2nd and 3rd class were given a scissors and a piece of A4 paper and they were challenged to make the page big enough so that they could fit their bodies through the middle of it. They tried lots of different strategies (some hbing to resist temptation of using glue or selotape) until it was solved. One child even managed to make one big enough so that all 2nd class boys could fit through it at once. This was using just one piece of A4 paper and a scissors!
