Representing decimals

This document discusses representing decimals using base ten blocks. It begins by showing a set of blocks and asking what number they represent without providing enough context. It then explains that the blocks can represent different values depending on what the large block represents. The document suggests letting the large block represent 1 instead of 1,000 and describes what each smaller block would then represent - with the flat representing 1/10 and the long and small cube representing even smaller decimals. It concludes by asking the reader to try some practice problems using their own blocks or representations of the blocks.
