Learning Objective
I can read and write three-digit numbers.
Today we will learn how to read and write three-digit numbers. Math helps us solve problems and understand the world around us.
Three-digit numbers have a hundreds place, tens place, and ones place. In the number 347: the 3 is in the hundreds place (= 300), the 4 is in the tens place (= 40), the 7 is in the ones place (= 7). Total: 300 + 40 + 7 = 347 (expanded form). Reading three-digit numbers: say the hundreds digit + "hundred" + the remaining two-digit number ("three hundred forty-seven"). On a hundreds chart (1–100), each row increases by 1 and each column increases by 10 going down. Understanding hundreds is essential for addition and subtraction with regrouping.
Let's break this down step by step so it's easy to understand. Follow along with the examples, and don't worry if it takes some practice to get the hang of it!
Remember: Making mistakes is part of learning. If something is tricky, try again, look at the examples, or ask for help.
