This download contains four sets of cards. Students choose a set and sort them into order by answering the questions. Then they try to do it faster using a different set, which has a different sort order.
The cards can either be used by individuals, pairs or small groups.
My favourite use is for two students to have different versions of the cards and race each other. They then check their answers, shuffle, swap packs and race again (quickest overall time wins!)
Solutions and instructions are included. Cut out card size is approx 65 x 90 mm.
