- Identifies the center, radius, and diameter of a circle.
- Creates different shapes using tangrams etc.
- Tiles geometrical shapes: using one or two shapes. Equilateral triangle/ Hexagon.
- Explores intuitively the perimeter and area of simple shapes.
- Makes 4-faced, 5-faced, and 6-faced solids from given nets specially designed for the same.
- Reads and draws 3D objects, making use of the familiarity with the conventions used in this.
- Rotates a coin to generate a sphere.

### 2. Numbers

- Numbers and operations
- Writes multiplication facts.
- Writes tables’ up to 10 x 10.
- Multiplies two and three-digit numbers using the lattice algorithm and the standard (column) algorithm.
- Divides a given number by another number in various ways such as:
- By drawing dots.
- By grouping.
- By using:
- multiplication facts.

- By repeated subtraction.

- Frames word problems.
- Estimates sums, differences, and products of given numbers.

- Mental Arithmetic
- Adds and subtracts multiples of 10 and 100, mentally.
- Completes multiplication facts by adding partial products, mentally (e.g. 7x6 = 5x6+2x6).
- Appreciates equivalence of 2/4 and 1/2; and of 2/2, 3/3, 4/4, and 1.

- Draws Inferences through discussions.

### 6. Patterns

- Identifies patterns in multiplication and division eg: multiples of 9,
- Casts out nines from a given number to check if it is a multiple of nine.
- Identifies patterns.
- Multiplies and divides by 10s, 100s.
- Identifies geometrical patterns based on symmetry.
