Students creating visual directions

I have students create visual directions like how Lego sets have. A 100 day of school is coming up I like to give the students a 100 Legos. They must then create a visual directions. As they build I have them create directions a rough draft at first. Next they create a final color version. This is an example of a first graders " pirate ship" directions. I like the top right corner shows the drawing of a ship. Then using math counts how many Legos should be placed using arrows. Older students could probably write a little more.
