The term 'blackboards' can be solved by the six-letter word 'SLATES'. SLATES are a type of flat stone, usually composed of shale, that has been used for centuries as a writing surface. In the 19th century, SLATES were replaced by blackboards, which are made of a smooth, dark material such as porcelain enamel or a mixture of gypsum and clay. Blackboards are still commonly used in classrooms today.
