June 7, 2015: Blackboards from 1917

Oklahoma City, December, 1917. Emerson High School's custodian, R. J. Scott, has taken delivery of brand-new slate blackboards to replace the old ones that are not in good condition. He writes on each room's old board that today is the day the new ones are going to be installed.

It's a pretty big deal.

But R.J. got lazy, faced with several rooms to work on over a week's time; and he decided to just mount the new boards right over the old boards.

And two days ago workers came to remove the chalkboards altogether; they're installing network cables in this building that was built in 1895 and has been the High School since then.

And when they removed the first layer of slate, they found those old blackboards from 1917, with the lessons still on them.

Over the years we teach kids how to do math in radically different ways. But here's your challenge: WTF is this? How does it work?

What a wonderful find! The lessons/boards seem surprisingly modern in tone

Nothing is ever new in education. Recycling at its best. I'm still trying to work out that math thing. Some kind of times table system... :)
Clodfobble • Jun 7, 2015 1:13 pm
I figured it was a puzzle of some type--cross multiply, or scratch out all the factors of whatever in order to reveal which numbers are left... If nothing else, there are no zeroes anywhere on it, so it can't be a stand alone system for anything.

It is a mighty fine circle though.

I doubt he got lazy. I think he probably left the boards as is on purpose, like a time capsule
xoxoxoBruce • Jun 8, 2015 10:59 am
Agree, not lazy. Why bother to take the old ones down, they weren't worth anything, couldn't be reused, and provided a flat stable surface for the new boards.

I'd say they got their money's worth from the slate boards.
But now no more sending the unruly out to beat erasers or using your fingernails to impress the girls.

The circle is a multiplication assignment with random numbers around the edge to match up with the ones in the middle.
I used one similar with my granddaughter to avoid the regimentation of the standard grid and introduce the randomness of actual use.
Something is to be learned in every pic.
The subjects covered were the end of Thanksgiving themes with a turkey and an unlikely African-American Pilgrim girl.
You can see the blobs of adhesive that Mr. Scott used to install the new boards as well as what might be the 1917 version of the Pledge of Allegiance.
Great IOTD

Nice analysis, DJ

I'm wondering if the hexagons above your multiplication circle are "shields of David" indicating a Jewish presence.

That is, there is a mention of the Dutch and moving to the Netherlands...
And wikipedia says the following:

Most history of the Jews in the Netherlands was generated between the end of the 16th century and World War II.
The area now known as the Netherlands was once part of the Spanish Empire but in 1581, the northern Dutch provinces declared independence. A principal motive was a wish to practice Protestant Christianity, then forbidden under Spanish rule, and so religious tolerance was effectively an important constitutional element of the newly independent state. This inevitably attracted the attention of Jews who were religiously oppressed in many parts of the world.

I like fonts, so... the cursive is identical to the cursive I was taught, how about you?

The non-cursive seen in the second-to-last image... is more difficult than "standard" alphabet, but probably matches what would have been the movable type fonts of the time. Someone copied that directly out of a book, including the serifs and what-not.

The curlie-ques on the numbers on the multiplication teaching tool are cute.

The Pilgrims went to Amsterdam to break with the Church of England, but after ten years they worried their children were becoming too Dutch, so they went back to England with the intention of sailing to New York. Absolutely nothing to do with Jews.
Shields of David? No, they're stars, something teachers have used since the invention of blackboards. I had teachers use them all through school. Do you think the Jewish kids had to wear armbands too? :rolleyes:

Stars !!! Look closer...
Stars always have and have had 5 points, not 6 :facepalm:

Geez, some people still believe Pluto is a planet :p:

well, they're certainly not hexagons

Wrong... again. Image

The symbol is more commonly known as the Star of David than as the Shield of David.

Did board compasses go out of fashion between 1917 and when you were at school?
Clodfobble • Jun 9, 2015 8:57 am
I can imagine what one is, but I never saw a teacher use one during my school career... I did have several teachers that used five evenly-spaced chalk holders for drawing musical staff lines, though.

My H.S. geometry teacher used a board compass all the time.

NOTE: No wheel caps were stolen during this google-cize&#8230;

My original thought related to a &#8220;Jewish presence&#8221; in Emerson High School in 1917,
so I looked for locations and histories of synagogues in Oklahoma City

Emanuel Synagogue located at Reno and Dewey streets
was &#8220;&#8230;at the center of the city&#8217;s Jewish community&#8230;&#8221; in 1917

[ATTACH]52005[/ATTACH]


Temple B&#8217;Nai Isreal membership was located at 50 N Broadway Circle was
&#8220;by 1925 &#8230; over 160 families&#8230;overcrowded&#8221;

[ATTACH]52006[/ATTACH]

Both synagogues were within 15 minutes walking time of Emerson High School.

[Google Map search for Emerson High School points to Emerson Middle School]

Coincidences ??? Sure, but not impossible

Good work and this is how we learn when we quibble.

I had almost posted "Surely there were no Jews in Oklahoma City in 1917...!" but there they were.
xoxoxoBruce • Jun 9, 2015 1:40 pm
There were Jews in the colonies, a Philadelphia Jew financed the American revolution, there were Jews in all the states, So what? Show me where they counted them, pointed them out, and tallied them on the school blackboard, in any American public school... ever. The notion is preposterous.

/\ This was my experience. /\

In fact the board monitor for the week, who usually only got to use the eraser (although spanking it outside was fun) and check there was enough chalk available, was always highly gratified if called up to prepare a chalk circle during a lesson.

I remember being sick with jealousy when we started to learn about Venn diagrams after I was board monitor. I never forgave Mirella C for that. Well, okay, I did. But it rankled for a long time.
