What must be prepared for children who step on to the next grade 2, at this age do not let the parents do not know what that should be required in 2nd grade math.
There are a few things to be prepared to be the best in math in grades 2, material that must be mastered in grade 2 about math is still about addition, subtraction, multiplication and division. So basically prioritizing children must master the system count the steps that must be taken are:

     If the child needs to enter in at the specialist tutoring math because math is the technique requires a relatively long time so it must immediately begin making decisions, it does not mean menomor two other subjects besides math lessons than can be read or recited (by mother ).
       Do not have an idea to incorporate the principles of tutoring to be that expensive does not mean it's cheap is not good, it's a lot of evidence that was not expensive to lift children's achievement to be the winner.
     In the second year, the parents immediately practice the multiplication of the species number in a week this has been done the way the tutor / teaching professionals in the fields of mathematics, as for the type of numbers that I mean for example, the number 9 is multiplied by 1 to 9 for one week is not replaced by other numbers. After the children have memorized one week then the next target is the number to another and apply the same way drill continues in one week.

So tips on how to master the math grade two, hopefully we can help to improve the intelligence of children, This Smart Math Simple Solution Methods.

Smart Way Mathematics

The Smart Way to Early math is a step that must be taken by many older people especially the young mothers who always want their children so smart math since kindergarten age , a variety of ways such as looking for an agency pursued ranging from A to Z of financially affordable to the high level .Basically my goal is just a clever math or general subjects but math is a top priority because of what ? , Indeed mathematics requires fast and precise counting this is a long process because the child had often heard a number of points and a lot of practice , as for some Tips on how clever mathematics from an early age as follows :

    In the golden age of children is very high level of intelligence seraph brain power , at this age an important role for parents to air an effort to provide guidance began writing numbers that can not be made better with the help of number of points , then the child is asked to be the point thicken numbers - point proficiency level this is done with the sorts of numbers such as the number 2 performed many times and then figure be changed so that children write numbers memorized .
    The second process is the task seoang why mothers should mother again because math is better when presented in the native language at this step mother prepare objects or toys that will be better shaped figure objects in the form of 3-dimensional shape earlier figures are colorful , in the form of 3 -dimensional will create a memory in a child's imagination .
    After the third process can write numbers next step is to learn simple numbers do not add up over 10 because it is training or raising the left brain ( functions writes , menhitung ) is also useful in addition to enlarged right brain ( function for air imagination ) . since the right brain for imagination then air the parenting skills needed to make a story about dealing with a sum of not more than 10 .
Example : Anto has 2 marbles are then given 5 marbles father so how marbles Anto now ? . Note : This example is presented in the story just does not need to be written so kids just answered only

Formula Math Perimeter of a Circle

Perimeter is the distance around a closed figure and is typically measured in millimetres (mm), centimetres (cm), metres (m) and kilometres (km). These units are related as follows:
10 mm = 1 cm
100 cm = 1 m
1000 m = 1 km

The word 'perimeter' is also sometimes used instead of circumference.
If we know the radius
Given the radius of a circle, the circumference or perimeter can be calculated using the formula bwloe:

Perimeter (P) = 2 · π · R
where: R is the radius of the circle π is Pi, approximately 3.142
If we know the diameter
If we know the diameter of a circle, the circumference can be found using the formula
Perimeter (P) = π · D
where: D is the diameter of the circle π is Pi, approximately 3.142
If we know the area
If we know the area of a circle, the circumference can be found using the formula:
Perimeter (P) = √(4 · π · A )
where: A is the area of the circle π is Pi, approximately 3.142



Smart Math Example 1:
A circular flower-bed has a radius of 9 m. Find the perimeter/circumference of the flower-bed.
Smart Solution:

P = 2 · π · R
P = 2 · 3.1416 · 9
P = 56.5487 cm
So, the perimeter/circumference of the flower-bed is 56.5487 m.



Smath Math Example 2: Find the perimeter of the given circle whose diameter is 4.4 cm.
Smart Solution:
Given that:
Diameter of the circle (D) = 4.4 cm.

We know the formula to find the perimeter of the circle if the diameter is given, namely π·D.

Substitute the diameter 4.4 and Pi value as 3.14 in the above formula.
Perimeter = (3.14)(4.4) = 13.82
Therefore 13.82 cm is the perimeter of the given circle.

Smart Math Example 3: If the radius is 11.7 cm. Find perimeters (circumference) of the circle.
Smart Solution:
Given that:
Radius (r) = 11.7cm
Perimeter (circumference) of circle P = 2 π r
Substitute the r value in the formula, we have:

P = 2 x 3.14 x 11.7
P = 79.56 cm
Thus, the perimeter of the circle is 79.56cm

Smart Math Example 4: Find the perimeter and area of the circle, if the radius of the circle is 8cm.
Smart Solution: We have given the radius, which is 8cm. So, by using the formula of the perimeter of the circle, we have:

P = 2πr
P = 2×3.14×8
P = 50.24 cm
And for the area of the circle:-
A = π r2
A = 3.14×(8)2
A = 200.96cm2

Smart Math Example 5: The wheel of a bullock cart has a radius of 6 m. If the wheel rotates once how much distance does the cart move?
Smart Solution:
If the wheel rotates once, the cart will move by a distance equal to the perimeter of the wheel.
Step 1:
P = 2πr
P = 2× 3.14× 6 = 37.68 m
Thus, the bullock cart moves 37.68 m in one revolution of the wheel.

That is Formula Math Perimeter of a Circle

Formula Math Perimeter of a Rectangle

Formula Math in rectangle, the distance around the outside of the rectangle is known as perimeter. A rectangle is 2-dimensional; however, perimeter is 1-dimensional and is measured in linear units such as feet or meter etc.The perimeter of a rectangle is the total length of all the four sides.
Perimeter of rectangle = 2L + 2W.
Math Example 1 : Rectangle has the length 13 cm and width 8 cm. solve for perimeter of rectangle.
Smart Solution:
Given that:
Length (l) = 13 cm
Width (w) = 8 cm

Perimeter of the rectangle = 2(l + w) units
P = 2(13 + 8)
P = 2 (21)
P = 42

Thus, the perimeter of the rectangle is 42 cm.

Math Example 2: If a rectangle's length is 2x + 1 and its width is 2x – 1. If its area is 15 cm², what are the rectangle's dimensions and what is its perimeter?

Smart Solution:
We know that the dimensions of the rectangle in terms of x:
 l = 2x + 1
w = 2x – 1

Since the area of a rectangle is given by:
A = l * w

We can substitute the expressions for length and width into the equation for area in order to determine the value of x.

A = l * w
15 = (2x + 1) (2x -1)
15 = 4x² – 1
16 = 4x²
x = ±2

 Note that the value of x must be positive and therefore in our case, the value of x is 2. And now we have:
l = 5 cm
w = 3 cm
Therefore, the dimensions are 5cm and 3cm.

Now, substituting these values in the formula for perimeter, we will get
P = 2l + 2w
P = 2(5)+2(3)
P = 10+6
P = 16 cm

Math Example 3: Find the area and the perimeter of a rectangle whose length is 24 m and width is 12m?
Smart Solution:
Given that:
length = L = 24m
width = W = 12m

Area of a rectangle:
A = L × W
A = 24 × 12
A = 188 m²

Perimeter of a rectangle:
P = 2L + 2W
P = 2(24) + 2(12)
P = 48 + 24
P = 72 m

Math Example 4: Find the area and perimeter of a rectangle whose breadth is 4 cm and the height 3 cm.
Smart Solution:
Area = b×h = 4×3 = 12 cm².
Perimeter = 2(b) + 2(h) = 2(4) + 2(3) = 8 + 6 = 14.

Math Example 5: Calculate the perimeter of the rectangle whose length is 18cm and breadth 7cm
Smart Solution:
Given that:
L = 18 cm
B = 7 cm

Perimeter of rectangle = 2(length + breadth)
P = 2 (L + B)
P = 2 (18 + 7)
P = 50 cm


Math Example 6: Find the perimeter of rectangle whose length is 6 inches and width is 4 inches.
Smart Solution:
P = 2(L + B)
P = 2(6 + 4)
P = 20 in

Math Example 7: A boy walks 5 times around a park. If the size of the park is 100m by 50m, find the distance the boy has walked. If he walks 100m in 5 minutes, how long will it take for him in total?
Smart Solution:
Given that:
Length = L = 100m
Width = W = 50m
Rounds = 5
Time per 100m = 5minutes.

Perimeter of the park:
P = 2 L + 2 W.
P = 2 × 100 + 2 × 50
P = 200 + 100
P = 300 m

Total distance walked = 5 × Perimeter of the park.
= 5 × 300
= 1500 meters

Total time taken = Total distance walked × time taken to walk 1m.
= 1500 × 5/100
= 75 minutes or 1hr 15minutes
