See Riku in Action

This is exactly what happens when your child learns one topic on Riku — from picking a subject to mastering a topic and burning a token.

💬 1. The Learning Session

Your child opens WhatsApp and starts learning. Riku guides — it doesn't just give answers.

1

Starts from what they know

Riku opens with a simple question the child can answer — building confidence. "What's half of 10?" Easy win. Then connects it: "That's a fraction — ½."

2

Scaffolds upward, step by step

Riku introduces one new concept at a time. If the child struggles, Riku breaks it down further. If they get it, Riku moves up. No skipping — every step must be solid.

3

Retrieval practice throughout

Riku doesn't explain and move on. It keeps asking: "Remember that rule from earlier? Apply it here." The child has to recall — the most powerful learning technique.

Hey! Ready to learn fractions? 😊 Let's start simple. What's half of 10?
Student
5!
Riku
Exactly! 🎉 So half of 10 = 5. Mathematically, we write that as ½ × 10 = 5.

Now try this: what's ⅓ of 12?
What's happening: Riku starts from a concept the child already owns (½ = half), then extends it. No new vocabulary until the idea is comfortable.Riku mulai dari konsep yang sudah dikuasai anak (½ = setengah), lalu mengembangkannya. Tidak ada istilah baru sampai idenya nyaman.

4?
Riku
Nice! ⅓ × 12 = 4 ✅

Now let's try something trickier. What's ⅖ of 15?

Hint: first find ⅕ of 15, then multiply by 2Bagus! ⅓ × 12 = 4 ✅

Sekarang coba yang lebih menantang. Berapa ⅖ dari 15?

Petunjuk: cari dulu ⅕ dari 15, lalu kali 2
Student
Hmm... ⅕ of 15 = 3, so ⅖ = 6?Hmm... ⅕ dari 15 = 3, jadi ⅖ = 6?
Riku
Perfect! 🙌 You just solved a two-step fraction problem.

Let's practice three more to lock it in. Ready?Sempurna! 🙌 Kamu baru saja menyelesaikan soal pecahan dua langkah.

Yuk latihan tiga soal lagi biar makin mantap. Siap?
What's happening: Riku uses retrieval practice — the child must pull the answer from memory, not just read an explanation. Each question builds on the last.Riku menggunakan retrieval practice — anak harus mengingat jawaban dari memori, bukan sekadar baca penjelasan. Setiap soal lanjutan dari soal sebelumnya.

⏱️ 2. Spaced Repetition — The Memory Lock⏱️ 2. Spaced Repetition — Kunci Ingatan

The next day, Riku brings it back — right before the child starts to forget.Besoknya, Riku munculkan lagi — tepat sebelum anak mulai lupa.

Nice, still got it! ✅

Now try this: A pizza has 8 slices. You eat ⅝ of the pizza. How many slices is that?Mantap, masih ingat! ✅

Sekarang coba: Sebuah pizza ada 8 potong. Kamu makan ⅝ bagian. Berapa potong yang kamu makan?
StudentSiswa
5 slices!5 potong!
Riku
🔥 Perfect. You're not just memorizing — you're actually applying fractions to real situations.

Let's level up: comparing fractions. Which is bigger: ⅔ or ¾?🔥 Sempurna. Kamu bukan cuma hafal — kamu bisa pakai pecahan di situasi nyata.

Naik level: membandingkan pecahan. Mana yang lebih besar: ⅔ atau ¾?
What's happening:Apa yang terjadi: Spaced repetition revisits concepts at scientifically-optimal intervals. Day 1: learn. Day 2: review. Day 5: review again. Day 15: one more. By then, it's permanent. This is how elite tutors work — Riku just automates it perfectly.Spaced repetition mengulang konsep di interval optimal secara ilmiah. Hari 1: belajar. Hari 2: review. Hari 5: review lagi. Hari 15: sekali lagi. Setelah itu, permanen. Beginilah cara les privat premium bekerja — Riku hanya mengotomatiskannya dengan sempurna.
