Learning Mathematics at upper primary level is about

• gaining understanding of mathematical concepts and their applications in solving problems logically

• learning problem solving techniques only

• learning lots of new formulae and algorithms

• remembering solutions or methods of various types of mathematical problems

Four stages of language development in Mathematics classroom in order are

• everyday language ➔ mathematised situation language ➔ language of Mathematics problem solving ➔ symbolic language

• everyday language ➔ symbolic language ➔ language of Mathematics problem solving ➔ mathematised situation language

   

• everyday language ➔ language of Mathematics problem solving ➔ mathematised situation language ➔ symbolic language

• everyday language ➔ language of Mathematics problem solving ➔ symbolic language ➔ mathematised situation language

In Geometry class of VI grade students, the teacher explained the construction of angles measuring 30°, 60° and 90°, with the help of demonstration of construction and bisector of an angle. Then, she asked the students to construct an angle of 15° and an angle of 45°. This task at this point reflects the teacher's intention to

• assess the learner's performance in summative assessment

• give the exposure of experiential learning

• assess the student's understanding and ability to combine two skills learnt, to accomplish the given task

• engage every student in some work

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?
