I use a directory 𝘹+1 for the academic year including Autumn 𝘹 and Spring 𝘹+1. (I feel super guilty for labeling the time interval using the right hand endpoint.)

I first saw "acute angle mazes" in some of the beast academy curriculum from AoPS -- super fun way to get people to think about angles

A colorful bag of Cosmic Crisp apples, with the tagline at the top that says "amazing flavor + infinite possibilities". The bag features a big painterly image of an apple with three icons that mention snacking, baking, and entertainment.

"infinite possibilities" is a wonderfully optimistic tagline for apples

The surface of an empty parking lot showing a few parking spots (outlined in yellow lines), part of a lamp post, and pools of water. The pools of water appear where the wheels of the car would be.

So the weight of the cars causes slight indentations where the wheels sit?
