If in doubt about weights and unable to see samples, order medium weights or numbers.

Boards should be ordered in full bundles if possible. Note the varied classifications of quantities in bundles, and specify very carefully.

Calculations For Stock

In order to determine what amounts of paper stock to order for a school system, the following method will be found satisfactory:

(1) Find the enrolment per grade for the first four grades of the entire system. The enrolment for a given year may be taken roughly for that of the following year if orders are to be placed before the enrolment is known.

(2) Find the amount of 9"x 12" stock of each kind per pupil per grade. This may be taken from the bottom of tables on pages 161, 162, 163, and 164, or may be worked out from the listed amounts accompanying the directions in chapters II, III, IV, and V.

(3) Multiply the amounts of stock per pupil for each grade by the number of pupils in each grade, and add from ten per cent to twenty-five per cent extra for new pupils who may enter later, for spoiled work, for extra problems, and for other exigencies.

(4) Find how many 9"x 12" pieces can be cut from the large sheets and divide the totals in (3), above, by this amount to get the number of full sheets.

(5) Add enough to make up full ream lots of each style and weight if possible. If not, add enough to make up quarter or half reams. If this be impossible, any number of sheets may be ordered, but at an advance in price. The extra stock will help in starting the next year and should be deducted from the next year's order. School money should not be tied up unnecessarily in extra stock.

(6) Check calculations for gross errors. An example of the calculation for the first grade is as follows:

Medium tag board 1 piece (from list at bottom of page 161) times 150 (pupils) equals 150 (pieces); divide by 5 (the number of pieces per sheet) and get Suppose we get also

30 (full sheets in first grade)

00 (full sheets in second grade)

60 (full sheets in third grade)

325 (full sheets in fourth grade)

Add to make ream 415 sheets in all 85 sheets extra

Total medium tag board 500 sheets (or 1 ream, no pounds)

Other Supplies Needed

In the same manner we may add each item and make up a full order for paper for the entire school year. Miscellaneous small supplies such as stay tape, eyelets, thread, silk cord, paste, and glue are easily figured out. A pint of paste and a pint of glue should make up an average requirement for each class room, altho the work in the fourth grade demands more than the first, and more will be wasted in some rooms than in others. An extra supply should be kept in the supervisor's store room.

Sources Of Supply

As far as possible it is desirable to purchase from local dealers but much of the material needed is special in character and must be gotten from special dealers. Certain dealers make a specialty of supplies for primary schools and the largest of these can supply most of the equipment and supplies listed here. These larger supply houses are located in such cities as Boston, New York, and Chicago, with branches in other cities. Most city superintendents have their catalogs. Other special houses carry papers, book binders' material, or printers' supplies.
