Similar Shapes
This lesson covers the identification of similar shapes such as triangles, rectangles, squares, cubes, and cuboids. It explains the criteria for similarity, including proportional sides and equal angles. The lesson also includes methods for enlarging figures using scale factors and calculating lengt
- 25:22 “these 2, if it cannot be in this form then your answer is wrong, now the last part is applying it to water problem, how do we apply it to water problem, how using your scalar factor to solve a problem, olatical wants to...”
- 23:43 “triangle, BAC, that's remember from the scalar, from the scalar that we meant comparison, now you will see why the scalar of 2 can also be checked, so that gives me 384, the bigger one, over 96, now if you look at 96, so...”
- 11:57 “smaller one, what longest side of the smaller one, that's 9. Because of this point, decimal place, you multiply by 10. So, when you multiply, because of the decimal place, to take it off, you are going to be having 2.5,...”
Translating Word Problems into Equations
The lesson teaches how to translate word sentences into mathematical equations. It covers the use of variables to represent numbers and how to express word problems as algebraic expressions. Students will learn to solve simple equations and check their answers.
- 19:25 “We've come to the end of today's class. Thank you so much for watching. My name is Dorkas Aoye, till next time.”

- 15:18 “So A equals 8 over 3. So A is 8 over 3. The question is to determine the rest. So if A is 8 divided by 3, the rest is A plus 1. The first is A plus 1, which is 8 over 3 plus 1. The second is A plus 2, which is 8 over 3 p...”
Multiplication in Binary Numbers
This lesson covers the multiplication of 2-digit and 3-digit binary numbers. It explains the basic rules of binary multiplication and how to apply them in calculations. Students will learn to perform binary multiplication without borrowing.
- 00:00 “Hello, my name is Oyase Sonday. I'll be taking you madmatis jsS3 class. We're looking at an interesting topic for today that says multiplication of numbers in base 2 numerals, multiplication of numbers in base 2 numerals...”

- 06:09 “which is called the one. So, let the one goes now. One time this. You remember, you have started, you have left 2. So, you're starting, you've left 2 first to start from the third, you get it. So, you've left 2, you're s...”
Simplification of Algebraic Expressions
This lesson covers the definition of algebraic expressions and their components, including terms and coefficients. It explains how to identify like terms, perform arithmetic operations on similar terms, and simplify expressions by inserting or removing brackets.
- 01:36 “Here we deal with alphabets majorly, such as X or Y to represent the unknown values. Here are some examples of algebraic expressions. We have two X plus 10 Y plus one. You can note that it does not have an equal sign. Wh...”
- 02:23 “Another example is minus 3m minus 7n plus 2. This is also an algebraic expression. I'll move on to terms. Algebraic expressions are made up of terms that are separated by an addition or subtraction sign. The algebraic ex...”
- 07:10 “Two multiplied by c. That is what it means. So the following expressions using a simple annotation. Y plus y plus y plus y. Instead of writing all of that, you just have five y. The same thing with 8 times b gives you 8...”
Trigonometric Ratios
This lesson covers the identification of sine, cosine, and tangent of an acute angle. It explains how to apply these trigonometric ratios to solve problems involving distances and lengths in right-angled triangles. The relationship between the sides and angles of triangles is also discussed.
- 00:00 “Hello, my name is Oyase, Sunday I'll be taking you mathematics for JSS3 and we have an interesting topic for today, which is trigonometry, an aspect of our measurement and geometry. And the question is what to be the foc...”
- 14:14 “that is given, then your hypotenuse. So, I could read, you could know, the particular one to apply. They are designed to cause all the time. Thank you very much. We've come to the end of the class. My name is Oyase Sunda...”
- 08:28 “And that is the side which is 1447.14 m. Cest is the representation. Once you can represent it out, it is easier to solve. Now you simply look at this. What are the size that are given? We are given the opposite and we a...”
Rational and Non-Rational Numbers
This lesson covers the identification of rational and non-rational numbers. It explains the characteristics of different number sets, including natural numbers, whole numbers, and integers. The lesson also discusses the significance of the number PI in relation to circles.
- 00:10 “Hello, I'm Oyase Sunday, and I'm taking Matamatics JSS 3 class. We're treating an interesting topic for today. And the topic is rational and non-rational numbers. We're taking it from the numbers and numerations. Now wha...”
