Area of trapezoids

    Welcome back with me,,, hihihi... Today we will learn about measured the are of Trapezoid... Do you know, what is trapezoid??? Could you mentioned the kind of Trapezoid around you now??? If you can, could you measured that area?? Okay, if you don't know, how to measured the area of Trapezoid, let's check this video out...

How about the video?? cool..???? hohoho... is it clear for you??? good luck..!!!

Volume of Cube

  On this occasion we will discuss about the volume of a built three dimentional. Before that, you already know the all kinds of three Dimentional, right?? such as cubes, blocks, prisms, cones, etc. but for now, i want to explain you about volume a cube. you know that, every volume of three dimentional have formula :                

Volume : Base Area x Height

So, have you understood with my explaination??? hohohoho... if want to more understand about Cube's volume, Let's see the video below....

 

well... how??? do you more understand than before??? 

you can challange your skill on the link below..

than, you choose: seventh grade>geometry>volume

 good luck.. :)

    There are  many shape in the world, and they are exist around us... do you want to know????

    Watching these video for you know that many shape exist around us. But, before we watch the video2 first we have to watch the video1 to know all kind of shapes.

Video 1

 After you watching the video1, now you take your pencil and paper, than you watching the video2. after you watching the video2, write down the shape that you found from the video2 to paper.

Mathematic is....

            Mathematics is one subject that is often a scourge of nearly every school. It's not a few students who do not like math, because of the difficulty, complexity, logically, etc. Math word itself comes from the Greek that have meaning to know or want to learn. Mathematics itself has existed since ancient times, there is even a suspicion that this inexact science has existed since prehistoric times, and growing up as we know it today. That said, the first prehistoric people used the mathematical sciences is merely to count the number of prey, catch, or harvest them. But look now, there is math everywhere. Market, the streets, in stores, in bus station, anywhere on this world wide all attached with mathematics. Mathematics also can found in other subject, such as physic, biology, economic, etc. Everything in the world have connection with mathematics.
