Try to solve some (or all) of the following problems and bring your answers to school! If there are 24 hours in a day how many hours are there in a week? How many cents do you have in $5? If you cut a square diagonally from corner to corner you get four right-angled isosceles triangles. How many different shapes can you make by fitting the four triangles back together? You may only fit long sides to long sides and short sides to short sides.

The whole length of the side must be joined.

Can you draw a straight line across the centre of a clock face so that the numbers on both sides of the line have the same total?
