## TERM-I

Class 1 Mathematics NCERT textbook has 13 chapters in which TERM I has 6 chapters.

Starting from shapes and space to counting numbers upto 50. Class 1 Maths is beautifully bifurcated into various chapters in which student actively learn by doing various activities under the guidance of a teacher.

Various activities are beautifully drawn and presented in such a manner that student feels connected with the activities. Whether solving exercise or filling or outlining the shapes and numbers, students are very much engaged in completing the various tasks allotted to them.

The detailed syllabus has been discussed below along with the Key Concepts and Learning outcomes. So that learning can be Joyful.

## Chapter 1: Shapes and Space

- Spatial relationship (position of the objects)
- Use spatial concepts like inside/outside above/below, top/bottom and far/nearest.
- Identify and draw things which are near-far, inside-outside, above-below etc.
- Compare the size of the objects. (smaller-bigger, taller -shorter, Small-smaller–smallest) etc.
- Sort and describe the objects on the basis of shapes
- Sort 2-D shapes such as flat objects made of card etc. Sorting according to shapes.
- Objects that roll and slide- sold objects round sided and flat ones.
- One-to-one correspondence

- Identify the spatial relationship of the objects.
