Mathematics needs less equipment than any other subject — but the little it needs, it needs every day.
Every class
- Your journal or binder (see Math Journal for what goes in it)
- Pencil — mathematics is written in pencil, because first attempts matter and pen makes people afraid of them. An eraser you barely use.
- A ruler that lives in your bag — tangent lines and vector diagrams are drawn, not implied
- Your scientific calculator (the class set stays in class; having your own means your muscle memory is always on the same buttons. Know where your mode button is: the derivative of is in radians only, so a calculator quietly left in degrees breaks every sinusoidal derivative in this course — it is still the single most common source of wrong answers, and this year the stakes are higher)
Sometimes, and I’ll say when
- A device with a browser, for Using Desmos days — school devices are available if you don’t have one; nobody needs to buy anything.
- Grid paper for sketching units. A stack lives at the back of the room; take what you need — a curve above its own sign chart, or two vectors and their sum, both deserve better than freehand axes.
The phone rule
Phones are calculators of last resort, and they are terrible at it — the notification that arrives mid-problem costs more than the arithmetic saved. Bags, not pockets, during work time. If your phone IS your Desmos device for the day, it stays in front of you with the one tab open.
Forgot something? Borrow from the back table, return it at the bell, and nobody will ever make it a thing. Coming to class matters more than coming to class perfectly equipped — see Getting Help if gear is ever genuinely hard to come by, and we will quietly sort it out.
