Estimation for Numeracy. Numeracy Project.
A program for teaching "number sense" is suggested based on experiences in teaching numeracy to Papua New Guinean adults. Number sense starts out with some sort of "feel" about the size of a number and extends upwards to include any such mental arithmetical skills as can reasonably be incorporated in an appropriate program. What number sense does not include is anything requiring paper/pencil or a calculator. With the exclusion of problem-solving, the major part of number sense consists of the ability to estimate or the ability to obtain approximate answers for problems already stated in numerical terms (arithmetic estimation). Appropriate methods of estimating the total of a column of numbers and the difference and mean of any two numbers are suggested. In addition, methods for multiplication and division are suggested. In order to compare different methods of estimating related to these mathematical processes, a computer program written for the Sinclair ZX Spectrum microputer was employed. Notes on the program and complete program listing are included. (JN)
