For parents and teachers: Level 1 suits many children of about 5 to 7, Level 2 about 8 to 10, Level 3 about 11 to 13, Level 4 about 14 to 16 and Level 5 about 17 to 20. Most learners do best a level or two below their age at first. The books never print an age, so nobody has to read a book marked for someone younger. Reading progress stays on this device; nothing is sent.
Why these books
Built for a learner on their own
- It expects your wrong answerEach wrong choice says what you may be thinking and which chapter fixes it.
- Every picture is exactDrawn by hand in style, exact in every measure. A shadow is as long as the Sun makes it.
- Made for paperBlack and white copiers keep every line. A code on each chapter, such as M2.4.3, works without links.
- One file you can pass onEach book is one file that opens on any phone with no internet. Send it to a whole class.
- No age on the coverLevels, not ages. Start where you are. Going down a level is normal.
