreds and ones: eight hundred three. Hyphens connect the tens and ones digits for numbers 21 to 99. This skill prepares students for writing amounts on checks and formal documents throughout their lives.
