Description

Geometry

SHAPES & SPATIAL UNDERSTANDING • Gets the feel of perspective while drawing a 3-D object in 2-D. • Gets the feel of an angle through observation and paper folding. • Identifies right angles in the environment. • Classifies angles into right, acute and obtuse angles. • Represents right angle, acute angle and obtuse angle by drawing and tracing. • Explores intuitively rotations and reflections of familiar 2-D shapes. • Explores intuitively symmetry in familiar 3-D shapes. • Makes the shapes of cubes, cylinders and cones using nets especially designed for this purpose.

Numbers

 NUMBERS AND OPERATIONS • Finds place value in numbers beyond 1000. • Appreciates the role of place value in addition, subtraction and multiplication algorithms. • Uses informal and standard division algorithms. • Explains the meaning of factors and multiples. MENTAL ARITHMETIC • Estimates sums, differences, products and quotients and verifies using approximation. FRACTIONAL NUMBERS • Finds the fractional part of a collection. • Compares fractions. • Identifies equivalent fractions. • Estimates the degree of closeness of a fraction to known fractions ( 1 2 , 1 4 , 3 4 etc.) • Uses decimal fractions in the context of units of length and money. • Expresses a given fraction in decimal notation and vice versa.

Money  • Applies the four operations in solving problems involving money.

Measurement  LENGTH • Determines area and perimeter of simple geometrical figures. • Applies the four operations in solving problems involving length, weight and volume. • Relates commonly used larger and smaller units of length, weight and volume and converts one to the other. • Applies simple fractions to quantities. • Converts fractional larger unit into complete smaller units. • Appreciates volume of a solid body: intuitively and also by informal measurement. • Uses addition and subtraction in finding time intervals in simple cases

Data Handling

• Collects two-dimensional quantitative data. represents the data in the form of a table. • Draws a bar graph or a pictograph to present a data.

 Patterns • Identifies patterns in square numbers, triangular numbers. • Relates sequences of odd numbers between consecutive square numbers. • Makes border strip and tiling patterns.
