The latest edition of the Guinness World Records annual was published recently, and it's always a good source of material for a lesson on superlatives and measurements. I used four videos featuring new records from the Guinness World Records YouTube channel for a jigsaw viewing activity. You can see one of them below, and the other three are listed on this worksheet. I also did a transcript of the videos which you can find here.
I decided against using the man with the world's longest tongue, but you might be braver than me!
