Fractions – Getting in touch with rational numbers

This 66-page book contains 90 interactivities. Interactive charts allow students to become acquainted with new content through exploration, and a wide variety of interactive tasks are provided for them to practice. All interactive tasks are designed to be adaptive, meaning the difficulty of the task can be matched to the individual students, and they provide immediate brief and precise feedback related to the task to each student. Some exercises are also designed with a hint system that the students can control on their own to display incremental hints about the solutions.
