How a game teaches

Here is what a game asks you to do. Not every game has every step.

Guess firstPick what you think will happen. Your guess is saved, not marked yet.
Find out by handPush the car, take the cell apart, stack the layers, and watch what happens.
See whyMost answers come with their reason. Hints wait until you tap I'm stuck.
Say it your wayIn half the games, you explain the idea in your own words, and the game checks for the key ideas.

Built on how people learn

The games use ideas from research on how people learn. Not every game uses all of them.

Learned means more than one lucky answerIn the games that keep a record, an idea counts as learned only after the first try is right in three different cases, on two different days.Learning versus performance · Soderstrom and Bjork, 2015

How each game is made

A person and an AI write each game ahead of time. Two separate AI checkers then read the sentences we list from each game, and a game goes on this site only when each fact they find has a source that a checker has read. No AI runs while you play.

  • Play together, and see what your child learned in the games that keep a record, one child at a time.
  • Print the games that have a paper version and try them at the kitchen table.
  • Your child's name stays in this browser. A survey you choose to send carries your answers and how far a game got. It asks for no name.
