Precalculus on Khan Academy: You may think that precalculus is simply the course you take before calculus. You would be right, of course, but that definition doesn't mean anything unless you have some knowledge of what calculus is. Let's keep it simple, shall we? Calculus is a conceptual framework which provides systematic techniques for solving problems. These problems are appropriately applicable to analytic geometry and algebra. Therefore....precalculus gives you the background for the mathematical concepts, problems, issues and techniques that appear in calculus, including trigonometry, functions, complex numbers, vectors, matrices, and others. There you have it ladies and gentlemen....an introduction to precalculus!

Trigonometry on Khan Academy: Big, fancy word, right? Don't be fooled. Looking at the prefix, tri-, you could probably assume that trigonometry ("trig" as it's sometimes called) has something to do with triangles. You would be right! Trig is the study of the properties of triangles. Why is it important? It's used in measuring precise distances, particularly in industries like satellite systems and sciences like astronomy. It's not only space, however. Trig is present in architecture and music, too. Now you may wonder...how is knowing the measurement and properties of triangles relevant to music?? THAT is a great question. Maybe you'll learn the answer from us in these tutorials!

Welcome our new video: Mental Math Strategies and Activities for Kids | Kids Academy

Math strategies and activities for kids are the healthiest activities for kids and their brains. The more they work with math the sharper their minds become. If you can build a strong grip of a child on math at this early age he/she can easily handle the upcoming massive difficult mathematics that waits for them in higher standards.

There are a number of mental math strategies that you can adapt to make your child mathematics strong.

1. Mad minutes
In this strategy, the student will answer as many math questions as possible in 60 seconds. It is a series of daily activities and is uses focused and theme-based math problems. It enables a sharp mind to work quickly. A good practice of this game will train the brain to work quickly and solve problems quickly.

2. Number Talks
This strategy can make add a lot easier for kids. It might not be the perfect way to add but it can help kids to understand the concept on a basic level. For example, if the question is 5+5. So simply you count to 5, then to add next 5, you count the next 5 numbers, that is 6,7,8,9,10. This gives you an answer of 10 so 5+5=10.
This trick can make addition or subtraction very easy for kids.

3. Number songs

Things that rhyme is the easiest to remember that is why you remember even the songs you heard years ago because the rhythm stays in your brain. So why not learn math with rhythm too.

You can make a song or anything in math, just add some words that rhyme with each other and that will help you remember all the steps that you need to perform in a question. As you sing the song you will complete the steps.

So, these were some mental math strategies that you can use with kids to make their math stronger.

Addition and Subtraction by 10 | Teaching Math for First Grade Kids Academy

You are reading this article right now probably because your child is now in grade 2 and he is at that stage where you are struggling hard to educate him about the concept of subtraction and addition. Well, for starters, we know that teaching a child the rudiments of maths is a one daunting and tiring task mainly because there are children out there who just hate maths. Well, if your kid is one of them and if you think he just isn’t interested in learning subtraction and addition then don’t worry because today we are here with some solutions that might work for you. Because at the end of the day, maths is important and you can’t just run away from this struggle.


For starters, if it’s the beginning then we’d suggest you start with the numbers that fall between 1 to 10. Yes, you read that right! You see, if you directly start juggling between numbers 1 - 100 then chances are that your child will get confused and he will lose all the interest he has for maths. So, whenever you are starting, just work on the numbers from 1 to 10 because that way it will be easier for your child to pick the concept of addition and subtraction.

Not only this, in fact, you can opt for Youtube videos because let’s face it, children just love visuals and they would do anything to watch online videos. So, why not use this to teach them about the rudiments of maths? You see the concept of adding and subtracting is a little confusing for your child but if you make the learning process a little more fun, we assure you that you will find some success in it.

So, use videos, play games and read your children some story books that somehow are related to maths and especially addition and subtraction.

Learn all about the layers of the atmosphere.
In this video, I cover the troposphere, stratosphere, mesosphere, and the thermosphere. Each of the layers of the atmosphere is separated by temperature.
Thanks for stopping by MooMooMath. I made a mistake and misspelled "Troposphere" I uploaded a new and correct video and added a little bit more information about temperature and atmospheric pressure.

6 kingdoms of classification in 3 minutesThe 6 kingdoms are
Animal
Plant
Fungi
Protist
Eubacteria
Archaea

The Animalia kingdom is an extremely diverse group of individuals
Some animals are giant, like the blue whale, whereas others are tiny, like an ant Some have complex nervous systems and are very intelligent, whereas others are simpler, like the sponge.
Some common traits
Animals are heterotrophs, which means they eat other organisms for food.
Animals are multicellular, meaning they are made up of more than one cell.
Animal cells are eukaryotic, animal cells contain membrane-bound organelles, or tiny organs, which help the cell undergo certain processes it needs to function.

In addition, animals use the protein collagen to attach cell tissue together.
Finally, animal cells are diploid, meaning each cell has a two pair of chromosomes. One pair is is usually from mom and one from dad
Plantae kingdom contains large trees and flowers. Let’s see what they have in common.
First plants are autotrophs. This means they can get their food from the sun.
Next, they are eukaryotes and contain a cell wall and plants are multicellular

Fungi range from mushrooms to yeast
Some mushrooms are multicellular and others a unicellular
Fungi are eukaryotes and contain a cell wall
Fungi are also heterotrophs
Some fungi are decomposers while others are parasites

Protista
Kingdom Protista has been called the junk drawer kingdom. Protist range from single-cell organisms like euglena to multicellular kelp Some are plant-like, others animal-like, some fungi like
As the catchall kingdom for eukaryotic organisms if it is a not animal, plant, or fungi it is thrown in the protist kingdom it is not surprising that very few characteristics are common to all protists.
Some protists are heterotrophs but others are autotrophs.
Most protists are found in moist environments

Eubacteria single cells prokaryotes which mean they don’t have a nucleus or membrane-bound organelles
Have a cell wall, some move with a flagella
Eubacteria help digest food, make us sick, or help make yogurt

Archaea are prokaryotes like bacteria but are structurally different many handle extremes
Extreme temperatures, extreme salty conditions, or little or no oxygen
