Document Summary
Number sense refers to an intuitive feel for numbers (mcintosh, 1997) good number sense is essential for the development of efficient computation strategies. Requires an understanding of number concepts & operations, developing useful and flexible strategies for handling these, the facility to compute accurately and efficiently to detect errors, and recognise results as reasonable. Classroom implications: a structured daily focus on mental computation can build fluency with basic facts and number sense. Ensure students are aware of the difference between mental computation and estimation. Cardinal number: refers to a quantity (how many squares) ordinal number: refers to a placing or ranking (1st, 2nd, 3rd) nominal numbers: used as labels (postcodes, mobile numbers).
