Shadowing Practice: Fractions - Learn English Speaking with Video

In this video we're going to talk about fractions

and I want you to understand the concept of a fraction using visual illustrations.

So let's say if we have a circle.

Let me draw a better looking circle.

And let's split the circle into two equal parts.

Now I'm going to shade only one portion of those two parts.

So what fraction of the circle is shaded?

So there's two parts of the circle and only one of those two parts is shaded.

So we could say that one half of the circle is shaded.

Now let me give you another example.

Let's say if I have a circle and I split it into four equal parts.

And I'm going to shade this part of the circle.

So what fraction of the circle is shaded?

So there's four equal parts of the circle, and three of those four parts were shaded.

So three-fourths of the circle is shaded.

Now let me give you another illustration.

So let's say we have a circle again.

And this time, I'm going to divide the circle into eight equal parts.

So what fraction of the circle is shaded?

So we know that there's eight parts, the circle was divided into eight equal parts, and only three of those eight parts were shaded.

So three-eighths of the circle is shaded.

And so hopefully these visual illustrations help you to understand a concept of a fraction, which is basically a portion out of a whole.

Now here's another example for you.

So let's say we have a rectangle.

And it's broken up into seven congruent parts.

Now granted, my drawing is not perfect, but we'll make it work.

And let's say three of those parts is shaded.

What fraction of the rectangle is shaded and what fraction is not shaded?

So there's seven equal parts, and three of those seven parts are shaded

so we could say three-sevenths of the rectangle is shaded now

out of this total seven parts four of those seven parts is not shaded

so four-sevenths of the rectangle remains unshaded or not shaded Now,

let's look at another example.

So let's say we have a square.

And we're going to break up the square into a total of eight parts.

What fraction of the square is not shaded?

And what fraction is shaded?

So out of the eight parts, five of those parts is shaded.

So we can say that five eighths of the rectangle, or rather, of the square is shaded.

Now what fraction is not shaded?

out of the total eight parts, three parts is not shaded.

So hopefully these visual illustrations help you to solidify the concept of a fraction.

So here's a practice problem for you.

Draw a circle and shade only two-fifths of the circle.

So feel free to pause the video.

So here's a circle, and we'll need to break it up into five equal parts.

So that's going to be one, we'll say two, three, four, and five.

So once you split it into five parts, all you need to do is shade two of those five parts.

And so in this case, two-fifths of the circle has been shaded.

And so that's basically it for this video.

So now you understand fractions with circles and squares and rectangles.

So that's basically it for this video.

and if you need help with adding or subtracting fractions

or even multiplying

and dividing fractions I'm going to post a few links in the description section of this video

so you can take a look at that when you get a chance.

Thanks for watching.

¿Qué es la Técnica de Shadowing?

Shadowing es una técnica de aprendizaje de idiomas respaldada por la ciencia, desarrollada originalmente para la formación de intérpretes profesionales y popularizada por el políglota Dr. Alexander Arguelles. El método es simple pero poderoso: escuchas audio en inglés nativo y lo repites en voz alta de inmediato, como una sombra que sigue al hablante con solo 1-2 segundos de retraso. A diferencia de la escucha pasiva o los ejercicios de gramática, el shadowing obliga a tu cerebro y músculos de la boca a procesar y reproducir simultáneamente patrones de habla reales. Las investigaciones muestran que mejora significativamente la precisión de la pronunciación, la entonación, el ritmo, el habla conectada, la comprensión auditiva y la fluidez al hablar, convirtiéndola en una de las metodologías más efectivas para la preparación del IELTS Speaking y la comunicación en inglés en el mundo real.
