Unit 13
This math unit starts with basic geometry, focusing on identifying and classifying angles—acute, obtuse, right, and straight—through various visual and descriptive methods. As the unit progresses, it shifts from angle recognition alone to detailed triangle classification based on angle types. Students learn to categorize triangles as acute, obtuse, or right by visual inspection and definition matching, gradually deepening their understanding of these concepts. The unit then expands to encompass comprehensive triangle classification by including side lengths along with angle types. Students engage with identifying and distinguishing between scalene, isosceles, and equilateral triangles, first through direct illustration-based identification, then progressing to more complex tasks involving matching descriptions to triangle images and vice versa. This detailed approach, extending from simple angle identification to complex triangle classification, equips students with a thorough understanding of geometric properties and relationships within triangles.
