Blackboard Protractor
Product Code : JL-LEP-10172
The Blackboard Protractor (SKU JL-LEP-10172) aids the teacher in constructing and drawing angles, arcs and circles on the board. Because it is made for whole-class demonstration, the blackboard protractor draws large, clearly visible figures, so students can see how an angle is measured and marked before they repeat it with their own protractors. It supports geometry lessons in primary and secondary schools. JaincoLab manufactures it in India as a mathematics teaching aid, made as per DepEd guidelines.
Specifications
The Blackboard Protractor is specified by its classroom role: it helps the teacher construct and draw angles, arcs and circles on the board, it draws them large and clearly visible, and it is made as per DepEd guidelines under SKU JL-LEP-10172.
