<p>I updated original Numicon Shapes. We dont need base board. The parts are stack on top of each other. Numicon Shapes are so clever and very helpful in teach mathematic! They are incredibly versatile, and they help children see numbers as concrete concepts. Numicon Shapes are flat plastic shapes with holes in, representing numbers 1 through 10. The Numicon Shapes can also be differentiated by colour.</p><h4><strong>Printing instructions for boxes and grids:</strong></h4><ul><li>filament PLA</li><li>0,2 mm layer height</li><li>no supports</li><li>infill 30%</li><li>grid infill</li></ul><p>Commercial examples at: <a href="http://www.numicon.com/">http://www.numicon.com/</a></p><p>Free to download activities at:<br>Oxford University Press <a href="https://global.oup.com/education/content/primary/teaching-support/pages/numicon1/?region=international">https://global.oup.com/education/content/primary/teaching-support/pages/numicon1/?region=international</a></p>
