A useful starting point
Start with the labelled examples in our combination guide. Change one card and explain what happens to the pattern. Use the reference for your variant to check the result.
Try it in practice
Keep a record of two arrangements and describe the difference. Do not rush into a complete hand until you can explain the smaller groups clearly.
Take one idea forward
Choose one question to revisit next time. Use the current rules for your format and keep the session comfortable for everyone.
