This is a remix of the Zahlenstrahl Puzzle: https://tactiles.eu/3d-model/zahlenstrahl-puzzle-number-line/
Changes I’ve made:
- Added a place for a label on the left end (e.g so you can have a 0)
- Optional place for labels in the middle of a segment
- Braille label pieces that can be attached using blu-tack
- Counting in 3s, 4s, 5s and 6s pieces. These have vertical UEB labels, + on one side, – on the other, with tactile markers on the top to aid with counting
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 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. Use the counting pieces to skip count across the number line.
