Two things I built, and you are welcome to both.

Neither of these is a marketing exercise. The practice engine is free and will stay free. The field guides are the written form of how I teach a topic from the beginning.

Free, no charge, ever

The Insight Bay Practice Engine

I wrote this myself. It is a curriculum aligned practice engine covering Grades 1 to 12 across four national curricula, with a worked solution behind almost every question.

  • 229 topic banks across 12 grade levels
  • Over a million questions, counted from the bank rather than estimated
  • Five mastery levels per topic, so a child can see the ground move
  • Sign in with an email so progress is saved between visits

The written form of the teaching

The Insight Bay Field Guides

Eight volumes. Each one takes a single year of algebra or geometry and works it through the way I would work it through in class: the rule, why the rule has to be true, the classic traps, and an Exam Lab with every solution shown.

  • Around sixty pages a volume, written and typeset in house
  • Every formula derived rather than asserted
  • A full Exam Lab with twenty four questions and worked solutions
  • Two editions of every page: Study for print, Screen for dark. Both included with one purchase
  • Instant download, yours to keep

$79 a volume, or $349 for the complete Library.
