Problems in Esl

Introduction to problems in esl:

ESL stands for English as second language spots in math problems. Research shows that students who build up proficiency in math in their primary language will have greater achievement in becoming proficient in math in the second language. Whenever possible, it is a superior strategy to teach math skills in ESL students’ main language for their great success and at the same time that they are learning these concepts in English. Math problems while presented in English can be discussed in the home language in order to enlarge knowledge acquirement in the primary language.

Problems in Esl - Example Problems::

The most important thing is to simplify the language, not the math, of the story problems. Use short simple sentences, rather than complex sentences by adding conjunctions.

Example 1:

Ben had 15 books and he gave 10 of them to his friend Tom.

Solution:

Ben had 15 books. He gave 10 to Tom.

Example 2:

John has 8 cookies and Steve has 12 cookies. How many more cookies does Steve have than John?

Solution:

John has 8 cookies. Tom has 12 cookies. Who has extra’s? How many extra’s?

Example 3:

A mathematical problem in math notation:

Solve for G:

G = S - 20

G + 5 = (S + 5)/2

might be presented in a word problem as follows:

George is twenty years younger than Sarah, and in five years' time he will be half her age. What is George age now?

Solution:

The solution to the word problem is that George is 15 years old. While the answer to the math problem is G = 15 (and S =35). Understanding Common Logarithm is always challenging for me but thanks to all math help websites to help me out.

Problems in Esl - Practice Problems::

Word problems commonly include math questions, where facts and information about a certain system is given and a student is required to develop a model.

Problem 1:

Daisy has $5 and she use $3 to buy some that she needs. How much amount does she have now?

Problem 2:

A mathematical problem in a math notation:

The following problems are used to learn the concepts and we can apply the concept to other same kind of problems.

Problem1) Solve for x , 2x+5y+12 = 42, where y =2

Solution:

Here we need to find the value of x.

Apply the y value in the above equation, we get

2x+5y+12 = 42

2x+5(2) +12 =42

2x +10 +12 = 42

2x +22 = 42

Add -22 on both sides, we get

2x +22 -22 = 42-22

2x = 20

Divide by 2 on both sides, we get

2x/ 2 = 20/2

x = 10.

The value of x =10

Problem2) Find the area of a circle whose radius is 9 cm

Solution:

Here we need to find the area of a circle

Area of circle = `pi` r2

Here pi = 3.14 , r =9cm

Apply those values in the formula,we get

Equality Symbol

Introduction to equality symbol:

Equality expression allows all the operation in mathematics. The equality should be denoted by a symbol ‘=’.

Example: p = q. It represents that the terms at both sides are equal which is represented by a symbol ‘=’. We can do all the arithmetic operations at this equality expression without change the meaning of equality. This equality is used for solving the equations.

Properties of Equality Symbol:

The properties of equality symbol are,

Addition property of equality symbol
Subtraction property of equality
Multiplication property of equality
Division property of equality
Addition property of equality:

It states that the addition of a number at equality cannot change the meaning of equality symbol.

Example: p + q = r + q

Subtraction property of equality:

The subtraction of a number at equality cannot change the meaning of the equality symbol

Example: p – q = r – q

Multiplication property of equality symbol:

The multiplication of a number at equality cannot change the meaning of equality symbol.

Example: p . q = r . q

Division property of equality:

The division of a number at equality cannot change the equality symbol.

Example: p/q = r/q

Example Problems to Equality Symbol:

Example: 1

Solve: 5 + b = 25

Solution:

Given 5 + b = 25

Subtract a number 5 at both sides for getting unknown value b.

5 + b – 5 = 25 – 5

b = 20

To check:

5 + 20 = 25

25 = 25

Answer: b= 25

Example: 2

Solve: n - 22 = 69

Solution:

Given n - 22 = 69

Add a number 22 at both sides for getting unknown value n.

n – 22 + 22 = 69 - 22

n = 47

Example: 3

Solve: 7 p = 147

Solution:

Given 7 p = 147

Divide a common number 7 at both sides for getting p

`7/7`  p = `147/7`

p =21

The Equation Y Kx is Called

Introduction to the equation y  kx is called:
If  x and y are the two variables, y is directly proportional to x and there is a constant k exists. (Constant k is always not equal to zero). This is called as direct proportionality. It is denoted as y ∝ x.

If we want to remove the proportionality symbol, then we use the constant k. It also can be written as y = k x.

where,  k =` y / x` .   k is called a proportionality constant (or) constant of proportionality. Now, we are going to see some of the problems on the equation y  kx is called an direct proportionality. Having problem with Addition of Polynomials keep reading my upcoming posts, i will try to help you.

Example Problem Related to the Equation Called as Y Kx:

Example problem 1:

Let us assume the variable y is directly proportional to x. Given y = 60 and x = 20. Write an equation which is called as a direct proportionality that relates x and y.

Solution:

Given y = 60 and x = 20

Direct proportionality, y ∝ x

It also can be written as y = k x

Substituting the given x and y values in the above equation,

60 = k * 20

Divide by 20 on both sides of the equation

`60 / 20 = (20k) / 20`

k = 3

Substitute the value of k in the equation y = kx.

So, the equation is y = 3x. I have recently faced lot of problem while learning greatest integer function, But thank to online resources of math which helped me to learn myself easily on net.

Additional Problem Related to the Equation Called as Y Kx:

Example problem 2:

Let us assume x and y are the variables. If y varies directly as x and the value of y = 66 when the value of x = 11.

1)      Find the value of proportionality constant

2)      Calculate the value of y when x = 22

3)      Calculate the value of x when y = 33

Solution:

1) Given y = 66 and x = 11

Direct proportionality, y ∝ x

It also can be written as y = k x

Substituting the given x and y values in the above equation,

66 = k * 11

Divide by 11 on both sides of the equation

`66 / 11 = (11k) / 11`

k = 6

So, the proportionality constant k =6.

2) Substitute the value of x = 22 and the proportionality constant k = 6 in the equation y = k x

y = 6* 22

y = 132

So, the value of y = 132.

3) Substitute the value of y = 33 and the proportionality constant k = 6 in the equation y = k x

33 = 6 x

Divide by 6 on both sides of the equation

`33 / 6 = (6x) / 6`

x = 5.5

So, the value of x = 5.5.

Practice Problems Related to the Equation Y Kx:

1) Let us assume the variable y is directly proportional to x. Given y = 26 and x = 13. Write an equation which is called as a direct proportionality that relates x and y. (Answer:  y =  2x).

2) Let us assume the variable y is directly proportional to x. Given y = 50 and x = 10. Write an equation which is called as a direct proportionality that relates x and y. (Answer: y = 5x).
