- 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.”
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...”
- 18:13 “That's 10 times 10. 10 in two forms. That's 10 times 10. 10 in two form. 10 times 10. 10 times 10. Now, going forward, we have that gives categorically equal to 3.14.1.6 divided by 10 times 10 is 100. 100. So, we have 3....”
- 19:01 “Now, with these two examples, we will give you an idea to what pi equation or pi really means. Now, you have some questions, which I expect you to do. You have said calculate 16 divided by 9 in 3 decimal places. 16 divid...”
Factorization of Algebraic Expressions
This lesson covers the factorization of simple algebraic expressions and quadratic expressions. It includes methods for identifying factors and solving related word problems.
- 26:04 “It would be twice the number of girls, so that would be 120 times two. So, 120 times two, that would give us 240. So, when you had 240 plus 120, it would give you 360, total number of students in the school. What problem...”
- 22:49 “There are twice as many boys as there are girls. Now, every word problem gives you an insight to what you want to do. But technique, that means in that school, there are boys and there are girls. But there are twice as m...”
- 07:51 “Let's trace it out. What would be the possible common factors between these things? The possible common factors that can pick up, pick out themselves. Looking at it carefully, what do we have? We have 3, top up, a 3. We...”
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...”
- 30:51 “So what do we have? K multiplied by... What is the old one that you have? You have 1.5. It is the old one. The old one is given to be 1.5. 1.5. So remember, we have gotten our K. What is our K? Our K has already been arr...”
