{"product_id":"montessori-brown-stair","title":"Montessori Brown Stair","description":"\u003cp\u003eThe Montessori Brown Stair is a classic sensorial material that introduces children to the concept of thickness through hands-on comparison. Ten dark brown wooden prisms, identical in length but grading in thickness from 0.7 cm to 7 cm, are arranged from thinnest to thickest to build a stair. Children develop visual discrimination, order, and early mathematical thinking through this simple, beautiful work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e10 solid wood prisms grading from 0.7 cm to 7 cm in thickness\u003c\/li\u003e\n\u003cli\u003eAll prisms are equal in length at 14 cm\u003c\/li\u003e\n\u003cli\u003eDark brown finish, smooth and safe for handling\u003c\/li\u003e\n\u003cli\u003eCE certified\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eEducational Benefits\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eVisual discrimination of thickness and dimension\u003c\/li\u003e\n\u003cli\u003eSeriation and ordering skills\u003c\/li\u003e\n\u003cli\u003ePreparation for early math and measurement concepts\u003c\/li\u003e\n\u003cli\u003eConcentration and independent sensorial work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eWays to Play\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eArrange prisms from thinnest to thickest to build the stair\u003c\/li\u003e\n\u003cli\u003eClose eyes and order by touch alone\u003c\/li\u003e\n\u003cli\u003eCombine with the Pink Tower for extended sensorial work\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Oliver \u0026 Company Montessori Toys","offers":[{"title":"Small Size","offer_id":52318951571757,"sku":"32814103037-Small Size","price":60.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0702\/2601\/8605\/files\/HTB12TfARXXXXXb.aFXXq6xXFXXX6.webp?v=1787690199","url":"https:\/\/olivermontessori.com\/products\/montessori-brown-stair","provider":"Oliver \u0026 Company Montessori Toys","version":"1.0","type":"link"}
