Introduction to Decimal Blocks
A major strength of the Digi-Block program is that students can model both whole numbers and decimal fractions at the same time.

The traditional blocks can be used to model whole numbers. Here we see 146 modeled with a block-of-100, four blocks-of-10 and six single blocks. |
 |
Using the tenth and hundredth blocks, we can model decimal fractions. Here we see .25 modeled with two tenth blocks and five hundredth blocks. |
 |
Because the tenth and hundredth blocks look the same as the single blocks, only smaller, the whole number digi-blocks and decimal fraction digi-blocks work together seamlessly! Here we see 146.25 |
