Properties of Shape - Right Angles in Shapes - Presentation

In a series of engaging teaching slides, students are introduced to the concept of right angles within the context of shapes. The lesson begins with a discussion, prompting students to identify and understand what a right angle is and encouraging them to look for examples within their classroom environment. The presentation highlights that a right angle can be recognized by a square symbol in the corner of shapes and emphasizes that regardless of orientation, a right angle remains the same. To deepen understanding, students are challenged to create their own right angle tester and use it to identify right angles in various shapes.

Subsequent activities encourage students to explore right angles further through practical exercises. They are asked to fill in the blanks to express fractions of a turn in terms of right angles and to practice making turns with a clock, visualizing a right angle as a quarter turn. Additionally, students are invited to draw lines on dotted patterns to form right angles and to evaluate shapes to determine the presence of right angles, applying their knowledge to ascertain the truth of given statements. Independent work tasks include sorting shapes based on their right angles and identifying odd ones out. Discussion points prompt students to consider the number of right angles in different turns, to identify right angles in their surroundings, and to categorize shapes based on the presence or absence of right angles, fostering a comprehensive understanding of this fundamental geometric property.
