Ruler Other applications include using it as a ruler, if you know each square is 5 cm then you can measure stuff. It has the added benefit that you can measure in at least 2 directions at the same time. Block Art You can color in the blocks to make pictures. In fact graph paper looking templates are created for knitters to use as a template. It’s kinda like pixel art. Games There is a game I played a bunch of times where you see who can make the most blocks. Each player takes a turn drawing a “1 unit” line on the paper. Whenever someone connects a line that makes a complete square t put the letter of their name in it and t get to go again. At the end of the game whoever has the most blocks wins. Though graph paper works I’ve usually played this using “dot paper”. Penmanship Graph paper can be useful when children are learning to write. The blocks help guide them draw tall and short letters the right size. Also helps with letters who’s parts go below the line like “p”. It’s not bad for adults who want to learn to write more neatly too. Crossword Puzzles Graph paper is great if you are trying to make your own crossword puzzles. Mazes Also great for making your own mazes.
This is what you need to be doing to achieve these goals: Read this post. Don't start with this and expect a clear understanding of the topic. Start by reading this post and then read/re-read this post. Take a deeper dive into learning about data and modeling it with linear algebra in Python. Then, follow this article, which shows you how to achieve the data transformations by using a graph model.
