Frequently asked questions

What age is Grade 1 Mixed Practice designed for?

Grade 1 Mixed Practice works best for children aged 3 to 8 — from playful first exposure in kindergarten to confident fluency before Grade 1 and 2. Younger children start with shorter sessions and plenty of help.

How long should a daily Grade 1 Mixed Practice session be?

About 10 minutes. Short, frequent practice builds stronger memory than one long weekly session, and it keeps the experience feeling like play rather than homework.

Does Grade 1 Mixed Practice require any parent preparation?

No. Each session is self-explanatory: children see the content, hear the model and practise with instant feedback. Parents can simply sit alongside for encouragement — or enjoy the coffee while it lasts.
