Hi mum, for K2 in Punggol area, I see quite a few mums usually go for centres that focus on Singapore Math foundation + hands-on learning, not just worksheets because this age still need fun and engagement. Around Punggol, you can look at options like S.A.M Singapore Maths programme or Kumon, both have centres in the North-East and are quite common for preschool to primary transition. If you prefer something a bit more enrichment style (less drilling), there are also local tuition/enrichment centres in Punggol and Sengkang that do small group K2 maths readiness classes, so I would suggest going for trial lessons first to see which teaching style your child responds better to.
