Types of Triangles

Number of activities: 6 adapted exercises including observation, marking, coloring, comparison, and multiple-choice questions.

Target audience:
Students with difficulties in reading, abstraction, and interpretation in Mathematics. Designed for Middle School (7th–9th grades) and High School. Also recommended for students with Intellectual Disabilities (mild to moderate), Autism (ASD), ADHD, Dyslexia, Down Syndrome, Apraxia, and those in the process of geometric literacy development.

Format:
Color printable PDF, featuring clear illustrations, short instructions, real-life examples, and an answer key included.

Objective:
To support learning about the types of triangles (equilateral, isosceles, scalene, right, and obtuse), turning geometric concepts into concrete and visual experiences that enhance spatial reasoning and memory retention.

Content:

Topics: Classification of triangles by sides and angles; recognition and comparison of shapes; understanding of right and obtuse angles.

Methodology: Short activities with observation, coloring, marking, and comparison between triangles, helping students recognize patterns and differences in an intuitive way.

Exercises: Identification of triangle types, marking figures with right angles, observing equal and unequal sides, and choosing correct alternatives.

Highlights:

✅ Simple and visual language that makes geometric learning easier.
✅ Strengthens spatial perception and recognition of patterns through color and shape.
✅ Combines Mathematics and fine motor coordination with practical activities.
✅ Ideal for regular classrooms and special education (AEE) using foam or stick models.
✅ Saves up to 7h15min of teacher preparation time.
