Learning Objectives
What are the students expected to understand/ learn from this topic. These can drive from the large concept map and should be listed at the concept level.
Teaching Outlines
Concept 1: Angles
Briefly describe the concept (2-3 sentences)
Activities
Introducing formation of angle
Types of angles
Concept 2: Pairs of angles
Activities
Adjacent angles
Complementary angles
Supplementary angles
Vertically opposite angles
Linear pair axiom : If a ray stands on a line, then the sum of two adjacent angles so formed is 180o
Linear pair axiom : If the sum of two adjacent angles is 180o, then the non-common arms of the angles form a line
Concept 3: Parallel lines
Activities
Introducing parallel lines
Angles associated with parallel lines
Parallel lines and measures of angles formed
Solved problems/ key questions (earlier was hints for problems).
(This will be directly correlated to the textbook so that teacher gets what they may be looking for but we must have additional questions which are sourced from other resources)
Projects (can include math lab/ science lab/ language lab)
Assessments - question banks, formative assessment activities and summative assessment activities
Categories will be: (Subject), (Topic), (Class 8), (Class 9), (Class 9), (Concept Map), (Question banks), (Assessments), Formative, Summative
