Grade 10 Mathematics — Lesson Plan

The learners should have knowledge and understanding of: the laws of sines and the laws of cosines; translations, reflections, and rotations, in the Cartesian plane; quadratic inequalities in one variable and in two variables; absolute value equations and inequalities in one variable and their graphs; box-and-whisker plots, and cumulative frequency histograms and polygons; quartiles, deciles, and percentiles; interquartile range, and outliers.

By the end of the term, the learners are able to: find sides and angles in oblique triangles using the laws of sines and the laws of cosines; describe translations, reflections, and rotations in the Cartesian plane; solve and graph the solutions of quadratic inequalities in one variable and in two variables; solve absolute value equations in one variable and absolute value inequalities in one variable, and graph the solutions; construct and interpret box-and-whisker plots, and cumulative frequency histograms and polygons; calculate quartiles, deciles, and percentiles; interquartile range, and outliers.
