Year 5 have been investigating square and cube numbers. Using counters to investigate square numbers they found which numbers it was possible to make a complete square with. They found that 1, 4, 9, 16, 25,36,49 are square numbers up to 50. They soon realised that if you multiply a whole number by itself you get a square number.
In another lesson they carried out an investigation with cubes to find out which numbers are cube numbers. They found that 1, 8, 27, 64 are cube numbers up to 100. They discovered that in order to find a cube number you have to multiple the number by itself then by itself again.
