⚠️ 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 operations with integers in real-life problem situations (temperature, stairs, bank balance, and elevator).
Target Audience:
Students in Elementary School (Early and Middle Years), 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 (stairs, thermometer, elevator, and financial situations), accessible language, and objective activities, with 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 integers in a concrete and visual way (going up/down, gaining/losing).
✅ Uses stairs to represent addition and numerical movement.
✅ Applies concepts to real-life situations: temperature, money, and elevators.
✅ Introduces an important rule: subtracting a negative becomes addition.
✅ Encourages interpretation before calculation (problem-solving).
✅ Objective questions with answer choices that support decision-making.
✅ Progressive teaching sequence: understand → interpret → calculate → apply.
✅ Reduces mathematical abstraction through consistent visual support.
✅ Can be used in regular classrooms, AEE, or individual support.
✅ Ready-to-use adapted assessment.
✅ Saves 3h42min of teacher planning time.
