**SHAPES & SPATIAL UNDERSTANDING**

• Draws a circle free hand and with compass.

• Identifies centre, radius and diameter of a circle.

• Uses Tangrams to create different shapes.

• Tiles geometrical shapes: using one or two shapes.

• Chooses a tile among a given number of tiles that can tile a given region both intuitively and experimentally.

• Explores intuitively the area and perimeter of simple shapes.

• Makes 4-faced, 5-faced and 6-faced cubes from given nets especially designed for the same.

• Explores intuitively the reflections through inkblots, paper cutting and paper folding.

• Reads and draws 3-D objects, making use of the familiarity with the conventions used in this.

• Draws intuitively the plan, elevation and side view of simple objects.

**Numbers**

**NUMBERS AND OPERATIONS**

• Writes multiplication facts.

• Writes tables upto 10 × 10.

• Multiplies two and three digit numbers using 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.

• Applies the four operations to life situations.

• 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. 7 × 6 = 5 × 6 + 2 × 6).

**FRACTIONAL NUMBERS**

• Identifies half, one fourth and three- fourths of a whole.

• Identifies the symbols.

• Appreciates equivalence.

**Money**

**MONEY**

• Converts Rupees to Paise.

• Adds and subtracts amounts using column addition and subtraction with regrouping.

• Uses operations to find totals, change, multiple costs and unit cost.

• Estimates roughly the totals and total cost.

**Measurement**

**LENGTH**

• Relates metre with centimetre;

• Converts metre into centimetres and vice versa.

• Solves problems involving length and distances.

• Estimates length of an object and distance between two given locations. WEIGHT

• Weighs objects using a 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.

• Justifies the reason for the need of a leap year.

• Reads clock time to the nearest hours and minutes.

• Expresses time, using the terms, ‘a.m.’ and ‘p.m.’

• Estimates the duration of familiar events.

• Finds approximate time elapsed by (to the nearest hour) forward counting.

• Computes the number of days between two dates.

**Data Handling**

• Collects data and represents in the form of bar graphs;

• Draws Inferences by discussing with the teacher.

**Patterns**

• Identifies patterns in multiplication and division: multiples of 9,

• Casts out nines from a given number to check if it is a multiple of nine.

• Multiplies and divides by 10s, 100s. Identifies geometrical patterns based on symmetry.
