Mathematics Lesson Note For JSS2  (SecondTerm)

Below are the 2022 complete JSS2 Second Term Mathematics Lesson Note 

Week Two: Simple Equations

INTRODUCTION:

An algebraic expression in mathematics is an expression that is made up of variables and constants, along with algebraic operations (addition, subtraction, etc.). Expressions are made up of terms. It does not have an equals (=) sign.

An algebraic equation is a mathematical statement that contains a combination of numbers, symbols, variables and mathematical operators. It has an equals (=) sign. To learn more, click here.

Week Three: Linear Inequalities

INTRODUCTION:

In mathematics we use the equals sign, =, to show those quantities are the same. However, very often, quantities are different, or unequal. For example, a mother is always older than her child their ages are always different. We say that there is inequality in their ages. This chapter explains the use of inequalities in arithmetic, algebra and in everyday life. It also introduces the inequality symbols.  To learn more, click here.

Week Four: Linear Inequalities- Graphical Representation

INTRODUCTION:

Linear Inequality (Graphical Representation)

Inequalities with one variable can be plotted on a number line, as in the case of the inequality x ≥ -2:

Week Five: Graphs of Linear Equations

INTRODUCTION:

Linear Graphs

graph is a picture that represents numerical data. Most of the graphs that you have been taught are straight-line or linear graphs. This topic shows how to use linear graphs to represent various real-life situations.

If the rule for a relation between two variables is given, then the graph of the relation can be drawn by constructing a table of values.

To plot a straight line graph we need to find the coordinates of at least two points that fit the rule.  To learn more, click here.

Week Six: Plane Figures or Shapes

INTRODUCTION:

Quadrilateral just means “four sides”, (quad means four, lateral means side).

Any four-sided shape is a Quadrilateral.

But the sides have to be straight, and it has to be 2-dimensional. To learn more, click here.

Week Seven: Review of first half term’s work and periodic test

This week, we would be doing a revision of all that we learned, in the first half of the term.

Week Eight and Nine: Scale Drawing

INTRODUCTION:

A drawing that shows a real object with accurate sizes except they have all been reduced or enlarged by a certain amount (called the scale). The scale is shown as the length in the drawing, then a colon (“:”), then the matching length on the real thing.

For example, this drawing has a scale of “1:10”, so anything drawn with the size of “1” would have a size of “10” in the real world, so a measurement of 150mm on the drawing would be 1500mm on the real horse.

Since it is not always possible to draw on paper the actual size of real-life objects such as the real size of a car, an aeroplane, we need scale drawings to represent the size like the one you see below of a van.  To learn more, click here.

Week Ten: Revision

This week, we would be doing a revision of all that we learned during the term.

Week Eleven: Examination

Afterwards, we would write an examination, which would test our knowledge of what has been taught so far.
