Maths revision

We looked through our weekend maths revision sheet.  There were a few questions that we needed to look at carefully.  In the perimeter question, don't try to go diagonally across squares, because the diagonal distance is more than 1 centimetre so the perimeter will not be correct.  The proper solution is shown on the board.

Deciding which fraction is larger can be hard.  Imagine a pizza cut up into equal slices.  The more slices there are, the smaller each slice will be.  Thinking like that can help you decide which fraction is bigger and which is smaller.  If the fractions are equal, you can find out by following the method on the bottom right of the board above.
