A hundred-flat is ten rods — a 10×10 square of a hundred ones; a rod is ten; a cube is one. Count the flats by hundreds, the rods by tens and the cubes by ones, so two flats, three rods and five cubes make 235.
Quick way to teach it: Work biggest to smallest: hundreds, then tens, then ones. Jotting the three digits in labelled columns — H | T | O — as you count keeps a 235 from turning into a 253.
Work biggest to smallest: hundreds, then tens, then ones. Jotting the three digits in labelled columns — H | T | O — as you count keeps a 235 from turning into a 253. Print a fresh sheet, read a few piles together each day, and check with the answer key — short, regular practice beats one long session.
This is usually taught in Grade 2 & Grade 3. A hundred-flat is ten rods — a 10×10 square of a hundred ones; a rod is ten; a cube is one. Count the flats by hundreds, the rods by tens and the cubes by ones, so two flats, three rods and five cubes make 235.
Place value is the rule that a digit's position gives its size: in 235 the 2 means two hundreds, the 3 means three tens and the 5 means five ones. Base-ten blocks make it concrete — a unit cube is one, a rod is ten ones, and a flat is a hundred ones — so kids can count the blocks and read off each digit.
