Teachers check how well students can evaluate algebraic expressions using different methods. Here are the main ways they do this:

1. Formative Assessments:

   • Quizzes and tests during class count for 30% of continuous assessment.
   • Regular homework is worth 20% of the overall grade.

2. Diagnostic Assessments:

   • Pre-tests at the beginning of a unit help teachers see what students already know and where they might need help.

3. Summative Assessments:

   • Final exams at the end of the term usually count for 50% of the final grade. These exams include questions that ask students to evaluate expressions, like $2x + 3$ when $x = 4$.

4. Practical Applications:

   • Students get to solve real-life problems using algebraic expressions. This method makes learning more interesting and helps them understand better.

By using these different methods, teachers can get a complete picture of how well students are doing in this important part of math.
