Writing instrument that calculates grade

1. A method for facilitating grading, comprising

(a) receiving, at a writing instrument, an identification of a total number of available points input using one or more data entry devices of the writing instrument;

(b) thereafter,

(i) receiving, at the writing instrument, a first set of one or more indications, input using one or more data entry devices of the writing instrument, to subtract a point,

(ii) calculating, via a processing device of the writing instrument after each indication to subtract a point of the first set of one or more indications is received, a grade using division based on the identified total number of available points and the number of indications of the first set of one or more indications, and

(iii) displaying, after each calculation following receipt of an indication to subtract a point of the first set of one or more indications, the grade calculated by that calculation;

(c) thereafter, receiving, at the writing instrument, an indication to reset input using one or more data entry devices of the writing instrument;

(d) after receiving the indication to reset,

(i) receiving, at the writing instrument, a second set of one or more indications, input using one or more data entry devices of the writing instrument, to subtract a point, and

(ii) calculating, via a processing device of the writing instrument after each indication to subtract a point of the second set of one or more indications is received, a grade using division based on the identified total number of available points and the number of indications of the second set of one or more indications, and

(iii) displaying, after each calculation following receipt of an indication to subtract a point of the second set of one or more indications, the grade calculated by that calculation.

2. A writing instrument for use by a grader, comprising:

(a) an elongate, tubular housing;

(b) a writing component secured within the housing and operative to make marks on a surface; and

(c) a calculation assembly comprised of electronic components, the calculation assembly being retained within the housing and including,

(i) a plurality of data entry devices for entering data used to calculate a grade, the data entry devices being accessible by the grader through an exterior surface of the housing,

(ii) a processing device programmed to receive data from the plurality of data entry devices and calculate the grade based on the entered data by performing division, and

(iii) a display component for displaying to the grader the grade calculated by the processing device;

(d) wherein the calculation assembly is configured to allow a grader to identify, via one or more of the plurality of data entry devices, a total number of available points;

(e) wherein a particular one of the data entry devices is a point subtraction device, and the calculation assembly is configured to allow a grader to indicate, via actuation of the point subtraction device, that a point should be subtracted;

(f) wherein the point subtraction device is located proximate a tip end of the housing, and the writing instrument is configured to allow a grader holding the writing instrument in a hand to both

(i) write with the instrument, and

(ii) actuate the point subtraction device

without adjusting his or her grip on the writing instrument; and

(g) wherein the calculation assembly is configured to display, via the display component, a grade calculated based on the identified total number of available points, and the indicated number of subtracted points.

3. The writing instrument of claim 2 , wherein the point subtraction device is located proximate a tip end of the housing such that a grader holding the writing instrument in a hand for making a mark on a surface can actuate the point subtraction device with a finger of that hand.

4. The writing instrument of claim 2 , wherein at least one of the data entry devices is configured to allow a grader to add back a point that was previously subtracted.
