In this video we're going to talk about fractions
2
and I want you to understand the concept of a fraction using visual illustrations.
3
So let's say if we have a circle.
4
Let me draw a better looking circle.
5
And let's split the circle into two equal parts.
6
Now I'm going to shade only one portion of those two parts.
7
So what fraction of the circle is shaded?
8
So there's two parts of the circle and only one of those two parts is shaded.
9
So we could say that one half of the circle is shaded.
10
Now let me give you another example.
11
Let's say if I have a circle and I split it into four equal parts.
12
And I'm going to shade this part of the circle.
13
So what fraction of the circle is shaded?
14
So there's four equal parts of the circle, and three of those four parts were shaded.
15
So three-fourths of the circle is shaded.
16
Now let me give you another illustration.
17
So let's say we have a circle again.
18
And this time, I'm going to divide the circle into eight equal parts.
19
So what fraction of the circle is shaded?
20
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.
21
So three-eighths of the circle is shaded.
22
And so hopefully these visual illustrations help you to understand a concept of a fraction, which is basically a portion out of a whole.
23
Now here's another example for you.
24
So let's say we have a rectangle.
25
And it's broken up into seven congruent parts.
26
Now granted, my drawing is not perfect, but we'll make it work.
27
And let's say three of those parts is shaded.
28
What fraction of the rectangle is shaded and what fraction is not shaded?
29
So there's seven equal parts, and three of those seven parts are shaded
30
so we could say three-sevenths of the rectangle is shaded now
31
out of this total seven parts four of those seven parts is not shaded
32
so four-sevenths of the rectangle remains unshaded or not shaded Now,
33
let's look at another example.
34
So let's say we have a square.
35
And we're going to break up the square into a total of eight parts.
36
What fraction of the square is not shaded?
37
And what fraction is shaded?
38
So out of the eight parts, five of those parts is shaded.
39
So we can say that five eighths of the rectangle, or rather, of the square is shaded.
40
Now what fraction is not shaded?
41
out of the total eight parts, three parts is not shaded.
42
So hopefully these visual illustrations help you to solidify the concept of a fraction.
43
So here's a practice problem for you.
44
Draw a circle and shade only two-fifths of the circle.
45
So feel free to pause the video.
46
So here's a circle, and we'll need to break it up into five equal parts.
47
So that's going to be one, we'll say two, three, four, and five.
48
So once you split it into five parts, all you need to do is shade two of those five parts.
49
And so in this case, two-fifths of the circle has been shaded.
50
And so that's basically it for this video.
51
So now you understand fractions with circles and squares and rectangles.
52
So that's basically it for this video.
53
and if you need help with adding or subtracting fractions
54
or even multiplying
55
and dividing fractions I'm going to post a few links in the description section of this video
56
so you can take a look at that when you get a chance.
57
Thanks for watching.

Sobre esta lição

Nesta lição, você vai praticar conceitos de frações em inglês, usando ilustrações visuais para entender como descrever partes de um todo. Além de aprender termos específicos, você vai treinar a pronúncia e a fluência por meio de exercícios práticos, como o shadowing, essenciais para a prática de conversação em inglês.

Vocabulário e frases-chave

  • Fraction (Fração)
  • Shaded (Sombreado)
  • Equal parts (Partes iguais)
  • Portion (Porção)
  • Unshaded (Não sombreado)
  • Two-fifths (Dois quintos)
  • Three-eighths (Três oitavos)

Dicas de prática

Para melhorar a pronúncia em inglês e a fluência, use a técnica de shadowing (ou shadow speak). Repita as frases do vídeo imediatamente após ouvir, imitando o tom, a velocidade e a entonação. O vídeo tem uma velocidade clara e pausada, ideal para iniciantes: pratique frases como "one half of the circle is shaded" ou "three-sevenths of the rectangle is shaded" até que a pronúncia fique natural.

Use um shadowing site para gravar sua voz e compará-la com a do vídeo, ajustando detalhes como a ênfase em palavras como "equal" ou "total". A prática diária, mesmo por 10 minutos, ajuda a internalizar os termos e a estrutura das frases, essenciais para a prática de conversação em inglês. Lembre-se: a chave é a repetição constante!

O que é a Técnica de Shadowing?

Shadowing é uma técnica de aprendizado de idiomas com base científica, originalmente desenvolvida para o treinamento de intérpretes profissionais. O método é simples, mas poderoso: você ouve áudio em inglês nativo e repete imediatamente em voz alta — como uma sombra seguindo o falante com 1-2 segundos de atraso. Pesquisas mostram melhora significativa na precisão da pronúncia, entonação, ritmo, sons conectados, compreensão auditiva e fluência na fala.
