Place Value models (Up to the Hundreds)
𧱠Let's build a giant tower! We have tiny Cubes for Ones, tall Rods for Tens... but what do we use for the Hundreds block?
Do this: Read the concept below, then try the quiz or activity.
Concept
Our Base-Ten blocks are getting an upgrade.
π― The Giant Square Building Block: * Ones: Tiny little cubes. (1) * Tens: A tall rod made of 10 tiny cubes glued together. (10) * Hundreds: A giant flat square. It is made of 10 long rods glued side-by-side! (Or 100 tiny cubes glued together!). We call it a "Flat".
Example: How do we build the number 342? 1. Look at the Hundreds (3). We need 3 Giant Flats. 2. Look at the Tens (4). We need 4 Long Rods. 3. Look at the Ones (2). We need 2 Tiny Cubes.
If a picture shows 2 Giant Flats, 0 Long Rods, and 5 Tiny Cubes... the number is 205!
