That combination reaches any whole number of grams up to 300 in a sensible way, which is what makes a weight set useful rather than just heavy.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eColour coded by denomination\u003c\/strong\u003e, so a child picks the right one by sight instead of reading a stamp. That is the difference between a maths lesson about mass and a maths lesson about finding weights.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHexagonal and stackable.\u003c\/strong\u003e Hexagons do not roll off a bench, and they stack neatly on a balance pan without sliding. At 35mm across they are big enough for small hands.\u003c\/p\u003e\u003cp\u003ePlastic rather than brass or iron - lighter to carry as a class set, no rust, no sharp edges, and cheap enough to lose a few. For hanging masses in physics, buy the slotted iron weights instead.\u003c\/p\u003e","brand":"Educational Vantage","offers":[{"title":"Default Title","offer_id":53793066320235,"sku":"EVNK1109","price":19.5,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0963\/2795\/8891\/files\/nk1109_plastic-weights-35mm-hexagonal-8211-set-of-54-pieces.webp?v=1788358357","url":"https:\/\/megaofficesupplies.com.au\/products\/plastic-hexagonal-weights-set-of-54","provider":"Mega Office Supplies","version":"1.0","type":"link"}
