Number of questions: 5 adapted activities, including marking, comparison, visual interpretation, coefficient identification, and analysis of simple graphs.
Target audience:
Students with difficulties in reading, abstraction, and mathematical interpretation. Recommended for Grades 8–9 and High School. Also suitable for students with Intellectual Disabilities (mild to moderate), Autism, ADHD, Dyslexia, Down Syndrome, Apraxia, and students in the process of mathematical literacy.
Format:
Color-print PDF with strong visual support: graphs with colored arrows, characters, support icons, color-coded coefficients a and b, and concrete images such as a small car moving in a straight line. Includes full answer key.
Objective:
To help students understand what a linear function is by identifying:
the general expression f(x) = ax + b
exponent 1
increasing or decreasing behavior
graph in the shape of a straight line
The material transforms abstract concepts into concrete and visual elements, making learning accessible.
Themes:
Linear function; coefficients a and b; graph; straight line; increasing and decreasing behavior.
Methodology:
Progressive activities including multiple-choice marking, visual analysis, pattern recognition, comparison between circle × parabola × straight line, and identification of numerical values.
Exercises:
Identify which expression has exponent 1 (p. 5).
Identify the correct graph of a linear function (p. 6).
Compare the motion of the small car and associate it with a straight-line graph (p. 7).
Find the values of a and b in four different expressions (p. 7).
✅ Strong visual support (simple graphs, colored arrows, characters, and symbols).
✅ Direct language—ideal for neurodivergent students and mathematical beginners.
✅ Comparisons that reduce abstraction: circle × parabola × straight line.
✅ Clear visual explanation of increasing and decreasing functions.
✅ Saves 6h10min of teacher preparation time (information shown on the cover).
