Understanding gradient / slope
Connects steepness to horizontal and vertical change before the formula appears.
It demonstrates the portfolio’s core claim: a symbolic rule becomes easier to retain when its visual meaning is made inspectable first.
I’m Hoang Viet “Victor” Tran—a Computer Science graduate, Master of Teaching (Secondary) student and independent tutor. My strongest evidence is public and inspectable: 65 Australian Curriculum Mathematics explanations.
Available for online and practical Perth opportunities
These featured lessons show different representation choices. The complete library below contains every verified public explanation—not a hand-picked illusion of range.

Turns signed-number operations into direction and movement before consolidating the rule.
Separates centre from spread and asks which summary is useful in context.
Reads the diagram as evidence about distribution—not as decoration.
Builds a model, differentiates it and interprets the stationary point in context.
Organises notation and spatial reasoning into a repeatable solution sequence.

Stage 01 / 05
The learner may remember “rise over run” but reverse point order, ignore direction, or treat the sign as an arbitrary rule.
“Show me what changes as you move from the first point to the second.”
A student should leave with more independence—not merely a page of answers completed beside a tutor.
The check becomes the next diagnosis.
I accept work where I can prepare properly, communicate clearly and help the learner become more independent.
Professional status: Current Master of Teaching student; not yet a registered teacher. Senior Mathematics: enquiries considered after confirming the course, topic and preparation requirements.
The library is built through repeatable curriculum research, visual design, recording and checking. It is evidence of preparation and explanation craft—not presented as a substitute for learner outcomes.
Academic background, language proficiency, public teaching work and child-work readiness—kept distinct so each claim says exactly what it proves.

“The way you taught me to use contrasts, examples, and move from personal ideas to more general ones was so helpful… You constantly encouraged me by pointing out my strengths, and that gave me a lot more confidence.”
This testimonial reflects the learner’s experience. It is not presented as proof that tutoring caused a particular test score.
