Hi, open ended resources that the hildren can come and go from are good. Maybe use the question 'what skills are needed to take part in this activity' to help evaluate how inclusive the activity is in practice.
How about a
looking toys treasure basket - camera, magnifying glass,
kaleidoscope, glasses, binoculars, telescope.. this activity promotes equality and inclusion where an emphasis is placed on touching, feeling the resources, listening to them and exploring using the senses other than sigh. Hats are also a nice dressing up resource.
