What kinds of lines and angles did you see in most living things? How about in most human-made things? Are there typical lines and patterns that show up in living things vs. human-made things? Any exceptions to this?
Living things: trees, plants, snow.
These items all have complicated fractal-like patterns to them, requiring more attention and focus when trying to draw them. They seem to have more dimensions to them and more detail to include. Angles seem to be pointing upwards, towards the sun, 45 degrees or smaller in relation to the main trunk. I thought my pine trees in the back were an exception with the pointing down stricture, but as I look out at the trees again, I realise my drawing is false and they actually point up! This is not an observation I have ever made before as I have always sketched these branches going down.
Human-made things: road sign, power lines, building, window, parking lot, road.
These items were very linear, many straight lines and near-90 degree angles, they took a fraction of the time to draw, and were very simple structures to add to a page.

I believe that the patterns in living things exist for optimal living conditions, plants and trees are built to sustain the weather, and be positioned in the right way to prioritise photosynthesis and optimize it. While humans are smart, we are nothing compared to nature, so keeping things linear and at simple angles makes construction and maintenance easier.
How might you use close observation and drawing or sketching to help your students learn about lines and angles?
This is a great way to start the conversation of the living world, and patterns and angles in real life, allowing students to draw the connections between math and the world.
Are there ways to experience lines and angles through whole-body movement or large body motions outdoors? In relationship to the living world?
I will continue to reflect on this. I did my drawing from inside as it has been -30 degrees Celsius this week, I was not able to sit outside while drawing. But I will be mindful of this when the polar vortex moves on and spending time outside is enjoyable again!
