TOPICS/CONTENTS 4 – ANGLES & TRIANGLES

5B (8.00 – 9.00 am) B – Sum of angles in a triangle

OBJECTIVES At the end of the lesson pupils will be able to;

a) recognise that the sum of angles in a triangle is 180° b) Manipulate simple drawing using a photo editing software.

REMARKS 5B

MONDAY : 16TH MARCH 2009 PRESENTATIONS 1. Introduction; (15 min) Teacher recalls back previous lesson, by asking pupils what they have learnt throughout the topics this particular topic. Example:i) What is the angle on a straight line? ii) What is the angle at a point?, etc. 2. Lesson Activities; (40 min) Individual activity:Teacher will move on a new sub-topic which is sum of angles in a triangle. Pupils will soon learn that the 3 angles of a triangle add up to 180°. To demonstrate, teacher will be take a blank sheet of paper, in which the teacher will cut out a triangle out of it. - Teacher will give instructions on what he will do. (Teacher refers to textbook, Page 55). a) cut-out a triangle b) cut in into 3 pieces c) arrange - Based on the arrangements teacher have make, they will observe that the 3 angles of the triangles are angles on a straight line. ( ∠a + ∠b + ∠c = 180°) - Teacher will then continue by giving several examples by using a simple photo editing software on how to manipulate drawings. - Pupils will draw a triangle and cut it into three pieces and then will arrange the pieces to show a straight line. 3. Conclusion (15 min): Teacher summarises the lesson.

ASSIGNMENT Practical Work: -Pupils will draw a triangle - cut it into three pieces - arrange the pieces to show a straight line.
