Steps
5 steps, 5 of them in App Maker
You need
A computer or Chromebook with a mouse or trackpad. Nothing to buy and nothing to print.

$5 for one learner: every step, the App Maker activities that check the work, the printable lesson, and the certificate with a page of the learner's own work.

A drawn phone showing a quiz app. A blue bar says Question 2. Under it: Which planet is the biggest?, three blue buttons for Jupiter, Mars and Mercury, and the words Score: 1.

The 5 steps

These open once the kit is unlocked.

  1. 1Play it, then make it yoursIn App MakerEvery app you use is screens joined by buttons. This one is a small quiz with four screens. Play it the way a stranger would, then give it a name.
  2. 2Add a second questionIn App MakerA quiz with one question is over fast. Add a second one, and make every answer to the first question lead to it.
  3. 3Keep scoreIn App MakerRight now the app forgets everything. Give it a number to remember, make each right answer add to it, and show it on the screen.
  4. 4Win with a perfect scoreIn App MakerA perfect score should get something better than the start screen. Add a You win screen, and a rule that sends a player there only when both answers were right.
  5. 5Hand it to someoneIn App MakerThe person who made an app is the worst tester of it. Hand it to someone, watch them play it twice, and fix what they find.

Work on a computer. The apps need a keyboard and a bigger screen than a phone: a laptop, desktop or Chromebook. You can pay here and open the emailed link on the computer.
