This one isn’t so much an activity for students as a method of signposting what everyone is supposed to be doing.
The idea is you cut out the arrow and use a paper pin to stick it to the clock face so that you can turn it. Whenever the teacher moves to a new activity they turn the arrow so the students can see what they are supposed to do.
Teachers can use this with very young learners to make sure they know the activities that are going on in the classroom.
