Sample Practicals for Mathematics (211)

Below are five sample practicals from the NIOS Class 10 Mathematics (211) syllabus. For the complete set of 30 practicals, contact Unnati Education at +91 8800 777430.

Practicum 1: Verification of the Identity (a+b)² = a² + 2ab + b²

Objective: To verify the algebraic identity (a+b)² = a² + 2ab + b² using geometric representation.

Materials Required: Graph paper, ruler, pencil, colored pens.

Procedure: Take a = 3 cm, b = 2 cm. Draw a square of side (a+b) = 5 cm. Divide it into four parts: two squares (a², b²) and two rectangles (ab each). Calculate areas: (a+b)² = 5² = 25 cm²; a² = 3² = 9 cm², b² = 2² = 4 cm², 2ab = 2×3×2 = 12 cm². Verify total area.

Observations: Total area = 25 cm²; a² + 2ab + b² = 9 + 12 + 4 = 25 cm². Identity verified.

Conclusion: The geometric method confirms the algebraic identity (a+b)² = a² + 2ab + b².

Diagram: Square of side 5 cm divided into a² (9 cm²), b² (4 cm²), and two ab rectangles (6 cm² each).

Practicum 5: Finding HCF of Two Numbers by Division Method

Objective: To find the Highest Common Factor (HCF) of two numbers using the division method.

Materials Required: Notebook, pen, calculator (optional).

Procedure: Choose two numbers, e.g., 48 and 18. Divide 48 by 18, record quotient and remainder. Divide 18 by remainder. Repeat until remainder is 0. The last non-zero divisor is the HCF.

Observations: 48 ÷ 18 = 2 (remainder 12); 18 ÷ 12 = 1 (remainder 6); 12 ÷ 6 = 2 (remainder 0). HCF = 6.

Conclusion: The division method accurately determines the HCF, useful for simplifying fractions.

Diagram: Step-by-step division process with numbers 48 and 18.

Practicum 15: Sum of Angles of a Triangle is 180°

Objective: To verify that the sum of angles in a triangle is 180°.

Materials Required: Protractor, ruler, paper, pencil.

Procedure: Draw a triangle ABC with sides 5 cm, 6 cm, 7 cm. Measure angles ∠A, ∠B, ∠C using a protractor. Sum the angles and verify if they equal 180°.

Observations: ∠A = 60°, ∠B = 70°, ∠C = 50°. Sum = 60 + 70 + 50 = 180°.

Conclusion: The sum of angles in a triangle is always 180°, confirming a fundamental geometric property.

Diagram: Triangle ABC with angles labeled (60°, 70°, 50°).

Practicum 19: Verification of Pythagoras Theorem

Objective: To verify Pythagoras theorem in a right-angled triangle.

Materials Required: Graph paper, ruler, pencil.

Procedure: Draw a right-angled triangle with sides 3 cm, 4 cm (legs), and 5 cm (hypotenuse). Construct squares on each side. Calculate areas: 3² = 9 cm², 4² = 16 cm², 5² = 25 cm². Verify if area of square on hypotenuse equals sum of areas on legs.

Observations: 9 + 16 = 25 cm², matches 5² = 25 cm². Theorem verified.

Conclusion: Pythagoras theorem (a² + b² = c²) holds for right-angled triangles.

Diagram: Right triangle with squares on sides (3 cm, 4 cm, 5 cm).

Practicum 25: Total Surface Area of a Cube

Objective: To find the total surface area of a cube using a physical model.

Materials Required: Cardboard, ruler, scissors, glue.

Procedure: Construct a cube with side 4 cm using cardboard. Calculate total surface area using formula 6a², where a is side length. Measure each face and verify.

Observations: Side = 4 cm, each face area = 4² = 16 cm², total surface area = 6 × 16 = 96 cm².

Conclusion: The formula 6a² accurately calculates the total surface area of a cube.

Diagram: Cube with side 4 cm, showing six faces.
