Make believe play involves children recalling pictures they have built up in their mind from past expereinces. Whether it is their mum paying for goods at a supermarket or a nurse bandaging their knee at the doctor's, with imaginary play children recreate these scenes they have built up in their heads and practice solving problems that are often part of these pretend scenarios. In observing, discovering and carrying out deductive reasoning, pretend play is critical for cognitive skills and helping children build the ability to solve problems and draw their own conclusions. The children this week have certainly been doing this. From dressing up in costumes, using bags, hats and jewellery, making a 'park with a slide' out of crates and guttering, to using conkers as ice cream, the children have negotiated roles and mutually agreed different terms.
