The Fraction Stack provides opportunities for students to work with fractions. Each piece has braille on one side and indented print on the other, so it can be used by all students in the class. The height of the pieces change, relative to the height of the rods that represent one whole. There is an […]
This is a remix of the Zahlenstrahl Puzzle: https://tactual.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 […]
This is a set of 7 prints with the following quadrilaterals (4 sided shapes) Square Rectangle Rhombus Parallelogram Kite Trapezium Irregular quadrilateral Important features are marked on each shape tactually and can be drawn/painted to provide colour contrast Same length sides are shown with a dash (or two) Parallel lines are shown with an arrow […]
This set is an extension of a set created by one of our parents. It provides opportunities for practice with place value, including three decimal places. The labels for each place are shortenings for space reasons: th = thousands, h = hundreds, t = tens, ones = ones, tth = tenths, hth = hundredths, thth […]
This is a kit for modelling covalent bonding. Electrons are represented by spheres, in pairs. The nucleus is represented as a cylinder/circle in the middle of the model. The models can be attached like puzzle pieces, demonstrating the ‘sharing’ of electrons that occurs in a covalent bond. Add a braille and print label to the […]
This is a remixed scale model of the solar system with Braille labels on the vertical faces of the base. The planetary sizes are based on data from NASA. The curve at the back represents part of the Sun. There several versions of this print The model with scale factor 0.0003 (1mm = 3333 km) […]
These prints show several different properties of the elements. The height is used to give a sense of the trend over the whole periodic table, as such individual elements aren’t labelled. Periodic Table – density The height of the model represents the relative density of each element on the periodic table. All but two elements […]
Use this kit to experiment with ionic compounds. The cations have ‘studs’ on the right hand side of the print. The anions have ‘holes’ on the back of the left hand side of the print. The number of studs/holes corresponds with the charge on the ion. Match up the correct number of each cation and […]
This print comes in 2 versions, a purely tactile protractor, and a combination tactile and LP protractor. For the tactile protractor: The tactile ticks are every 5 degrees, with larger ticks at 0, 30, 60, 120, 150 and 180 degrees, long dashed line at 45 and 135 degrees and long solid line at 90 degrees. […]
Nets of common 3D shapes. Joints are hinged with interlocking teeth on other edges. There are multiple versions of the cube and square based pyramid to demonstrate that the same shape can be made from two very different nets. Also one ‘not’ net for each to show that not all combinations of those faces create […]
