Place of Mathematics education in the curricular framework is positioned on twin concerns.

• What Mathematics education can do to improve the score of students in summative examination and how it can help to choose right stream in higher classes?

• What Mathematics can do to retain every child in school and how it can help them to be self-dependent?

• What Mathematics education can do to improve communication skills of every child and how it can make them employable after school?

• What Mathematics education can do to engage the mind of every student and how it can strengthen the student's resources?

In a Mathematics classroom, emphasis is placed on

• problem solving strategies

• mathematical algorithms and processes

• mathematical content

• mathematical content, process and reasoning

$\mathrm{Factors} \mathrm{of} {\mathrm{x}}^2 +\hspace{0.17em}3\sqrt{2}\mathrm{x} + 4 \mathrm{are}$

• $\left(\mathrm{x} + 2\sqrt{2}\right)\left(\mathrm{x} - \sqrt{2}\right)$

• $\left(\mathrm{x} + 2\sqrt{2}\right)\left(\mathrm{x} + \sqrt{2}\right)$

• $\left(\mathrm{x} - 2\sqrt{2}\right)\left(\mathrm{x} - \sqrt{2}\right)$

• $\left(\mathrm{x} - 2\sqrt{2}\right)\left(\mathrm{x} + \sqrt{2}\right)$

As per national curriculum framework 2005, the sequence of Mathematics

• Before language

• After language

• After science

• After social science

Some students of your class are repeatedly not able to do well in mathematics examinations and tests. As a teacher you would

• give more tests for practice

• explain the consequences of not doing well

• diagnose the causes and take steps for
  remediation

• make them sit with high achievers
