JSS2 Mathematics Scheme of Work(for Nigerian Secondary Schools)

The Junior Secondary School JSS2 Mathematics Scheme of Work is an organized framework guiding second-year junior secondary students through essential mathematics topics.

This curriculum focuses on foundational concepts in numbers, algebra, geometry, and statistics, which help develop students’ problem-solving skills and logical thinking.

The JSS2 Mathematics Scheme of Work is designed to provide students with structured lessons aligned with Nigerian educational standards.

Divided into three academic terms, this curriculum promotes a solid understanding of mathematical principles, ensuring students are well-prepared for advanced studies.

First Term Scheme of Work

1 Numbers and Numeration

• Types of numbers (natural, whole, integers, fractions, and decimals)
• Prime numbers, factors, and multiples
• Converting between fractions, decimals, and percentages
• Introduction to indices and surds

2 Basic Algebraic Expressions

• Understanding variables and constants
• Simplifying basic algebraic expressions
• Rules of indices
• Introduction to linear equations

Example: Simplification of Algebraic Expressions
Simplify the expression:
[
3a + 5a – 2b + 4b
]

Solution

1. Group like terms: ((3a + 5a) + (-2b + 4b))
2. Simplify: (8a + 2b)

Answer: (8a + 2b)

3 Geometry and Shapes

• Types and properties of angles
• Basic properties of shapes (triangles, rectangles, and circles)
• Introduction to polygons
• Calculating perimeter and area for simple shapes

Example: Finding the Area of a Circle
Find the area of a circle with a radius of 7 cm ((\pi = 3.14)).

Solution

1. Use the formula: (\text{Area} = \pi r^2)
2. Substitute (r = 7): (\text{Area} = 3.14 \times 49 = 153.86 \, \text{cm}^2)

Answer: (153.86 \, \text{cm}^2)

4 Simple Statistics

• Collection and organization of data
• Calculating mean, median, and mode
• Interpreting data through bar charts and pictograms

Example: Calculating the Mean
Find the mean of 5, 8, 12, 15, and 20.

Solution

1. Sum the values: (5 + 8 + 12 + 15 + 20 = 60)
2. Divide by 5: (\text{Mean} = \frac{60}{5} = 12)

Answer: The mean is 12.

3. Second Term Scheme of Work

1 Graphs and Charts

• Coordinate points and plotting on graphs
• Line graphs and bar charts
• Drawing and interpreting pie charts
• Applications of graphs in data representation

2 Ratios, Proportions, and Rates

• Definition and calculation of ratios
• Simplifying ratios and solving ratio problems
• Understanding proportions and rates
• Real-life applications in ratio and rates

3 Algebraic Equations

• Formulating and solving linear equations
• Applying equations to solve word problems
• Introduction to simultaneous equations

Example: Solving a Simple Algebraic Equation
Solve for (x):
[
5x – 3 = 2x + 9
]

Solution

1. Move (x) terms to one side: (5x – 2x = 9 + 3)
2. Simplify: (3x = 12)
3. Divide by 3: (x = 4)

Answer: (x = 4)

4 Basic Geometry and Angles

• Further study on angles (alternate, corresponding, and vertically opposite angles)
• Angle sums in polygons
• Applying angle properties in geometry

4. Third Term Scheme of Work

1 Probability Basics

• Understanding probability as a concept
• Simple events and outcomes
• Calculating basic probability

Example: Calculating Probability
A bag contains 3 red balls, 2 blue balls, and 5 green balls. Find the probability of picking a red ball.

Solution

1. Total balls: (3 + 2 + 5 = 10)
2. Probability of red: (\frac{3}{10})

Answer: (\frac{3}{10})

2 Advanced Statistics

• Frequency tables and cumulative frequency
• Mean, median, mode, and range with grouped data
• Introduction to histograms

3 Further Geometry

• Properties of circles (radius, diameter, circumference)
• Area and circumference of circles
• Properties of regular polygons

4 Real-life Applications in Math

• Budgeting and financial literacy
• Applying ratios, percentages, and proportions in daily life
• Time and distance calculations
