Adjustment made to number line pieces
Middle of number line label option added
Counting in 3s, 4s, 5s and 6s pieces added. These have verical braille labels, + on one side, - on the other, with tactile markers on the top to aid with counting
More braille label options added
This is a remix of the Zahlenstrahl Puzzle on Tactiles.eu https://tactiles.eu/3d-model/zahlenstrahl-puzzle-number-line/
I've added a spot for a label to the left end piece, along with various braille label pieces.
This number line is flexible in its use. Segments can be added in the middle to extend the number line. Braille labels can be added at the 'tenth' mark to make the number line represent a variety of situations: natural numbers, negative numbers, decimals, even large numbers. Pegs can be used to highlight a particular number/numbers.
Print the braille label pieces upright, so the braille is on the vertical face. Attach the braille label pieces with blu-tack to the numberline.
