Rounding Money 100 Square

On the day on which rounding money comes into operation in Ireland, this resource may assist pupils in calculating whether to round up or round down. It consists of a colour-coded 100 square – one colour showing when to round down (1c, 2c, 6c, 7c); one colour showing when to round up (3c, 4c, 8c, 9c); and one colour showing the nearest 5c. It would also be good to be shown large on an IWB as a visual prompt when doing work on rounding.
