Grade 9 Mathematics — Lesson Plan

The learners should have knowledge and understanding of: simple geometric concepts and notations; perpendicular and parallel lines, and angles formed by parallel lines cut by a transversal; relations and functions; graphs of linear functions, and the identification of domain and range, slope, intercepts, and zeros; parallelism and perpendicularity of lines; different quadrilaterals and their properties.

By the end of the term, the learners are able to: illustrate and describe points, lines, rays, line segments, angles, and planes; construct perpendicular and parallel lines; determine the measure of the angles formed by parallel lines cut by a transversal; identify relations and functions; graph a linear function and identify the domain and range, intercepts, slope, and zeros; determine the conditions for lines to be parallel or perpendicular; use geometric properties to find unknown sides and angles of quadrilaterals.
