Properties of shape - Right angles in shapes​ - Presentation

In the engaging and interactive presentation on 'Right Angles in Shapes,' students are encouraged to explore and recognise right angles within various shapes. Initially, they are prompted to discuss what a right angle is and to observe right angles in their classroom environment. A right angle is depicted with a square in the corner, symbolising its 90-degree nature. The lesson emphasises that a right angle maintains its definition regardless of its orientation, challenging students to identify right angles in different positions. This foundational understanding is crucial as students begin to interact with shapes and angles in a more complex manner.

The presentation progresses with a series of activities designed to deepen the students' understanding of right angles. Activity 1 suggests creating a right angle tester to identify right angles in multiple contexts. Subsequent activities involve filling in the blanks to connect fractions of turns with the corresponding number of right angles, providing a practical application of the concept. Students are also encouraged to practice making turns with a clock, visualising a right angle as a quarter turn. The hands-on activities culminate in reasoning exercises where students draw lines to form right angles and evaluate statements about the presence of right angles in given shapes. Independent work tasks further challenge students to identify odd shapes out, count right angles, and create their own illustrations incorporating right angles, all while fostering critical thinking and reinforcing their geometric knowledge.
