First bday party - acitvities for kids

My daughters bday party is on sept 1, and we only have about 10 kids we are doing it at a community centre party room. I’m not sure what to do for activities. I feel the age group is young for balloons and face painting.

The oldest kids I have are 9,7, 5 and then the rest are 1.5 to under 3 years old is the majority. Anyone have ideas I was thinking should I go to dollar store and get crayons and colouring? Will they even sit ? Not sure 🤷🏼‍♀️ thanks !
