61 SUBJECT Mathematics TOPIC FROM CURRICULUM GENERAL TOPIC: SUBTOPIC GEOMETRY AND MEASUREMENT Geometric elements LEARNING OBJECTIVES Different types of angles: concave / convex, solid angle, zero angle, elongated angle, sharp angle, obtuse angle, right angle, draw angles and describe the size of individual types of angles. ART EXPRESSIOSIONS/VISUAL FORMS USED Drawing / constructing a right angle with the help of a string. SPECIAL REQUIREMENTS Rope, sticks. MOTIVATIONAL STAGE TITLE OF THE LESSON Right angle. ISSUE/PROBLEM (society issue, issue that is seen relevant from pupils’ perspective, issue linked to some nature phenomenon or phenomenon from pupils’ everyday life) Paths between flowerbeds, how to design parallel and rectangular paths between flowerbeds. INVESTIGATIONAL STAGE DESCRIPTION OF THE ACTIVITY Making parallel paths between the beams using a right angle to one of the sides of the beam. TASKS Using a string and a stick, draw a right angle (like drawing with a compass and a ruler), measuring distances on one side of the beam, drawing parallels. The distances between the paths are measured on the side of the beam. Using a string and a stick on the principle of drawing rectangles with a compass (string - compass) draw the measured distances of the rectangle. GOAL OF TASKS Drawn parallels, rectangles and made paths. TEACHING METHODS: (creative-problem solving, resource-based learning, inquirybased learning, setting small groups, teamwork, experiential learning) Creative problem solving, pair work, independent work, research, experiential learning.
