Bryony's Triangle
Why do this
problem?
The practical aspect of
this task will
appeal to many children. It offers an opportunity for
learners to share their understanding of fractions with each other
as they work to solve the problem.
Possible approach
You could begin by watching the video straight through all
together and then talking about the task as a whole group so that
everyone feels confident to have a go. It might be worth
playing it again all through before handing out squares of
paper. You could then play the video a third time in short
sections as learners fold their own paper.
Alternatively, you could demonstrate the folding yourself if
you are not able to use the video in the classroom.
Once all learners have made the flower, give them a chance to
talk in pairs about the fraction part of the challenge. It
might be that at this point, more squares of paper are needed which
could be folded again and annotated. After some time, you
could ask pairs to join together to form groups of four so that
each pair has chance to explain their thinking so far.
You might give each group or pair a piece of large paper for
them to record their ideas, which could then be presented to the
rest of the class.
Key questions
How might you use the folds of your flower to help?
What fractions of the piece of paper can you see using the
folds?
How could you split the paper in half using the fold
lines? A quarter ...?
Possible extension
Possible support
You could encourage children to open out the flower and draw
lines on the square over the fold lines to mark halves, quarters
etc. You may want to have scissors and coloured pencils/pens
available too.
