8th Grade Math Curriculum
8th grade math curriculum will teach students topics which they have already learnt in 7th grade math but in details and some topics are new. Such as radical, factorization, variation, construction of quadrilaterals, area of trapezoid, 3D shapes such as cube, rectangular prism(cuboid) and cylinder. In 8th grade math student will learn about the graphs. How to plot the points on the graph, reading off from the graphs, reading of the linear and reading of distance time graph.
