Hello! This is a great way for learners to practice different ways to write a three-digit number. Just write in a three-digit number and you're off!
The four ways to write a number on this document include drawing a picture of the number (base 10 blocks is common), writing the number using words, writing the number in expanded form, and writing how many tens and how many ones in the number.

Rationale of Design
When I design, I strive to provide simple, "clean" documents. Limiting visual distractions will help users filter out unnecessary stimuli so that they can focus on important information.
