About This Lesson
Ever wondered how to teach classifying triangles by sides and angles in an engaging way to your 5th-grade students? In this lesson plan, students will learn about how to classify triangles by sides (equilateral, isosceles, scalene) as well as classify triangles by angles (acute, obtuse, right). Through artistic, interactive guided notes, check for understanding, practice coloring worksheet, and a maze, students will gain a comprehensive understanding of triangle classification. Students will be given examples of each type of triangles as well as triangles that may fall into multiple category (i.e. an isosceles acute triangle).
The lesson ends with a real-life example that explores how understanding the properties of triangles can be applied in everyday scenarios. Students will read and write about the real-life uses of classifying triangles, connecting their learning to practical situations.
