Blackboard   Listen
noun
Blackboard  n.  A broad board painted black, or any black surface on which writing, drawing, or the working of mathematical problems can be done with chalk or crayons. It is much used in schools. In late 20th century similar boards of a green slate as well as some colored white became common; wrioting on the slate bioards may be done with chalk, but writing on the white boards is done with colored pens, such as grease pens, which leaves a trace that can be easily erased. The newer boards, usualy called chalkboards are nevertheless still sometimes referred to as blackboards.

"Blackboard" Quotes from Famous Books



... was quite gone, and the blackboard erasers, the bits of crayon, and the pointer had been thrown after them, the Prince put his hands in his pockets and lounged to the window, whistling a tune he had caught from a hand-organ. His twelve younger sisters were just coming into the courtyard, two by two, returning from taking ...

... first-class carriage next to a gentleman who travels for a great claret and champagne house, and opposite another going down express to report a railway meeting at Birmingham for a morning paper. If you see a lady carefully and courteously escorted to a carriage marked "engaged," on a blackboard, it is probably not a countess but the wife of one of the principal officers of the company. A bishop in a greatcoat creates no sensation; but a tremendous rush of porters and superintendents towards one carriage, announces that a director or well-known engineer is about to take ...

... for simple words and simple constructions. "He that runs may read" him. I have found many children under eleven years of age who could read a whole page without hesitating. If I discover some words which I foresee will cause difficulty, I place such on the blackboard and rapidly pronounce and explain them before the reading. Generally, however, I find the text the best interpreter of its words. What follows explains what goes before, if the child is led to read on to the end of the sentence. It is a mistake to allow children to be frightened away from choice ...

... quite as well as the other girls in most things, and was beginning to congratulate herself upon knowing as much as any one of her age, when she was called to the blackboard to write out a sentence. At her feeble effort which resulted in a crooked scrawl, there was a subdued titter from the others. For one moment the new scholar stood, her cheeks flaming, then with defiant face she turned to Miss Dorothy. "I can spell it every word," ...

... prevention of pain should be explained. Under the hygiene of the period, the daily bath should be urged, with caution against chills, in which lies the only possibility of injury. The fertilization of the ovum and cell division may be described by use of the blackboard and embryological models of the later stages of development. The forces which bring about labor can be explained without unduly stressing ...

... preparing the reply to Matt Peasley's cablegram, and dictating for Cappy Ricks' signature a letter to Noah Kendall's widow, Cappy was busy at the telephone. First he retailed the news to the Merchants' Exchange, to be bulletined on the blackboard and read by Captain Noah's friends; next he called up the secretary of the American Shipmasters' Association, of which the deceased had been a member, and lastly he communicated the sad tidings to the water-front reporters of all the daily papers. This detail attended to, Cappy's active ...

... the West. Being very impressionable, he imbibed a great deal which he has turned to good account in his chosen work. At fourteen he started to carve figures from the chalk that conventionality required to be used on blackboard problems. At eighteen he entered the Chicago Art Institute, where he stayed for but three months. He soon went to Paris, going first to the Beaux Arts and later to the Colorossi and Julian Academies. He won many honors during his three years stay in Paris. ...

... immanent in truth. If I ask myself why bodies or minds exist rather than nothing, I find no answer; but that a logical principle, such as AA, should have the power of creating itself, triumphing over the nought throughout eternity, seems to me natural. A circle drawn with chalk on a blackboard is a thing which needs explanation: this entirely physical existence has not by itself wherewith to vanquish non-existence. But the "logical essence" of the circle, that is to say, the possibility of drawing it according to a certain ...

... wit, to relieve the tedium of the daily lesson with a species of round game which was played as follows. As soon as the master had taken his seat, one of the players would execute a manoeuvre calculated to draw attention on himself, such as dropping a book or upsetting the blackboard. Called up to the desk to give explanation, he would embark on an eloquent speech for the defence. This was the cue for the next player to begin. His part consisted in making his way to the desk and testifying to the moral excellence of his companion, and giving in full the reasons why ...

... grotesquely expressive mouth, which displayed every one of a splendid set of teeth. He had small, short-sighted, red-rimmed eyes, and curly hair which did not stop growing at his ears, but went on curling, closely cropped, down the sides of his face. He taught at the top of his voice, thumped the blackboard with a pointer, was biting at the expense of a pupil who confused the angle BFC with the angle BFG, a moment later to volley forth a broad Irish joke which convulsed the class. He bewitched Laura; she forgot her sums in the delight of watching ...

... Mucius Scaevola and Junius Brutus? Are all the characters graven so deeply by the stylus of Clio upon so many monumental tablets, and almost as indelibly and quite as painfully upon school-boy memory, to be sponged out at a blow, like chalk from a blackboard? We, at least, cling fondly to our Tarquins; we shudder when the abyss of historic incredulity swallows up the familiar form of Mettus Curtius; we refuse to be weaned from the she-wolf of Romulus.

... And why? Was it because in the first short twelve months of his career he sold, delivered, and got the money for, 5107 copies of 'Mend-me-at-Home'? No. Was it, then, because three years later he sold in one year, with no other assistance than a man to drive the horse and wagon, hold the blackboard, and hand out the books, 10,003 copies of 'Rapid 'Rithmetic'? It was not. Was it, then, because in 1878, reading aright the public mind, he said to his publishers, whose confidence in him was unbounded, 'It ...

To get an idea into his mind requires a blackboard and Chautauqua lecturer, but once he masters it, he never lets go; so it will be with football signals, once let him grasp a play, he will never be confused. He is simply a huge, stolid giant. He has a bulldog purpose to get an education, and nothing ...

The room was large, and but for the lighted gas, burning crudely without globes, would have been dark. All one wall opposite the door was taken up by a great blackboard covered with chalked figures in columns, and illuminated by a row of overhead gas jets burning under a tin reflector.

There were marks the friends made on things to talk about, and on things not to, and one of the latter in particular fell like the tap of chalk on the blackboard. Married at thirty, Waymarsh had not lived with his wife for fifteen years, and it came up vividly between them in the glare of the gas that Strether wasn't to ask about her.
