• 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.

• Describes rate charts and bills.

### 4. Measurement

• Length
• Relates meter with centimeter;
• Converts meter into centimeters and vice versa.
• Solves problems involving length and distances.
• Estimates the length of an object and distance between two given locations.
• Weight
• Weighs objects using balance and standard units.
• Determines sums and differences of weights.
• Estimates the weight of an object and verifies using a balance.
• Volume
• Measures volumes of given liquid using containers marked with standard units.
• Determines sums and differences of volumes.
• Estimates the volume of a liquid contained in a vessel and verifies by measuring.
• Time
• Computes the number of weeks in a year.
• Correlates the number of days in a year with the number of days in each month.

• Reads clock time to the nearest hours and minutes.
• Expresses time, using the terms, 'a.m.' and 'p.m.'
• Estimates and verifies the duration of familiar events.
• Finds approximate time elapsed by (to the nearest hour) forward counting.
• Computes the number of days between two dates.

### 5. Data Handling

• Collects data and represents in the form of bar graphs;
• 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.  Study Materials for Class 4
