Class 1 Maths - ODISHA
What is Long? What is Round?
The chapter What is Long? What is Round? introduces Class 1 students of the Odisha BSE board to basic geometrical shapes and physical properties of everyday objects. Through fun activities and observations, young learners discover the difference between objects that slide and objects that roll. They learn to identify flat surfaces, curved surfaces, and edges of different shapes. This foundational chapter builds early spatial awareness and observational skills, which are crucial for later geometry concepts in primary mathematics and frequently tested through matching and identification questions in board assessments.

Rolling Objects
Objects with curved surfaces, like balls and marbles, can roll easily on the ground.
Sliding Objects
Objects with flat surfaces, like books and boxes, can slide when pushed but do not roll.
Long Objects
Objects that have greater length compared to their width, such as pencils and sticks.
Round Objects
Objects that are circular or spherical in shape with no sharp corners, such as coins and wheels.
Flat and Curved Surfaces
Flat surfaces help objects stay stable, while curved surfaces allow movement in multiple directions.

Board Exam Info
In the Odisha (BSE) Class 1 Mathematics examinations, this chapter typically carries around 5 to 8 marks. Common question types include matching objects to their properties (rolling or sliding), identifying long and round items from pictures, and classifying given items into flat-surface or curved-surface groups.
Frequently Asked Questions
Why does a ball roll while a book slides?
A ball has a curved surface which lets it roll, whereas a book has flat surfaces that help it slide.
Can an object both slide and roll?
Yes, some objects like a cylinder (like a water bottle) can both roll on their curved side and slide on their flat ends.
How do we know if an object is long?
An object is called long if its length is much greater than its other sides, like a pencil or a ruler.
