📖 Teacher note:
Use Digit Cards to show how each digit in a number represents a different value based on its position. Switch to Dienes Blocks (also known as base ten blocks) for a concrete visual — hundred flats, ten rods, and unit cubes — which helps students physically see why 3 in 347 means 300, not 3 and connect place value to expanded form.
