Learn About Riddle Books


Riddle Books is aligned to a number of the Common Core Standards by the Center for Game Science at the University of Washington.

* Story problems come in all flavors like science fiction, magic, and animals to name just a few. This lets students discover favorites!
* Customized hints are at the ready to help students get themselves back on track.
* Students are not just completing story problems - they are also getting the tools needed to solve any story problem they encounter going forward.
* Riddle Books is designed to grow with player skill and "level up" as they do. This keeps everyone learning - but more importantly, keeps players having fun.

Riddle Books is designed to feature linear progression with some adaptive learning elements. Every student ideally will progress through each of the problem types. Older students will likely progress more quickly although it may take them a while to master setting up the models (this is both the fun and the challenge for many of the problems).

Technical Requirements

Riddle Books and the Teacher Copilot are completely free, and will work on any recent web browser. Any class with access to a PC, Mac or Chromebook can participate in the challenge. You will also want to make sure you have Flash Player 11 (or greater).

Tips for Playing

Riddle Books is aptly named. Some of the problems are quite enigmatic. We hope this will be viewed as a challenge and not a source of frustration.

As you play through the game, you’ll unlock new problem topics as you ‘master’ previous ones. Try to make as few mistakes as possible when submitting your answers to a problem and use the hint button as little as possible to unlock more challenging problems. You can also replay topics you ‘mastered’ before if you want more practice, there might be new problems in those topics you might not have seen. To replay old topics, exit out of the current problem and back in the level select screen. Select one of the shelves to open up the chapters and problem sets available for replay. If you click on a button with the word ‘Set’, you can see all the problems in that set you have finished. Ones without a star are problem you have not finished yet.

Here are some suggestions for making your Riddle Books experience smooth!

If you ever forget some of the game controls, while in the middle of a level, click on the yellow gear at the bottom left to open up the main menu. One of the options in the menu is named “Help”, open it and click on the “Controls” button to see the list of controls that you may need to solve the problem.

My student and I are stuck on a particular problem. What should we do?
1. Is there another way that this model or equation might be built? If so, try it.

2. Did I use the hints? At the end of the standard hints is a “Show Hint” button. Level one of the show hint is an example of the model where the letters represent the known numbers and the ? represents the unknown label. Level two of the show hint is a “cheat” hint. It will show you the correct answer but will not give you credit for the question. This should be used sparingly as it will cause the student to remain at the current level longer.

3. Am I reaching an uncomfortable level of frustration? Use the Skip Button. The Skip Button is available in the Options menu available in the lower left. Similar to the cheat button it should be used sparingly as it affects the student’s mastery statistics.
