A sign, representation or prerequisite gap leaves a different trace. We read the line instead of erasing it.
Evidence: student explanation + saved work
Proofline builds a visible trail from the first uncertain line to an independent explanation - aligned to the student's actual Canadian course.
A mark tells you what happened. A reasoning trail helps decide what to teach next.
Our online tutoring is built for Canadian students who need a course-aware plan, not a generic level label. We begin with current work, a short diagnostic hypothesis and the student's own explanation. The tutor makes one mathematical decision visible, then returns the pen. Each lesson ends with an independent check and a dated next question.
Proofline is a tutoring studio, not a school, assessment provider or grade guarantee. We do not invent testimonials, tutor availability or success rates. Fit, scheduling, instructional needs and price are confirmed in writing before service begins.

A procedure may fail because the concept, representation, prerequisite, notation or attention load broke first. More repetition is only useful after the story is tested.
Immediate accuracy can rise before learning lasts. Our notes separate guided success, independent familiar work, delayed retrieval and transfer to a new form. The chart is an illustration of the framework - not a claim about results.
Read the progress evidence standard →Select a point to see the alignment question. The student's current course, teacher instructions and official provincial source remain the authority.

Fractions, ratios, integers and early algebra are connected through models the student can explain.
