Mathematical Functions through Sets

WATCH THE FULL ACTIVITY VIDEO

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

Number of questions in the activity:
5 adapted questions + complete answer key, involving mathematical functions, relations between sets, number patterns, interpretation of mathematical rules, association between input and output, and everyday problem situations.

Target Audience:
Students in 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 difficulties in Mathematics.

Format:
Color printable PDF with strong visual support (sets, arrows, balls, apples, bread, and groupings), simple uppercase language, interactive activities (completing, matching, multiple choice, and interpretation), and answer key included.

Important for the teacher:
This material was developed as a practical activity with questions and can be used as:
✔ content introduction
✔ learning reinforcement
✔ adapted assessment

Key Features:

✅ Teaches mathematical functions in a concrete and visual way.
✅ Explains the idea of input → rule → result using drawings and groupings.
✅ Introduces simple functions such as f(x)=2x and f(x)=3x+1 in an accessible way.
✅ Uses everyday examples (balls, apples, bread, and popsicles).
✅ Develops recognition of mathematical patterns and regularities.
✅ Includes matching activities between sets, facilitating understanding of mathematical correspondence.
✅ Contextualized problem situation (bakery), connecting Mathematics to real life.
✅ Explores multiple choice and interpretation of functions gradually.
✅ Progressive teaching sequence: observe → relate → calculate → interpret.
✅ Simple language with strong visual support, reducing algebraic abstraction.
✅ Develops logical reasoning and introductory algebra understanding.
✅ Can be used in regular classrooms, AEE, or individual support.
✅ Ready-to-use adapted assessment.
✅ Saves 6h17min of teacher planning time.
