Quadratic Function

Number of activities: 6 adapted exercises involving expression analysis, coefficient identification, graph interpretation, marking, and parabola coloring.

Target audience:
Students with difficulties in reading, abstraction, and mathematical interpretation. Designed for 9th grade (Middle School) 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 numerical literacy.

Format:
Color printable PDF, with accessible language, visual examples, explanatory icons, and an answer key included.

Objective:
To help students understand the concept of quadratic functions, exploring the relationship between coefficient values and the shape of the graph (parabola) in a concrete and visual way.
The material connects Math and Physics by representing the path of a kicked ball as an example of parabolic motion.

Content:
Topics: Quadratic function; coefficients a, b, and c; parabola concavity; function graphs; general form recognition.
Methodology: Progressive activities with observation of equations, coloring, matching, and filling in coefficient values.
Exercises: Identify quadratic functions, mark graphs, color positive and negative parabolas, and determine a, b, and c values in given expressions.

Highlights:
✅ Visual and inclusive resource that reduces mathematical abstraction.
✅ Simple language and color-coded coefficients (a, b, c) to reinforce visual memory.
✅ Practical connection with real-life examples and interdisciplinary links to Physics.
✅ Suitable for general education and special education (AEE) with concrete and digital supports.
✅ Saves up to 5h15min of teacher preparation time.
