Class 6 Maths - ODISHA
Playing with Constructions
The chapter 'Playing with Constructions' in Class 6 Mathematics introduces students to the foundational tools of geometry, such as the ruler, compass, divider, set-squares, and protractor. Students learn how to draw basic geometric shapes with precision rather than freehand sketching. Key topics include drawing line segments of given lengths, constructing perpendicular lines, bisecting angles, and drawing circles of specific radii. Mastering these practical drawing skills is crucial for students as they form the stepping stones for advanced geometrical problem-solving in board exams and higher classes.

Line Segment
A part of a line with two endpoints that can be measured and constructed using a ruler and compass.
Perpendicular Bisector
A line that divides a given line segment into two equal halves at a right angle (90 degrees).
Angle Bisector
A ray that divides a given angle into two exact equal halves using a compass and ruler.
Circle
A closed curved figure where all points on the boundary are at an equal distance from the fixed center point.

Board Exam Info
In the Odisha (BSE) Class 6 Mathematics examinations, this chapter typically carries around 6 to 8 marks. Common question types include step-by-step construction of line segments, drawing specific angles like 60° or 90° using a compass, and bisecting given angles or line segments.
Frequently Asked Questions
Can I use a freehand drawing for construction questions?
No, all constructions must be done precisely using geometric instruments like a ruler, compass, and pencil, and you must leave your construction arcs visible.
Why should I use a compass instead of a protractor for some angles?
A compass allows you to construct certain standard angles like 60°, 30°, and 90° with high mathematical precision without relying solely on a protractor.
Is it necessary to write the steps of construction?
Yes, writing brief step-by-step instructions for how you drew the shape is often required to get full marks in construction questions.
