FOREWORD

The following Grade 10, 11 and 12 Lesson Plans were developed by Subject Advisors from 09 March – 13 March 2009. Teachers
are requested to look at them, modify them where necessary to suit their contexts and resources. It must be remembered that
Lesson Plans are working documents, and any comments to improve the lesson plans in this document will be appreciated.
Teachers are urged to use this document with the following departmental policy documents: Subject Statement; LPG 2008; SAG
2008; Examination Guidelines 2009 and Provincial CASS Policy/ Guidelines.
Lesson planning is the duty of each and every individual teacher but it helps when teachers sometimes plan together as a group.
This interaction not only helps teachers to understand how to apply the Learning Outcomes (LOs) and Assessment Standards
(ASs) but also builds up the confidence of the teachers in handling the content using new teaching strategies.
It must please be noted that in order to help teachers who teach across grades and subjects, an attempt has been made to
standardise lesson plan templates and thus the new template might not resemble the templates used in each subject during the
NCS training. However, all the essential elements of a lesson plan have been retained. This change has been made to assist
teachers and lighten their administrative load.
Please note that these lesson plans are to be used only as a guide to complete the requirements of the Curriculum Statements and
the work schedules and teachers are encouraged to develop their own learner activities to supplement and/or substitute some of
the activities given here (depending on the school environment, number and type of learners in your class, the resources available
to your learners, etc).
Do not forget to build in the tasks for the Programme of Assessment into your Lesson Plans.
Strengthen your efforts by supporting each other in clusters and share ideas. Good Luck with your endeavors to improve Teaching,
Learning and Assessment.
