Problem Types

Meet the Problem Types

There are seven problem types that your students may encounter in Riddle Books. Within each type there are several sub-types depending on what value(s) is missing and what value(s) is known. Click on each category headline below to jump to a visual demonstration of each type, or watch our YouTube playlist featuring all seven! Riddle Books is in constant development, so while some of these featured videos are from January 2016, keep in mind things may change slightly based on tester feedback!
