**Summary: **

Twelve–year old Robert hates mathematics and doesn’t see the power or beauty in it. That is until he spends 12 nights being visited by The Number Devil in his dreams. The subject comes to life through a series of explorations and metaphors and Robert discovers his passion for the patterns and wants to discover more. This is an illustrated novel with wonderful diagrams and formulae, interesting quirks of vocabulary and metaphor that has so many key mathematical concepts rolled out in one story it’s hard to document them all!

**Unit Sequence: **

The book is a novel organized as 12 chapters: one chapter representing each night Robert is visited by the Number Devil. A suggestion is to read aloud a chapter on the Monday, then explore the key ideas over the week and then re-read the chapter on the Friday. On the Friday have students document their new understandings gained that week. The copymaster contains a table that presents some of the key ideas in each chapter, a link to one investigative Figure Out Activity per chapter, and a suggestion of one other possible response activity.
