Session Structure

(In the photo: after-session vote for the best activity. Each child distributes 5 stickers.)

Typical Session

A typical session in the year 2025/26 had:

• Warm-up (10–15 min)
• Main topic (35–40 min)
• Break (10 min)
• Second topic or hands-on challenge (15–20 min)
• Game (15–20 min)

In 2026/27 we will slightly expand all the sections to make it 2 hours instead of 1h 30 min.

Warm-up

• 4–6 problems.
• Low to medium difficulty.
• Source: past maths challenges and olympiads; sometimes we make our own problems.
• In the year 2026/27 we will try adding 1–2 problems from previous topics to improve interval learning.

Main topic

• This is where we teach and learn new complicated stuff.
• 5–15 min of collective discussion (depending on the topic).
• Then children work with individual problem cards.
• Cards are designed to teach different aspects of the topic, and their complexity gradually increases from very easy to very hard.
• We help and support children individually during this work.

After the break

• We either have a second topic with minimal teaching, or a hands-on challenge/puzzle.
• Max. 2-minute discussion, then individual work.

Game

• At the end we play a game.
• The games are strategic, geometric, mathematical, spatial – fun, but not purely entertaining.
• Another important restriction is that the rules should be explainable in 2 mins.
