Life at Encarta
A class where maths feels good
Small enough to know every student by name, focused enough to get real results. Questions are welcome, mistakes are part of the plan, and friends push each other forward.
The Encarta Method
The world's best ideas in maths teaching, in one class
Methods from Singapore, Japan, Stanford and cognitive science, adapted for the Sri Lankan syllabus. Students don't just memorise steps. They understand them, and the understanding sticks.
Master it, then move on
Maths is a staircase. Missing one step makes every later one wobble. Short checkpoints catch gaps early so no one is left behind on Pythagoras because of fractions.
Track your own skills on the Mastery Map below ↓
Every mistake becomes a lesson
Students keep a mistake notebook: the wrong answer, why it happened and the fix. Before exams, it becomes the most valuable revision book they own.
Mistakes are data, not failure.
Watch at home, solve in class
Short concept videos before class mean more class time goes on problem solving with Sir beside you, the part that's hard to do alone.
Class time is for doing, not copying notes.
"Not yet" beats "I can't"
Nobody is "not a maths person". Lessons use low-floor, high-ceiling problems that everyone can start and strong students can push further.
Confidence first. Marks follow.
Streaks, XP & badges
A daily 2-minute puzzle builds the habit. Students earn XP, keep streaks and unlock badges, so practice feels like a game, not homework.

Cognitive science · spaced retrieval
Beat the forgetting curve
Without review, we forget most of a lesson within days. Encarta recap quizzes return to each topic after 1, 3, 7 and 21 days. Each recall makes the memory stronger, so by exam time it's yours for good.

FAQ
Questions? Answered.
Which grades and mediums do you teach?
Grade 6 through Grade 11 (O/L), in Sinhala and English medium. Each grade has theory classes, and O/L students also get revision and past-paper classes.
Can my child join in the middle of the year?
Yes. A short placement chat helps Damith Sir see where your child stands. Any gaps get covered with catch-up practice so they can follow the class confidently.
How do the weekly parent reports work?
Every week, parents get a short WhatsApp update with attendance, quiz scores and the topics to focus on. Nothing to install, it comes to the number you register with.
What are the class fees?
Fees depend on the grade and class type. Message on WhatsApp or call 071 772 9565 for current fees and seat availability.
What if my child is weak in maths?
That's exactly who this method is built for. Concrete-first explanations, step-by-step mastery and a "not yet" mindset help students who think they're "bad at maths" discover they aren't.
