Active Expressions are a bit like phones but they are much greater than phones!  We can use them in maths lessons for mental maths  and lots of other things.   We can do multiple choice quizzes,  write answers in words or type in  numbers  for answers.  We have our own Active Expressions with a number on the back so we know which one is ours.  Once we have answered each question the teacher can quickly see who has got it right by looking at a bar graph on the computer.
