, Teacher Notes
The Algebra Case Files covers a complete first pass through solving linear
equations: one-step equations, two-step equations, equations with the
variable on both sides, equations involving brackets, and forming equations
directly from word problems.
Each case opens with a short Discovery Briefing that introduces the concept
from first principles, so no separate lesson is strictly required beforehand,
though this book works equally well as first teaching, exam revision, or an
independent extension activity.
Expect approximately ninety minutes to two hours of engaged work for a
typical student. Every puzzle answer, along with a full worked explanation,
is provided in the Complete Answer Key page.
The Algebra Case Files includes a Certificate of Achievement. Upon
successful completion of all five cases, the certificate may be signed and
awarded by the teacher, tutor, instructor, or parent.

, Welcome to the Adventure
The trophy case in the main hallway is empty. The Grand Equation, the
engraved plaque Riverbend's Math Club has held for six years running, is
gone, and the Regional Competition begins in two days.
Taped to the empty glass is a single note: 'Solve your way to me, if you can.'
It is signed only, 'The Puzzle Phantom.'
