Ideas to get triangular prism knowledge!!

What type of solid a triangular prism is?
A triangular prism is a three dimensional shape having 5 faces. For example; a camping tent is a triangular prism, a wedge is another example of the solid. 

Students can get all about a triangular prism by keeping three points in mind; the fundamentals, the surface area and the volume of a triangular prism In this post we will research all these aspects of a triangular prism one by one.

First grade is the time while three dimensional shapes are introduced to kids along with an introduction to triangular prism. In following step, kids learn all about the basics of these solid shapes, such as how they look like or how their names are derived.

If we talk about faces, the two faces are triangular (because of these two parallel triangular faces, the name of shape is triangular prism) and the rest of the three faces are rectangles. Students require to recognize about edges of a solid and an edge is formed whenever two faces meet; there are nine edges in case of a triangular prism. 

There is another basic term known as the vertex of solids, there are six vertices for each triangular prism and a vertex is the point or sharp corner where three edges of the solid contact. The net of the solids can be alternative basic term affiliated to each solid including this one as this can be very advantageous to get the surface area of the solids.

Surface area of any solid can be defined as the sum of areas of all the faces of the solids; note that the faces of the triangular prism are triangles and rectangles. In case of the surface area of the prism, to experience how get the area of a rectangle and a triangle is the important point. 

As kids want to obtain area of two triangles and three rectangular faces of the triangular prism. It is extremely recommended that kids recognize how to trace the net of a triangular prism to discover its surface area. 

A net helps to visualize each face separately and discover their areas without difficultly, and these areas can be added to discover the surface area of the prism.

Ultimately, the concluding aspect of learning about a triangular prism is to experience about its capacity or volume. Determining volume of a triangular prism or any other solid is a high school math topic and most often grade eight students need to describe how to obtain volume of solids. 

To determine the volume of the prism, the surface area of its base which is a triangle, is calculated and multiplied with the height (length) of the prism (the height of prism is same as the distance between two triangular faces). 

Indeed, the volume is the product of area of base and the height of the prism, look at given image to get it more easily. 

In other words, the volume of the triangular prism is = Area of Base x The height of the prism, 
where height of prism is the distance between its two triangular faces.

As a final world, it can be said that if students know the basic terminology of a triangular prism along with knowledge to determine its surface area and volume, they can do all the math problems related to it. 

Fractions worksheets for preschoolers

This new site contains some cool ideas on fractions worksheets for preschoolers. As half is the most basic fraction, site contains a good idea to explain this to young kids.

When young kids learn to count numbers to tens or higher, they can be given a fun work to recognize fractions. The fractional concept starts at cutting or dividing one whole into two parts or pieces to represent the half, then it builds on further by introducing one third, quarter and other basic proper fractions to kids.

Fractions can also be represented using parts of group of things. But it is always a good idea to start fractions as the parts of wholes.

Once kids got the idea of basic fractions at home they can understand it at school very easily. This makes your kids smarter in math.

Reducing Fractions - Kids Need To Know The Greatest Common Factors

How To Reduce Fractions Into Lowest Terms    

When kids learn fractions, they need to learn simplifying fractions into lowest terms too. Simplifying fractions is also known as reducing fractions into lowest terms. This is done by dividing the numerator and denominator of a fraction by the same number (this dividing number is known as the greatest common factor of the numerator and the denominator)

For example; consider we have a fraction 6/21, in this fraction the numerator is 6 and the denominator is 21. Now, we have to find out if this fraction can be reduced into lowest terms or it is already in its lowest terms.


To see, if a fraction can be reduced into lowest terms; we have to find the common factor of the numerator and denominator of the fraction. In the given fraction numerator is 6 and the denominator is 21. There is a common factor of 3, in 6 and 21, hence we can reduce the given fraction into its lowest terms. 

To reduce this fraction (6/21) into its lowest terms, divide 6 and 21 both by 3 as shown below:

  The new numerator = 6/3 = 2

The new denominator = 21/3 = 7

Hence the reduced fraction = 2/7

 

If the numerator and denominator have no common factor other than one, then this fraction is already in its lowest terms. For example; in case of fraction 3/7, there is no common denominator between numerator 3 and denominator 7 (other than 1). Therefore the fraction 3/7 is already in its lowest terms.


You can learn more about reducing fractions using our fractions worksheets. Math practice makes the kids perfect in math.

What Are Equivalent Fractions?

When two or more fractions have the same value, they are called the equivalent fractions. For example; one of two brothers ate one out of two pieces of pizza, which means this person ate half of pizza, this can be represented as "1/2"

Now there were four pieces of pizza and the other brother ate two pieces out of those four pieces of this pizza. This fraction can be represented as "2/4".

 Now if we see both brothers ate half of the pizza, which means one out of two "1/2" and two out of four "2/4" both represent the same fraction of the whole, and which is half.

Hence the equivalent fractions represent the same part of a whole. Equivalent fractions can be obtained by multiplying and dividing the numerator and denominator of a fraction by the same number.

1. Counting Numbers To Thousands

2. Writing numbers in words and in expanded form up to thousands

3. Rounding numbers to thousands

4. Adding and subtracting with and without regrouping

5. Place value to thousands

6. Types of numbers, such as, even and odd numbers

7. Skip counting by 2's, 3's and 5's

8. Basic geometric shapes in two dimensions and three dimensions.

9. Basic fractions such as basic shapes, colorful charts and models

10. Introduction to times

11. Counting money using money charts and coins

12. Telling times using halves and quarters.

To practice all the above skills use 2nd grade math worksheets which can be printed from many of sites on the net.

How To Learn Rounding Numbers.

2nd Grade Math Worksheets on Rounding Numbers

Kids in 2nd grade math should begin learning the basic rounding. Rounding numbers to tens, to hundreds and thousands is in the basics of rounding the numbers.

Rounding Numbers - Tips For Grade Two Students

In grade two math, kids can start learning rounding numbers. Rounding is very helpful in estimating many big numbers or some times rounding is needed to represent the answer of a problem. Kids in grade two can start rounding numbers from rounding to nearest ten. To learn rounding to nearest tens, kids should know skip counting by tens and place value to tens. Make sure kids are very comfortable with these two skills before starting rounding numbers.

There are following steps for rounding to nearest tens.

1. Ask kids to focus on ones and tens place of the number only (last two digits at far right).

2. Ask the kids to underline the tens digit.

3. Once kids have underlined the tens digit, ask them to look at ones digit.

4. If the ones digit is 0, 1, 2, 3, 4, then keep the tens digit and make ones digit zero if it is not zero already. It is called rounding down.

5. If the ones digit is 5, 6, 7, 8, 9, then ask the kids to add one to the tens digit and make ones digit zero. This is called rounding up.

Example of rounding down: Round 523 to nearest tens.

1. Ones and tens digits are "3" and "2" respectively. Underline the tens digit which is "2" in the given number "523".
2. Now look at ones digit, which is "3" (one of 0 to 4), hence keep the tens digit and make ones digit zero.
3. The rounded down number is "520"

Similarly kids can round to nearest hundreds, by underlining the hundreds digit and deciding to round up or down by looking at tens place digit. Kids in second grade can practice more rounding skills by using 2nd grade math worksheets and practice rounding numbers to make them perfect in this key skill.

Subtraction Worksheets - 2nd grade math worksheets for kids

Introducing Subtraction To Kids Using Subtraction Worksheets  

Kids in grade one need to learn how to subtract one digit numbers. Subtraction is also known as take away and it is very important that kids in elementary grades master this skill.
The basic part of subtracting numbers can be taught to kids using models. Parents can use many things from daily life as models. For example, a bunch of bananas can be used. From kitchen spoons and forks can be used.
There are many more daily life objects which can be used to introduce kids with subtraction. In this presentation we will use the example of bananas.
Get a bunch of bananas from the kitchen and ask the kids to count all of the bananas in it, and consider there are six bananas in the bunch. Now ask one of the kids to pull away one banana and hide it. After that, ask the kids to count bunch of bananas again, this time they will count five bananas in the bunch. Stop there and explain the kids about take away, which means, subtracting number of things and in your example, six take away one is five.
Use lots of examples with other objects from daily life as in the example above. After kids get the idea of take away using concrete examples, the next step is to use subtraction worksheets on basic subtraction with visual shapes. Now you can use pictures of bananas instead actual ones, kids will understand it.
Once kids get the concept of subtraction using shapes, and have learned subtracting numbers by cutting shapes then you can start using numbers instead shapes.
Now get ready to teach your kids subtracting one digit numbers (0 - 9). Following is an example I use to introduce subtraction to my kids and students;
Ask kids to find "5 - 2"
Solution: To do this ask kids to draw five lines as shown below:
/ / / / /
Out of these five lines, now ask kids to erase or cut two lines ( because two is getting subtracted from five) as shown below:
/ / /
Now there will be only thee lines left as shown above, ask kids to count the remaining lines to get their answer, which is three.
Finally ask them to write the subtraction fact as shown below:
"5 - 2 = 3"
Similarly, repeat all the one digit subtraction facts with kids many times, until they are very good at it. Keep it up until they start doing it using their memory without drawing lines and cutting or erasing them.
You can use subtraction worksheets for extra practice and to teach basic subtraction to your kids. Soon, you will find your kids with very strong subtraction skills.

Soon there will be more tips on 2nd grade math and we are updating our site for 2nd grade math worksheets on a regular basis. Parent can print more math content for kids in grade two at our site.

Best Regards.

Fractions Worksheets

Fractions are one of the very important math segments. Kids have to understand them from the core to succeed in mathematics.

As math is a subject which needs lots of practice to learn hence fractions too need tremendous amount of practice using fractions worksheets and other fraction exercises from the text books or workbooks.

To start learning fractions it always a good idea to start from the basics such as equivalent fractions, reducing fractions into lowest terms and then comparing fractions to dividing fractions and mixed numbers.

Care should be taken not to practice hardest fractions worksheets in the beginning but it is always a best practice to start from the basic fraction worksheets and build your knowledge base. This is the key to master your fraction skills.

So, bottom line is to have some fractions worksheets and start practicing your fractions today. Make sure you master the basic fractions first before you move on to higher fraction topics such as adding fractions or multiplying fractions.

Cool math 4 kids - How to represent a fraction

How fractions are represented, or in other words how do we write the fractions?

To represent fractions, mathematicians named the following three things:
1. Numerator
2. Denominator
3. Solidus or Vinculum

Explanation of all three is given below:
1. Numerator: Numerator is the number of parts of whole are considered or asked in the given situation. Numerator is always at the top of the fraction. In the pizza example, we are considering how many pieces (parts) of pizza each member got, which is ―one piece‖ and is our numerator for the fraction.

2. Denominator: Denominator is the number of total parts in the whole. Denominator is always written at the bottom of the fraction. In our example one whole pizza is cut into three pieces (total pieces of a whole), so the denominator for the fraction is three.

3. Solidus or Vinculum: Solidus or vinculum is a line between the numerator and denominator. This line is never called by the above names in daily life mathematics. Most often this line is called the fraction line, or fraction bar, or simply over.
