Great suggestions given :)
If you know your children's (key children's?) interests it will be far easier to plan an activity that will engage them.
Who really enjoy's cooking/mixing/foraging for play in an outdoor 'mud' kitchen - maybe take some herbs in?
Sand tray or water tray activities - who likes pouring, filling, building? maybe add ocean type animals, sandcastle flags?
Playdough - do children make their own? add a theme to the cutters and suface embellishments eg. flowers, leaves and bumble bees
Paint is always a great medium to change up - offer different sized brushes - huge to tiny. Colours, add texture to the paint eg. sawdust, glue and glitter.
Home corner - dressing up clothes
Hope this helps a little, there's a
creative planning sheet here if it helps you to focus on learning objectives.
