💯 3-Digit Numbers & Place Value: Hundreds, Tens, Ones & Three Forms 🏰

Welcome to the grand palace of place value! When we add one to ninety-nine (99), we open the magical doorway to three-digit numbers and reach one hundred (100)! In this fundamental lesson, second graders explore the three rooms of the place value house: the Ones room on the right, the Tens room in the middle, and the Hundreds room on the left. Students learn the vital difference between the place value (the position name: hundreds, tens, or ones) and the value of a digit (its actual worth). For example, the digit 5 in the ones place is worth 5, in the tens place it is worth 50, and in the hundreds place it is worth 500! We also master writing numbers in three standard ways: standard form, expanded form, and word form with complete confidence.
