# Base ten block facts for kids

**Base ten blocks** are a tool to help students learn concepts in mathematics such as arithmetic and place value.

They are also known as **multibase arithmetic blocks (MABs)** or **Dienes blocks** after the Hungarian mathematician Zoltán Pál Dienes, who told others about using them.

## Use

These blocks come in four different sizes and represent different values.

- Units represent ones
- Rods represent tens
- Flats represent hundreds
- Cubes represent thousands

Different sizes are used to make up a number. For example, 593 is made up of 5 flats (500), 9 rods (90), and 3 units (3). Addition and subtraction can be learned by adding or taking away blocks.
