Today we revised lots of different kinds of maths. We looked carefully at the parts we found hardest. The board above shows a question about area and perimeter. Area is the number of squares that fit into a shape. Perimeter is the distance around the outside of the shape. To find the perimeter, imagine you are a tiny ant. Start at one corner and crawl all the way around the edge until you get back to the corner where you started.
Adding decimal numbers is easy if you get the columns right. The decimal points must all be in line.
If you have to compare lengths, first change them all into centimetres. It will then be easy to see which is the smallest, and the next, and so on.
Over the next few days we will do lots more maths revision.
