Part 1 of 26

Getting started

Cogito teaches math, reading, science and life skills, from pre-school up to the last year of high school. A math lesson is not a video and not a page to read. It is something your child touches and changes, and the answer changes with it. Science and reading lessons are picture books, read a page at a time, with a question to answer as they go.

You can try it before anything else

You do not have to sign up, pay, or fill anything in to see whether Cogito suits your child. Three things are open to everybody:

  1. The first chapter of every course. Every subject, every grade. Open one and read the whole thing.
  2. All of Life Skills. Every lesson, free in full.
  3. The lesson on the front page. The home page has a real lesson figure on it, and you can play with it without leaving the page.

When you want everything opened up, sign in. Until December 31, 2026, signing in opens every course, free. After that, signing in gives you seven days free. No card is asked for either way, and nothing is charged.

Your first five minutes

Here is the shortest path from arriving to watching your child do a lesson.

  1. Open cogitolearning.com.
  2. Under Try it — Grade 3 · Fractions, change the number of equal parts and watch the circle cut itself again. Tap a part to shade it. That is what every math lesson is like.
  3. Tap Courses in the blue bar at the top. Every course is on one long page. The buttons at the top, Math, Science, Reading and Life Skills, jump to each subject.
  4. Scroll to your child’s grade and tap the course card.
  5. Tap Start lesson 1. The first chapter is free and always will be.
The home page. The lesson figure to try is at the top, and the rest of the page is below it.

What you will need

A phone, tablet, laptop or desktop computer, and an internet connection. Anything made in the last several years will do. There is nothing to install and nothing to download.

Is my child too young or too old?

Math runs from pre-K, which is roughly ages three to four, up to Calculus and Differential Equations. Science runs from Kindergarten to Honors Physics, and Reading from pre-K to Grade 5. If you are not sure which grade to choose, a short test can suggest a course and chapter: see Finding where to start. The chapter on helping your child explains why starting slightly too easy is better than slightly too hard.
