Choose Your Lesson

Geometry for high school. Every task and every figure was written by a teacher before you got here — you choose which of them go on the sheet, and the finished documents come out ready to copy.

  1. Pick a lesson — from the units on the left.
  2. Build the lesson you want — start from easy, medium or hard, then add or drop whatever you like, activity by activity and task by task.
  3. Print — a student worksheet and a lesson plan you can open in Word.

Who makes this

We are Aleksei and Anastasia — one family, living in New York. We built this because putting together a good geometry lesson takes an evening that a teacher does not have, and doing it three times over so that three different students each get something they can actually do takes an evening nobody has.

There is no company here and there never will be. Two people, and the site is free.

What you can change in a lesson

  • Three levels on every task — easy, medium and hard, judged by the author when the task was written. Take one level, or mix them: a class is not one level.
  • More than one way of teaching the same thing. Where an activity has been written in more than one style, you choose which one your class gets — the one that leans on what they already know, or the one that does not.
  • As much practice as you want, or as little. Some lessons carry nearly thirty practice tasks; you take three of them or all of them.
  • A summary and a cool-down, chosen the same way, so what a student keeps and what you use to see whether it landed are both yours to pick. You can add a line at the foot of the cool-down asking the student how well he thinks he understood.
  • Going Deeper — the part of the lesson that goes past what the standard asks for. No ready-made set takes it, so it is never on the sheet unless you put it there: it is waiting for the class that finishes early, or the student who wants the reason and not just the rule.

This is being built, and it shows

The course is being written lesson by lesson. What is coming:

  • Answers — the worksheet again with the work filled in, so you are not solving your own sheet at eleven at night. None of the lessons has them yet.
  • More kinds of activity in each lesson, so there is more to choose between.
  • Slides for each lesson, if they turn out to be worth having.

Tell us what you think

A task that reads oddly, a figure that is wrong, something you wish the site did — any of it. Tell us what you think is at the foot of the panel on the left.

One press, one box, and send. No address, no account, nothing to fill in — we do not ask who you are and we cannot write back, so say what you actually think. Both of us read everything that arrives.
