Can you wrtite a list of all of the things that you think makes a good friend?
Ask your grown up to draw around you whilst you lie on a pavement or a big piece of paper (an old roll of wallpaper works well for this!). You can then decorate the body template either as yourself or as one of your friends that you have been missing.
Can you complete the 'All About Me' sheet. Your grown up could take a photo of the completed sheet and email it to the school email address so that it can be shared with your new teacher.
