Phonics teaches learners that letters represent the sounds in the English language. Phonics provides the tools needed to read and spell words correctly. To be successful in phonics, a solid foundation of learning the alphabet and each letter’s sound is essential.

To begin young learners must first learn how to identify each letter. Then the student learns that each letter has one or more sounds. The letters put together to form words. Reading words phonetically allows children to decode unfamiliar words independently.

Children that read words primarily by sounding them out read more at an earlier age, read more fluently and overall have reading success.
In preschool and kindergarten, children will learn the alphabet and each letter’s sound(s). Visual and auditory learners benefit from teaching materials such as fun videos to aid the learning process.

Children can learn about the letter Y with this fun and endearing video. The video opens with an animation that shows the letter Y and names and then draws the letter. The scene then changes to a group of yaks that are yawning. The student learns that the words “yawn” and “yak” begin with the letter Y and the Y sound repeats many times.

The student repeats the letter Y sound and each word. The snowy and cold scene shows a very cold cat that is shivering. The yak then knits a sweater for the poor cat and the viewer says the word “yarn” and repeats the Y sound. Learning about letter Y has never been so much fun!
The alphabet for kids is a necessary skill and lays the foundation for reading success.

This video identifies the letter Y, repeats the letter Y’s sound and gives the student three words that have the Y sound. The students associate the letter and it’s sound to the words in the video and remember the letter and sound more easily. This video is a great tool to learn phonics in the school or home classroom.

Hypothesis Testing - Solving Problems With Proportions Teacherflix 13 Views • 2 years ago

This statistics video tutorial explains how to solve hypothesis testing problems with proportions. It explains how to calculate the sample proportion and the z-test statistic and how to compare that with the critical values in order to determine whether or not if you should accept or reject the null hypothesis at a specified confidence level or significance level.

The Simplest Math Problem No One Can Solve - Collatz Conjecture Teacherflix 9 Views • 2 years ago

The Collatz Conjecture is the simplest math problem no one can solve — it is easy enough for almost anyone to understand but notoriously difficult to solve. This video is sponsored by Brilliant. The first 200 people to sign up via https://brilliant.org/veritasium get 20% off a yearly subscription.

Hello friends! Welcome to a new Happy Learning video.
Today, we’re going to meet animals that have eight legs, and are a little scary! Today, we’re going to meet.. arachnids!

Same as insects, arachnids are invertebrates and belong to the arthropods. But don’t get confused! Arachnids are part of a different animal group than insects, while insects have six legs, arachnids have eight! Like you can see in these images.

Spiders, scorpions and dust mites are part of the arachnid family, and share a number of characteristics that we need to know.

They have four pairs of articulated legs, they don’t have antennae or wings, but they do have a pair of clamps by their mouth called chelicerae (kelicera) that they use to hold their prey.
A fun fact about arachnids is that they can’t chew, so they swallow their prey by sucking them in. They suck the soft parts as if with a straw. They are carnivores, and spiders and scorpions feed from insects, other arachnids and sometimes small reptiles and mammals.

An Arachnid’s body is divided in two parts: cephalothorax, consisting of their head, and thorax, joined in a single segment, and the abdomen, that can be segmented, or not.

Arachnids breathe through traqueas or pulmonary sacs.
And when they’re born, they look the same as they do when they are adults, but of course, they are much smaller.

Scorpions are the biggest arachnids, the largest ones can measure up to 20cm.
They have huge chelicerae (kelicera) in their heads they use them to grab their prey, before they inject venom with their sting at the end of their tail.

Spiders are the most popular arachnids, but also the scariest. Most of them are venomous, but very few are truly dangerous for human beings. The truth is spiders are astonishing animals.
Also! Apart from being able to produce their famous spider web, they are able to hunt their prey in multiple ways, look look!

Dust mites are the least popular arachnids, because they are so small you can’t see them at a glance, they are microscopic, but what is true is that they’re everywhere!
In every house there are thousands and thousands of dust mites…

Well, now we know a little more about arachnids, the truth is they are very strange and mysterious animals. But, as for everything else, they are important for balance of life, of this marvellous life.

Goodbye friends! See you next time! And don’t forget to suscribe to Happy learning TV.

Hello friends! Welcome to a new Happy Learning video.
Today, we’re going to learn about the human musculoskeletal system, It’s what lets us move around!
The musculoskeletal system, is made up of two systems, the muscular system, and the skeletal system.
The muscular system is the active part of the musculoskeletal system. Muscles are between our bones and skin and they are joined to the bones through tendons. They are elastic organs that can be lengthened, or shortened, causing some body part movement. Us humans, have approximately 630 muscles.
According to the movements that they make, we can differentiate, voluntary and involuntary muscles. Voluntary muscles move only when we want them to and the involuntary muscles are those that move without us realising, like our heart or stomach, that are always in movement.
The skeletal system is made up of all bones and cartilage. The Skeleton gives us our shape, that differentiates us from other living things and allows us to walk, run or jump. Our body has 206 bones and each one of them has their own name. Some of them are, skull, that protects our brain, the spine, that maintains us stable and upright, the jaw, allows us to move our mouths to chew food, Ribs, that protect our heart or lungs and femur, the longest bone in the human body and is found in our legs.
Bones are joined with each other by joints.
They are divided into three groups, depending on their level of mobility:
Immobile or fixed joints, don’t have any mobility, like the ones that join the skull.
Semi-mobile joints, that do have some mobility, but not a lot, like vertebrae (vertebri) in our backs.
Mobile joints, that have great mobility, like our elbow or knee.
Now we’ve got to know a little more about our musculoskeletal system. Now, we need to do plenty of physical exercise to make it work brilliantly and maintain ourselves really healthy.
