PREFACE At what precise age a child should begin to gc to schoal, or commence the different studies, it is not our province to I decide. Whatever may be the diversity of opinion on I this point, all practical teachers seem to agree, that Men- \ id A^thmetic is among the first exercises which should j be presented to the youthful mind. The correctness of I this sentiment is corroborated by the ease with which I children understand simple combinations of numbers, their ! fondness for the!>e exercises, and the obvious advantages I which may be derived from them. But in order to be- I come interesting or profitable, it is manifest, this branch, j as well as others, must be taught in such a manner that the pupil shall understand it. The examples, therefore, j must, at first, be simple, containing small numbers, and have reference to sensible objects with which the learner is accjuainted ; the transition from easy to more difficult (questions must be gradual; and the reason for every step in the solution distinctly seen. It is believed that much dislike for the study of Arith- metic, and much unnecessary discourage7nent, have been occasioned by the abruptness of the transitions from easy to difficult questions. It is too often forgotten that the powers of the child's mind, Lke those of his body, are feeble ; that while familiar mental exercises which he can comprehend, afford him the highest delight, he turns from intricate questions, which he does not and cannot under- itand, with indifference and disgust. It is the design of this little work to furnish a ser^^ of mental exercises in numbers, adapted to the wants and cnparities^of children. It commences with practical ex- amples, which relate to familiar objects and require the PREFACE. simplest combinations. The pupil is then introduced to others involving the same principle but somewhat harder, special care being taken to make the transition very grad- ual, so that instead of being disheartened at the rugged- ness of the way, he shall be stimulated to take the next step by the hope of victory. From the fact that children comprehend and remember words more easily than figures, and reason upon them with so much greater facility, the numbers and Tables in the first part of the book are expressed in words. After the pupil has become practically acquainted with the principles of a rule, and is able to solve questions un- der it with facility, the operation is then defined, and the more prominent terms are briefly explained. This, it is believed, teachers will be glad to see. There is no rea- son why a child should not be informed, that a certain operation upon numbers is called Addition ; another Sub- traction ; &c., as well as to be told that a certain opera- tion of his vocal organs in connection with those of his mind, is called reading ; another singing ; &c. With this brief explanation of the object and plan of the work, the author commends it to the friends of edu- cation, by whom his former efforts to subserve this noble cause, have been so favorably received. Although designed particularly as an introduction to the *' Practical Arithmetic," it may be used as a prepar- atory work to any of the larger systems of Arithmetic now aefore the public. MENTAL ARITHMETIC. SECTION I INTRODUCTION, The first step in acquiring a knowledge of numbers is to learn to count. Most children are able to repeat the na7}ies of numbers, one, two, three, (Sec, before they begin to go to school ; but there are fewer who fully comprehend the meaning of these terms; who perceive, for example, that eleven expresses more things than seven, or fewer than thirteen. While such is the case, no substantial progress can be made in Arithmetic. Great pains should therefore be taken to show young pupils, in the outset, how many things thf» name of each number denotes, and to establish in their minds a correct idea of more and less. Counters, made of round pieces of wood or leather, also beans, kernels of com, &c., may be used for this purpose ; but the most convenient appa- ratus is the Numerical Frame.* The bails upon the wires are more easily arranged and are seen at once by every member of the class, while the liability of falling upon the floor and getting lost, is entirely avoided. LESSON I. Having slipped all the balls to the left side, the teacher holds up the Numerical Frame before the class and requests their particular attention. • Every instniclor who is called upon to tearh the nidimfntfl of Arithmetic, should be furniBhed wiih this useful instrument, it INTRODUCTION. With his pointer he now moves the first ball on the bottom wire to the right side and says, this is oiie, the class repeating it with him. Moving across another on the same wire, he says, this makes two, the class repeating it with him as before ; moving an )ther, this makes three ; another still, this makes ' four ; and yet another, this makes Jive ; and so on up to ten. Tliis process should be repeated and varied ac- cording to circumstances, u.itil the class can count ten in concert and individually with readiness. If this cannot be accomplished in one exercise, another should be devoted to it. Note.—U the (hilach, if the teacher always begins at the same end of the cla^^ and proceeds through it iii regular rotation. 10 ADDITION, 9. I^ I move out six on the lower wire and one on the next, how many will they make ? Why ? 10. If I move out seven on the lower and one on the next, how many will they make ? Why ? 11. If I move out eight on the lower and one on the next, how many will they make ? 12. If I move out wne on the lower and one on the next, how many wi 1 they make ? Note. — A« loon m a child learns a principle in Arithmetic, it i« iniportajit for him to see ita application, ana begin to practice it. For this reason, it js recommended to let the class iludy the next eight lessons in connection with the corresponding paru of the Ta- ble be.ow. Thus, as soon as they learn to add twos, let them take lesson second yvhich contains exercises in adding two ; as soon as they learn to add threes, let them take lesson third, &c. In this way the Table is kept together, which is essential for reference ana review, ar.d at the same time we secure all the advantages of studying it jx connection with examples which put it into prac- tice, as fast as it is leamexi.

Thus, to show that five and four make nine, mi-ve out five balls on one wire and four on another, and let the pupil count them together. But as I soon as the pupil understands the principle of the oiHiration, he should tlien learn to i»crforra it without the assistance of visible objects. Nothing is more deleterious to mental growth and dis- cipline, than the habit of solving questions by counters, by the fingers, marks upon a slate, &c. (S^n.

Note. — To iUiistrate ttiis point, move out four balls on the lower wire, and four apiece on the seroinl and third wires. This will denote three times four, or four added to itself three times, which the pupil will perceive make twelve. Again, letting these remain in their present place, move out three balls on the upper wire, also three apieiece : how many brothers had he ? Suggestion. — Since he gave two maibles to each, he manifestly had as many brothers, as two marbles \ * are contained times in ten marbles. Note.—'^\\Q principle of dividing may be illustrated in the fol- lowinsr manner : Pass acrosR ten balls on one of the wires, which may represent the ten marbles. Now since he gave two marbles to each brother, moving: out two balls will denote one brother; movinor out two more will denote another share, and so on, every two I alls will denote one brother, till all the balls are removed or exliai ?ted. Finally, counting the number of twos or pair of l5;dls moved out, it will sliow how many times two marbles are con- tained in ten marbles, which is the number of brothers he had. DIVISION. 57 5.

TROY WEIGHT. IV. Troy Weight is used in weighing gold, sil- ver, jewels, liquors, tfec, and is generally adopt(?d in philosophical experiments. 24 grains {i(r.) make 1 pennyweight, markud jnt^t, 20 pennyweights " 1 ounce, " oz. 12 ounces " 1 pound, " lb. Note. — Most children have very erroneous or indistinct ideas of the weiirhts and measures in common use. It is, therefore, strongly recommended for teachers to illustrate them practi- cally, by referring to some visible object of equal magnitude, or by exhibiting the ounce, the pound ; the linear inch, foot, yard, and rod ; also a sqitare and cubic inch, foot, Slc. AVOIRDUPOIS WEIGHT. V. Avoirdupois Weight is used in weighing gro- ceries and all coarse articles ; as sugar, tea, coffee, butter, cheese, liour, hay, «fec., and all metals except gold and silver.

Time is naturally divided into days end years ; tiie former are caused by the revolution of the Earth on ite axis, the latter by its revolution round the Sun. 60 seconds {see.) 60 minutes 24 hours 7 days 1 weeks 12 calendar months, or / 365 days, 6 hrs., (nearly,) ) 13 lunar months, 1 day, and 6 hours (nearly), make 1 year. Obs. 1. Time is measured by clocks, watches, chronometers, dials, hour-glasses, Ac. 2. A civil year is a legal or common year , a period of time es- tablished by government for civil or common purposes. 3. A solar year is the exact time in which the earth revolves round the sun, and contains 365 days, 5 hrs. 48 min., and 48 sec. 4. A Bissextile, or Leap year, is a year which contaixis 366 days, and occurs once in, /our years. It is caused by the excosa of 6 hours, which the civil year con- tains above 365 days, and is so called because it leaps or runs over one day more than a common year. The odd day is added to February, because it is the shortest month. Every leap year, therefore, February has 29 days. XV. The names of the days of the week are the following : Sunday, (first day,) Monday, (csecond,) Tuesday, (third,) Wednesday, (fourth,) Thursday, (fifth,) Friday, (sixth,) Saturday, (seventh.) Obs. The names of the days of the week are derived from the names of certain Saxon deities or objects of worship. Thus, Sunday is named from the sun, because this day was dedicated ! to its worship.
