To prepare students for successful careers (especially ones that involve Mathematics), there is need to refocus the manner/style with which the subject is taught in schools. I understand that teachers are hardly even in charge of designing the curriculum. But then again, they are the ones who actually teach it and could always tweak it

Algebra is one of the important aspects of Mathematics. It helps us make connections between different things, to express them using equations, and to see how they will work out. And because Algebra is an integral part of Maths, you need to know how to solve such problems successfully. Consider the diagram shown below, which

JSS 3 Mathematics First Term Week 6 Topic: FORMULAE: SUBSTITUTION AND CHANGE OF SUBJECT Formulae and substitution A formula is an equation with letters which stands for quantities. For example C = 2πr Is the formula which gives the circumference, c, of a circle of radius r. In science, I = V/R Is the formula
JSS 3 Mathematics First Term Week 5 Topic: CALCULATION USING STANDARD FORM Standard index form Standard index form is also known as standard form. It is very useful when writing very big or very small numbers. In standard form, a number is always written as: a × 10 n a is always between 1 and 10. n tells

Word problems are seen in our everyday lives. This involves sum, difference, positive difference and product of numbers. The most important thing you need to remember in solving word problems is the INTERPRETATION OF THE QUESTION. If you’re able to correctly interpret the question, the solution becomes easy. Sum – the result of addition Difference

MATHEMATICS SS 1 SECOND TERM WEEK 3 Topic: GENERAL FORM OF QUADRATIC EQUATION LEADING TO FORMULA METHOD. Quadratic equation refers to polynomial equation that have a general form of ax2+bx+c=0, where a, b and c are co-efficient. a≠0 otherwise it would be a linear equation and c is constant. The quadratic formula is defined as x=

SSS 1 Mathematics Week 3 Topic: Addition, Subtraction, Multiplication and Division of Number Bases Let’s first take a look at decimal addition. As an example we have 26 plus 36, 26 +36 To add these two numbers, we first consider the “ones” column and calculate 6 plus 6, which results in 12. Since 12 is greater
Logarithm of Number Less Than 1 The characteristics of the logs of all numbers equal to or greater than 1are equal to or greater than 0, i.e. are all positive or zero, if m is the characteristics of all log10 N where N is greater than or equal to 1 then m is greater than
