Differentiated group task cards

I stick these cards on all my students books - this allows me to easily get all the students into two sorts of groups: ability groups via animal (squid = high, crab = mid, starfish = low) and into mixed ability groups using the parts of an atom. I have then stuck big pictures of each grouping round room so that when I ask students to get into groups they know exactly where to go. I have also stuck the animals onto my desk so help with giving out differentiated worksheets - each student picks up sheet next to their animal.
