Algebraic Language and Equations

WATCH THE VIDEO OF THE COMPLETE ACTIVITY

⚠️ This material is an adapted Mathematics activity designed to introduce Algebraic Language and Equations in a visual, progressive, and accessible way.

Number of questions in the activity:

7 adapted questions + complete answer key, distributed across 2 activity pages.

The activity follows a progression designed to help students understand Algebra before moving on to more abstract procedures. It begins with recognizing patterns, introduces the letter x as a representation of an unknown number, works on translating verbal language into algebraic language, introduces like terms and substitution of values, and finally reaches a simple first-degree equation.

Target audience:

The material can be used in middle school and high school, according to the student's curriculum adaptation needs. The file includes skills related to the Algebra thematic unit for both educational levels.

It may especially support students with mild to moderate Intellectual Disabilities, Autism Spectrum Disorder (ASD), difficulties in Mathematics and algebraic reasoning, difficulties with reading and interpreting mathematical information, and difficulties with abstraction.

It can also support Mathematics teachers, general education teachers, support professionals, and Specialized Educational Assistance (AEE) teachers.

Content covered:

The activity covers number sequences, algebraic language, variables, unknown numbers, algebraic expressions, double, triple, half, like terms, simplifying expressions, substituting the value of a variable, and simple equations.

Important information for teachers:

In the first question, students observe a visual sequence consisting of 3, 6, 9, and 12 elements and identify the next number. In this way, the activity begins with recognizing a pattern before moving directly into symbolic language.

In the second question, a box represents the unknown number x, while five small blocks represent the quantity being added. Students identify which expression represents the situation “a number x increased by 5.” This visual resource helps make the idea of x + 5 more concrete.

The third question works on translating verbal language into algebraic language, matching expressions such as “twice a number,” “a number increased by 7,” “three times a number,” and “half of a number” with their corresponding mathematical representations.

In the following questions, students identify like terms in an expression and learn that terms with the same variable part can be combined. The activity itself explains that 5x and 3x can be combined because they have the same variable part before asking students to determine the result.

Next, the activity presents 2x + 3 and states that x = 4. The calculation is organized into steps with spaces to complete, helping students understand how to substitute a variable with its numerical value before carrying out the operations.

Finally, the equation x + 4 = 10 is introduced through the question, “What number added to 4 equals 10?” This approach connects the concept of an equation to intuitive reasoning that may be easier for students to understand initially.

Key features:

✅ Introduces Algebra in a visual and progressive way.

✅ Builds a bridge between concrete situations → verbal language → algebraic representation.

✅ Uses different response formats: selecting, observing, matching, and calculating.

✅ Presents calculations in small, manageable steps, reducing the level of abstraction required.

✅ Connects terms such as double, triple, half, and increased by with their corresponding algebraic expressions.

✅ Available in UPPERCASE TEXT, with visual support, BNCC-related skills, and a complete answer key.
