Let's dig further into fractions addition with today's presentation on adding fractions and mixed numbers. Mixed numbers are made up of a whole number and and a proper fraction (see my previous post on mixed numbers and improper fractions). Also below is another worksheet on understanding improper fractions and mixed numbers:
Now let's start to explore how to add fractions and mixed numbers. Below is the first lesson on the concept which is very much self explanatory and easy to understand the concept:
Poly means “many” and -nomials means “terms”.
We can define a polynomial as an algebraic expression with many terms written together using addition, subtraction and multiplication and non negative integer exponents.
Some examples of polynomials are given below:
Basic terminology associated with polynomials:
Variables: The unknown quantities which can be known under different conditions and can have difference values depending upon the conditions.
For example; number of cars in a mall's parking lot, is a v

This post is to encourage the parents with young kids in grade two and three to teach addition to their kids. You can find all the lesson plans and practice sheets to teach addition to your kids on your own which will be a great aid to boost your kids' math knowledge and confidence at a very very young age.
Below is the first most basic lesson which uses counters to introduce basic addition to young kids:
You can visit the following page of my site to print all level addition worksheets and lessons for your kids so that they never
A ring or a washer is a combination of two circles one inside thee other. So we have to deal with two radii and hence to find areas of both the circles. Then subtract the area of smaller circle from the larger ones to get the area between both the circles with is actually the area of the ring or washer.
In the picture given given above we can find the area of the washer as shown below:
Area of smaller circle:
Given radius for the smaller (inner) circle r = 3 cm
Area of smaller circle = pi x radius x radius = 3.14 x 3 x 3 = 3.14 x 9 = 28.26 sq.cm
Hence the area of the inner circle is 28.26 square centimeters.
Area of larger circle:
Given radius for the larger (outer) circle is R = 5 cm
Area of the larger circle = Pi x radius x radius = 3.14 x 5 x 5 = 3.14 x 25 = 78.50 sq.cm
Alan Green is a
Shakespeare Authorship scholar (and Composer, Pianist, Author) who discovered twelve of the world's most significant math constants (as well as the precise geographical coordinates of the Great Pyramid!) within the punctuation of the Sonnets title page.
I stumbled across the video below via this /r/holofractal thread.
Given the side length of the square = 12 inches
Diameter of the circle = Side length of the square = 12 inches
Radius of the circle = Diameter ÷ 2 = 12 ÷ 2 = 6 inches
Now area of the circle " A" = pi x radius x radius = 3.14 x 6 x 6 = 3.13 x 36 = 113.04 square inches
But there is another question in the given problem asking us to find the area between the circle and the square boundaries (this is the green shaded area in the diagram). To do this; follow the given steps below:
You give blindness
So I cherish
My last view
The sunset's cue
Winter will not
On liquid plates
And wide waves
The land's cupped hands
Scooped my kayak in a pond
Grey matter greens
Patched the visual lawn
She ran from her cabin
Up to the white yellow tent
So I wouldn't know
Which way she went
Given the gift of gab
And glorious execution
The knife cuts a gaze
Off from its munition
You transmit texts
And your workers follow
Orders to spy
On the wandering fellow
With his sloped step
Occurs at aisle zero

Circle is a round two dimensional shape, very often encountered in our daily lives. Examples of a circle are bracelets, ring, washers, popcan lid and dining plates.
All the basic terminology about a circle is very well explained in the image below:
Mathematical Definition Of A Circle
Mathematically, a circle is a locus (or path) of all the points, whose distance from a fixed point remains fixed.
Many students take this definition as very cumbersome.
Let’s simplify the above words by taking an example of a cow tied to a pole with a rope and moving around the pole. What do you think the shape of the path will be?
Now the word “locus of all the points” is cow’s path and the path is always at a fixed distance (the length of the rope) from a fixed point which is the central pole. Hope it will help kids to unders
solve this if you are a genius
Once students understand the idea of division (as explained in previous two posts on division), the next step is to give them some kind of exposure to multi step division problems. Below is a two step long division lesson and worksheets for the beginners.
Ever wonder how to draw a cube very easily or want to draw a nice cube shown below?
Well, its very very easy just follow the steps given in the following sheet and draw and color your own cube:
Similarly you can draw a cuboid which is also known as a rectangular prism:
I've argued, at least with my peers and around my area, that we weren't properly taught what science is (I wasn't properly taught grammar either). There is another area I think that our population (perhaps the world) is weak in as well, and it's basically probabilities.
Here I speak to this weakness in regard to network marketing “schemes” which are basically comparable to our understanding of a pyramid scheme or a Ponzi scheme (although technically different depending on who we ask).
Network marketing or multi-level marketing (MLM) always has the claim that the system is not actually a scam. These “presentations” are accompanied with every single counter to any possible question that a skeptic might ask. In fact, it is far more efficient to just assume that there is no possible question to ask that can't be countered with a “legitimate” answer.
So where is the scam?
The scam is in regard to the scaling, which will always be complex to the extent that it is far better to ascribe potenti
In late grade 4 or early grade 5 kids need to learn long division and I have seen many of them struggle with it . So I prepared a lesson plan for myself to teach step by step very very basic long division to beginners. They KEY WORDS to remember are
DAD, MOM, SISTER, BROTHER (and they all) ROCK.
See the above words in the work shown in the lesson given below:

It was said by Cedric Villani, when John Nash passed away, that not long before the tragedy Nash confided in Villani he had been doing some work that might have significance in regard to Einstein's theory of relativity.
Nash has talked about this in various interviews and he gave a lecture on a special equation that confirms Villani's story.
The further truth is, like Nash's lecture series Ideal Money, the insights Nash shares in regard to cosmology and quantum theory came to him in the 50's (see 3m10s of this video):
Around that time it is said that Nash actually visited Einstein to talk about his insights and that Einstein responded by giving Nash some books to read. One can wonder what literature he was given to study and whether Einstein gave Nash the credit he de
I prepared an easy lesson plan to introduce the concept of division to young kids. Even parents can use this strategy to teach very very basic division idea to their kids. Keep in mind that multiplication is repeated addition and inversely division is repeated subtractions.
Enjoy the lesson below (GO BANANAS):
Tomorrow will post more ideas on solving basic division problems.
Yesterday I did a post on times tables which are the key to multiply or divide the numbers. Today there is another application of times tables and which is the Greatest Common Factor also known as gcf. What is Greatest Common Factor or gcf? It is also known as Greatest Common Divisor gcd.
The greatest common factor (gcf) of two or more given numbers is the greatest factor that exactly divides the given numbers.
How to find the greatest common factor?
To find the gcf of two or more numbers following steps are used:
Find all the factors of the given numbers and then find the common factor which is the greatest.
For example: Let's find the gcf of 18 and 30. We will write all the factors of 18 and 30 as shown below:
18 = 1, 2,
The best way to introduce coins to young kids is to actually give them the change and tell them the value of each coin. But most often in 2nd or 3rd grade math these coins are introduced to the kids. If they had no previous knowledge of the change then it is very hard for them to grasp the concept.
So I urge to parents with young kids, please introduce your kids with all the coins. Take them to the dollar stores and give them change to buy small stuff there.
Once kids have knowledge of all the small coins then the following worksheets can be helpful for the theoretical understanding to solve small problems and conversion of coin value into decimals.
