⚠️ This material is an adapted activity with questions (it is not a complete theoretical workbook on the topic).

Number of questions in the activity:
6 adapted questions + complete answer key, covering polygons, angles, the sum of the interior angles of triangles, complementary, supplementary, and explementary angles, as well as contextualized linear equations.

Target Audience:
Middle School, High School, Youth and Adult Education (EJA), and Specialized Educational Support (AEE).

Especially recommended for students with Intellectual Disabilities (mild to moderate), ASD, ADHD, Down Syndrome, and learning difficulties in Mathematics.

Format:
Color printable PDF with strong visual support (illustrated polygons, colorful triangles, angle pairs, contextualized problem situations, and visual examples), simple uppercase language, multiple-choice activities, matching, classification, angle calculations, and solving linear equations, plus a complete answer key.

Important for the Teacher:
This material was developed as a practical activity with questions and can be used as:

✔ Content introduction
✔ Learning reinforcement
✔ Adapted remediation activity
✔ Adapted assessment

Key Features:

✅ Combines Geometry and Algebra in a single adapted activity, promoting integrated learning.

✅ Develops recognition of the main polygons based on their number of sides and vertices.

✅ Builds understanding of the sum of the interior angles of triangles through illustrated examples and calculations of unknown angle measures.

✅ Explores complementary, supplementary, and explementary angles using colorful visual representations.

✅ Helps students understand the relationships between different angle measures before introducing formal mathematical definitions.

✅ Develops geometric reasoning through the identification and comparison of shapes and angle measures.

✅ Introduces linear equations through everyday situations, making Algebra more meaningful and accessible.

✅ Includes problem-solving activities involving shopping and sticker collections, connecting Mathematics to students' daily lives.

✅ Develops logical reasoning, problem interpretation, and the ability to solve simple linear equations.

✅ Uses a variety of teaching strategies, including multiple-choice questions, matching, classification, angle calculations, and contextualized problem-solving.

✅ Progressive learning sequence: observe → identify → relate → calculate → solve.

✅ Simple language, clear instructions, and strong visual support promote student independence.

✅ Significantly reduces the abstraction of Geometry and Algebra concepts.

✅ Suitable for regular classrooms, Specialized Educational Support (AEE), or individual instruction.

✅ Ready-to-use adapted assessment.

✅ Saves 4 hours and 22 minutes of teacher planning time.
