This
activity is good for helping pupils to work and talk together.
It will encourage them to 'play' with 25 objects and
give reasons for choices.
Possible approach
After saying the riddle orally, you may wish to
display it on a screen or have it written on a board so everyone
can see. Allow pupils to choose whatever resources they
think they'll need to try to find a solution and
encourage discussion.
Key questions
Tell me about your lines.
Possible extension
Children could find a variety of answers and create new
problems that are similar for others to do.
Possible support
Any help that will enable the pupil to talk openly would be
good.
