It is especially true that boys may have to be prevented from dominating. Thorne Grammar, UK, Year 7 Boys tend to press to the front. When the students have been captured by the task, which may not have been solved as yet, offer each pair a set of cut out pieces. Very soon one pair will solve the problem and the flood gates will open. As each group completes their Sphinx, give them a strip of tape about 10cm long and ask them to join the pieces - but not too securely because they will have to take the tape off again later.
Recording Ask the students to record their solution on the triangle dot paper.
Half a sheet per student is sufficient. Extension Gather the students at the centre of the room again. This time use one of the students' Sphinxes made from four cut out pieces. Compliment the students on solving the puzzle and emphasise that we have used four Sphinxes to make a Sphinx. It won't be long before someone suggests that four of these ones could make the next size Sphinx.
