I have children who are reading CVC words. How can I stretch them?
Please resist the temptation to start systematically teaching GPCs.
Instead, give your budding readers access to great picture books and plenty of opportunities to develop their early literacy during continuous provision. This will be enough for them to fly when it comes to learning phonics in Reception.
Prioritise their other areas of learning. Let them play and enjoy Nursery and focus your attention on getting their friends up to their level.
