JSS2 Mathematics: Algebraic Fractions & Equations

• JSS2 Mathematics Second Term Curriculum in Nigeria covers: algebraic fractions, simple equations, linear inequalities involving one variable, plane shapes and figures, angles in a polygon, scale drawings, graphs, and angles of elevation and depression.

Algebraic Fractions

• Focuses on simplifying, adding, subtracting, multiplying, and dividing fractions involving variables.
• Understanding how to find a common denominator is crucial for addition and subtraction.
• Simplifying fractions often involves factoring and canceling common factors.

Simple Equations

• Deals with solving equations that contain one variable.
• Uses addition, subtraction, multiplication, and division to isolate the variable.
• Emphasizes the importance of performing the same operation on both sides of the equation to maintain balance.

Linear Inequalities Involving One Variable

• Similar to simple equations but involves inequality symbols (>, <, ≥, ≤).
• Solution is a range of values rather than a single value.
• Multiplying or dividing by a negative number reverses the inequality sign.

Plane Shapes and Figures

• Includes identifying and understanding the properties of shapes such as triangles, squares, rectangles, circles, and parallelograms.
• Calculating area and perimeter/circumference is a key aspect.
• Focuses on understanding the relationships between sides, angles, and diagonals.

Angles in a Polygon

• Covers the properties of angles within polygons, including triangles, quadrilaterals, pentagons, etc.
• The sum of interior angles in a polygon can be calculated using a formula.
• Regular polygons have equal sides and equal angles

Scale Drawings

• Involves creating accurate representations of objects or areas at a reduced or enlarged size.
• Requires understanding of scale and proportion.
• Used in map making, architectural plans, and engineering designs.

Graphs

• Focuses on understanding and interpreting different types of graphs.
• Includes bar graphs, line graphs, pie charts, and pictograms.
• Ability to extract information and make comparisons from graphical data.

Angles of Elevation and Depression

• Deals with angles formed between a horizontal line and the line of sight to an object above (elevation) or below (depression).
• Involves applying trigonometric ratios (sine, cosine, tangent) to solve problems related to heights and distances.
• Understanding right-angled triangles is essential for solving these problems.

Second term curriculum focusing on algebraic fractions, simple equations, and linear inequalities. Simplifying, solving, and graphing equations is crucial. Understanding fractions and inequalities is essential.
