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.

What’s the weather?
In today’s technology-laden world we can start the day by simply asking our digital assistants “What’s the weather going to be today?” But weather goes far deeper and can be far more interesting than just whether or not you are going to put on a jacket today. We are going to explore the fascinating world of weather and show fun ways you can interact with the weather every day!
Let’s start with what the weather is. Weather describes the conditions outside at any given time. This usually includes the temperature, if there are any clouds present and, the reason most of us check it, will there be any rain?
Let’s start with temperature. The temperature can tell you how hot or cold a day is going to be. In the United States we use the Fahrenheit scale. This scale is hundreds of years old and was based on human beings internal temperature being roughly 90 degrees fahrenheit. A thermometer is the device used to measure temperature. As technology improved and thermometers advanced we learned that a human body’s internal temperature is actually closer to 98 degrees fahrenheit than the 90 degrees that the scale was built off. The rest of the world, excepting Liberia and the Cayman Islands, uses the celsius scale. This scale is based on the freezing and boiling temperatures of water.
One of the questions students always ask me is “If I am 98 degrees then why does a 98 degree day feel so hot?” The answer to this question is all about the skin. When we take our temperature we usually put the thermometer in our mouth to get our internal body temperature. If you were to take the temperature of your skin it would be closer to 70 degrees. That is why we feel comfortable around that temperature and get hot or cold if the temperature goes above or below 70.
Our next big concern with weather is what is going on in the sky. Clouds can quickly turn a hot morning by the pool into a chilly afternoon. Clouds are made of evaporated water. As the sun heats oceans, lakes and even pools some of the water heats up enough to evaporate. This evaporation is what causes rain puddles to disappear when the sun comes out. The water warms and rises into the air until it reaches the colder parts of our sky. When the water cools down it condenses or sticks together, just like on a cold mirror in the bathroom after you take a hot shower. As the water sticks together it can form all kinds of different clouds. If enough of this water sticks together it can become too heavy and fall back down to earth.
Any water coming out of the sky is called precipitation. Precipitation can come in many forms. One of the most common forms is rain. As the tiny drops of water in clouds collect they will form raindrops, these drops fall through the cloud picking up more and more water on their way down. Sometimes raindrops can be small and misty, other times the drops can be huge and hit with a splash. If the temperature is cold enough these raindrops can freeze on their way down causing freezing rain, sleet and hail. If the cloud is cold enough the water freezes into ice crystals which fall as snow.
How can we interact with the weather? Grab a thermometer and head outside. Start by trying to guess what the temperature is before checking the thermometer. Set the thermometer down in a sunny spot and a shady spot. How do the temperatures differ when they're in the sun?
Make your own predictions. Head outside in the morning, look at the sky and guess or measure the temperature. What do you think the weather is going to be? Will there be rain, or is it going to be sunny all day? Write your predictions down and check to see if you were correct later on. Pretty soon you will be predicting the weather like a true meteorologist. (Scientist who studies the weather, not meteors.)
You can also build a rain gauge. A graduated cylinder works perfect but a cylindrical cup will work just fine. Put out your rain gauge before the rain and then measure how much rain fell by putting a ruler in the cup after. The number of inches of water in your cup is the number of inches of rain that fell during the storm. Did you know every 1 inch of rain would be 1 foot of snow if the weather was cold enough?
Weather is also not a local occurrence. A rainstorm in your area most likely formed hundreds or thousands of miles away. Many of these storms, like hurricanes, follow predictable paths. Using sites like ventusky.com you can track these storms as they begin forming hundreds of miles out in the ocean. You can also get a more global look at weather patterns.
We make a lot of decisions based on the weather. Most students just look at the weather as something that happens without spending a lot of time really thinking about what causes rain or where snow storms come from. Take some time with your student to observe, predict and even measure your local weather.

Our Sun, the most important star in our sky. All living things on the Earth depend on the sun to warm the earth, provide light during the day, and for changing seasons and differing climates around the world. The Earth's rotation, day and night as well as seasons can be an abstract idea for children, but Kids Academy has created this video to bring these concepts to life for all learners. Children will gain a better understanding of how our Sun and Earth function together and the effects it has on our everyday life as well as long term effects such as seasons.
The earth's rotation (how it spins), revolution around the sun, and the connection to day/night and seasons are animated and explained in this engaging video. Connections are made between the Earth’s rotation around the Sun and day and night. The tilt of the Earth on its axis affects the angle that its light hits Earth and therefore warms the earth. This means that the tilt of the earth affects climate in different parts of the world. For example, the sun's light does not ever directly hit the North and South Pole, so these habitats are very cold because they never get enough of the Sun’s energy to warm them up. On the other hand, the equator is right in the middle of the Earth, so it gets a lot of our Sun's light, and it is always hot there. The Sun impacts our daily lives in many different ways from when we get up and go to sleep, to the holidays we celebrate and activities we partake in.

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
