About Rounding to Nearest Ten and Hundred
Place value is the idea that a digit's value depends on its position within a number. The "3" in 30 is worth ten times more than the "3" in 3. This concept is the backbone of our entire number system and is essential for understanding how multi-digit numbers work.
Rounding to tens and hundreds enables quick estimation of multi-digit calculations. It also develops number sense by teaching students to think about which "friendly number" a given value is closest to.
What Your Child Will Learn

Use physical bundles: group 10 pennies, straws, or blocks together and call them "one ten." Then show 3 tens and 4 ones to represent 34.
Play "build the number" — say a number and have your child show it with tens and ones using objects or drawings.
When your child sees a two-digit number, ask: "How many tens? How many ones?" until it becomes automatic.
Connect to money: a dime is worth 10 pennies, which is a perfect real-world model of tens and ones.
