In Geometry class of VI grade students, the teacher explained the construction of angles measuring 30°, 60° and 90°, with the help of demonstration of construction and bisector of an angle. Then, she asked the students to construct an angle of 15° and an angle of 45°. This task at this point reflects the teacher's intention to

• assess the learner's performance in summative assessment

• give the exposure of experiential learning

• assess the student's understanding and ability to combine two skills learnt, to accomplish the given task

• engage every student in some work
