  • 16 Number Quests — levelled from the Million Warm-Up to the 15-digit Final Monster, each with steps to follow and an “I read it!” spot
  • A 7-day adventure map — which quests on which day, with tick-off spots along the way
  • Kate’s video lesson — she teaches the whole method herself, in her own fun way; just scan the QR code on the Start Here page

توضیحات بیشتر

بچه‌ها معمولاً در برابر کلاس‌های ویکند مقاومت می‌کنند؛ چون باید برای مهارتی وقت بگذارند که هنوز فایده‌اش را حس نمی‌کنند. اینجا اما کلاسی برای رفتن نیست و خروجی‌ای هم از بچه خواسته نمی‌شود — هر روز فقط یک قدم کوچکِ تازه می‌آید و مرور سریعی از دیروز، و بچه‌ها پیشرفت خودشان را تندتند می‌بینند؛ برای همین همکاری می‌کنند. نوشتن هم عمداً برای مرحله‌ای بعدتر مانده است — اول خواندن راه می‌افتد، بعد نوبت نوشتن می‌رسد.

Children usually resist weekend classes: they are asked to give up their time for a skill whose use they don’t feel yet. Here there is no class to attend and no output demanded — each day brings one tiny new step and a quick review of yesterday’s, and children see themselves improving fast, so they cooperate. Writing is deliberately left for a later phase — reading gets going first.

مکعبی که هر بچه‌ای داره و هیچ‌کس تمومش نمی‌کنه — حل می‌شه. پله‌پله، با سرعت خود بچه‌ها. شروع با مدل اصلی ۳×۳ · کارت‌های قدم‌به‌قدم + فیلم‌های آموزشی خود کیت · یک «تونستم!» واقعی — با اعتمادبه‌نفس · لیست انتظار باز است

More details

YouTube tutorials race through the steps and most kids quit confused. Kate teaches the way she teaches everything: tiny visual steps, playful, unhurried — until the cube clicks and the child has genuinely finished something hard. And once the classic 3×3 clicks, a whole family of cubes is waiting: Kate solves about 3–5 of the main cube types herself, and Cube Lab grows with your child from the first cube to the next ones. If your child is keen to keep climbing, the same tiny steps continue to a few more cube types, with Open Tabs alongside until those click too — and by then, your child has learned the pattern language underneath it all well enough to chase new cubes independently.

آموزش‌های یوتیوب قدم‌ها را تندتند رد می‌کنند و بیشتر بچه‌ها وسط راه گیج می‌شوند و رهایش می‌کنند. کیت همان‌طور یاد می‌دهد که همیشه یاد داده است: قدم‌های کوچک و تصویری، بازی‌وار و بدون عجله — تا لحظه‌ای که مکعب سر جایش می‌نشیند و بچه واقعاً یک کار سخت را تا آخر رسانده باشد. و وقتی ۳×۳ کلاسیک جا افتاد، خانواده‌ای کامل از مکعب‌ها منتظر است: کیت خودش حدود ۳ تا ۵ مدل اصلی مکعب را حل می‌کند و Cube Lab همراه بچه‌تان از اولین مکعب تا مکعب‌های بعدی رشد می‌کند. و اگر بچه‌تان مشتاق ادامه‌دادن باشد، همان قدم‌های کوچک تا چند مدل مکعب دیگر هم ادامه پیدا می‌کند و Open Tabs کنارش می‌ماند تا آن‌ها هم جا بیفتند — و تا آن موقع، بچه‌تان زبان الگوهای زیرِ کار را آن‌قدر خوب یاد گرفته است که خودش مستقل دنبال مکعب‌های تازه برود.

New · A one-to-one project

One stubborn problem? We design the game that cracks it.

Tell us the one thing that keeps getting stuck — and Dr Kate Vojoudi designs a learning game or a fresh, creative method for your child alone, shaped around their age, their character and how they learn best. One problem, one child, one design made only for them.

  1. 1

    Tell us the problem

    Describe the one recurring problem in your own words — what happens, and exactly where it always stalls.

  2. 2

    Designed for your child

    Kate studies your child’s age, character and learning style, then creates a game or method built around that one problem — and no one else’s.

  3. 3

    The game, plus a parent guide

    You receive the finished game or method, ready to use — with a short parent guide so you can run it at home with confidence.

Problems families and centres bring us

  • “Addition just won’t stick — he counts on his fingers again, every single time.”
  • “In reading, she makes the same mistake on the same kind of word, over and over.”
  • “In maths, he always gets stuck at the exact same step.”
  • “The bedtime reading routine lasts two nights — then it falls apart.”
  • “We want a morning routine that actually happens — without the daily battle.”

Projects start from about $100. After a short evaluation, you get one exact fixed price — quoted before anything starts. A small, single-layer problem sits near the start of that range; a serious, multi-layer case can reach about $2,000.

One problem. One designed game. One fixed price — agreed before we start. If a project is designed to finish in three sessions, it finishes in three sessions — no open-ended monthly drip.

An educational design service — not therapy, assessment or diagnosis. Like any learning tool, what it becomes depends on practice at home.

Does your child…?

  • start homework only after a long battle?
  • take hours over work that should take minutes?
  • leave tasks half-finished?
  • lose things and forget instructions?
  • get pulled away by every screen and sound?

Ticked two or more? This was built for them.

Questions parents ask

No — Open Tabs is an educational skills program, not treatment, assessment or diagnosis. We practise five focus and executive-function skills through games and activities. It does not replace any treatment, medication or specialist program your child has, and we make no treatment promises.

The courses are open to all children — no diagnosis is needed. The structure (small groups, active game-based 60-minute sessions, a timer with a known end, clear rules) is designed so children who struggle with focus and starting tasks feel comfortable. Just remember: this is skills practice, not a treatment for ADHD.

No — none of those. In Session 1 we do a simple educational observation so we know each child’s starting point, and at the end of the term you receive a before/after report on the same five skills. That observation is educational only — it is not diagnostic or medical.

Groups are capped at 8 children — small enough for individual practice, big enough for group energy. There are two separate age bands: Focus Kids (ages 7–9) and Focus Lab (ages 10–12), because the methods and language differ by age.

A short weekly update, a before/after report at term’s end, and the planner system your child brings home — planner, reminder wall, two-minute morning ritual. Parents don’t sit in: the practice space stays the children’s.

We don’t promise grades — no honest program can. What we teach are the underneath skills school depends on: starting work, staying with it, remembering steps, planning and managing time. Families usually see the change first at home: fewer “I forgot”s, calmer homework, tasks actually finished.

That week’s update includes a summary of the skill and the home mission, so your child can practise at home and keep up with the group’s rhythm. Because each session is a live group activity, there are no group make-up sessions.

Each term runs at a partner school, centre or library in Toronto & York Region. Dates, venues and fees for the next term are announced to the registration list first — join the list below and everything lands in your inbox as soon as a term opens.

Missed sessions can’t be made up in a group program, but your child won’t lose the thread: you will receive that week’s home-practice sheet through Parent Companion. If a session is cancelled (weather, a centre closure, or our side), it moves to the term’s built-in buffer week — and if no buffer week remains, that session is credited.

The Number-Reading Workshop

Want your child to read a GIANT number like this one? Look at this number. In our 2-hour workshop, kids learn to read exactly this — out loud, calmly, correctly.

Can your child read this out loud?

trillions family billions family millions family thousands family ones family

Two hours later, they can. That’s the whole workshop.

Book your child’s seat

Big numbers are exactly where many children quietly get stuck. The digits blur into one long string, place value slips — and one misread digit throws off everything that comes after it.

One intensive 2-hour session, run by Kate herself and booked directly with her — not through schools or centres. With her playful “number families” method, children learn the one trick behind every big number: families — ones, thousands, millions, billions, trillions — whose members always line up in the same order, in homes with no names of their own. By the end of the session, your child reads any big number out loud, calmly and correctly.

And it isn’t only about reading: reading a big number correctly is the foundation for adding and subtracting big numbers correctly — every digit lined up under its own value, in its own column.

One session · 2 hours Small group Parents book directly

Held in a small rented room in Toronto & York Region. The next date and venue are announced to the registration list first — join the list to hold a seat.
