[Nfb-krafters-korner] {Disarmed} OT: anyone remember those old math slates from the sixties? here's an article about them.

Hi Cathy,

While I do not remember this particular math slate, we used one called a "cube slate". It was made of rubber or some type of plastic and was comprised of square openings.  There were plastic cubes with dot configurations to represent the numbers 0-9.  You would manipulate the cube until it represented the dot configuration of the number you wanted 

Thanks for sharing and for the trip down memory lane.

Hi all,

I promise not to send forwards like this all of the time. but I know there are many of you who attended schools for the blind as I did in the sixties. So I thought you might find this interesting.  

Btw, if you find these article interesting you might wish to subscribe to the newsletter on aph.org.

Have a great day!!

Recently one of our followers on Twitter asked us about the Taylor Slate so we decided to feature it in this column. The first photo shows the slate, itself, with this description: “The aluminum Taylor Slate has an 18 x 24 grid of star-shaped holes and a tray to hold types.” The second photo shows a key to represent how rotating the types lets you represent all ten digits and the operatives. The full description is below. The description from Museum Director Micheal Hudson is below.
The Reverend William Taylor became superintendent of the Yorkshire School for the Blind in England in 1836.  While at the school he developed his "Ciphering Tablet,” and the design was eventually used in schools around the world.  A metal board is pierced by rows of star-shaped octagonal holes.  The board came with a stack of metal “types,” basically small rectangles with two raised pins on one side and a raised bar on the other.  By rotating the types in the octagonal holes, each type could assume enough different shapes to represent all the numbers and the operator symbols.  Other inventors had developed boards that used types with raised numbers on top.  Since each piece of Taylor’s type could be used to represent all ten numbers and the operatives, there was less time wasted searching for a particular number.  APH introduced its own Taylor Slate in 1938/1939, made from stainless steel. By 1953, the type was available in both lead and plastic.  The product was discontinued by 1972.  BUT…  you can still buy one, amazingly enough.  A company in India,  <http://aph.us8.list-manage.com/track/click?u=0d9bb2b66f092e599244d8765&id=6901ea20e6&e=b0cc85e67d> Advance Engineering makes a lot of the older devices for the third world market.
