we work out a method of rotating through the groups so everyone gets to see 'most'
of the puzzles. Often this involves the children in each group choosing the three
'most interesting' or 'most challenging' puzzles and those three students go off
to show their puzzles to the next group.
puzzles are then stored in a central location in the room for a week (if the
children and parents are cool with that) and you'll be surprised how many
students drift over to try and solve their favourite puzzle.
other beauty of this activity is that you get to see which puzzles work and which
do not. Which puzzles are challenging and which are not. Then you have some more
tools for your 'Teaching Toolbox'.
