For a great group activity, try using a cube. Here's a Cube template. Print out the template onto A4 card, cut out and use in group activities. Put key words for your topic onto each cube face, learners can stick or sellotape the sides, work in groups. Roll the cube!
Example activity for any lesson: Add a key word to each face of the cube, learners must prepare a sentence using each of the key words.
Or try using two cubes in Maths - one with operators and the other with numbers.
Great to use in Functional Skills, or any class - to enliven the session.
