Understanding the functions of body parts follows on from understanding the functions of objects.
Talk about some basic parts of the body and their functions (e.g. hands, feet, mouth, eyes, nose). Aside from the more obvious functions, can your child name other more ‘uncommon’ actions (e.g. tip-toeing)? Use the images to support learning. You can act some of the actions and see if your child can guess what it is. Alternatively, you can say the action word and ask your child to act it out.
