Class 4 EVS Chapter 3 Tongue and Teeth @kidsknowledgepoint


Our mouth is home to two very important parts: the tongue and the teeth. They play a big role in helping us eat, speak, and even enjoy different tastes! Let’s learn more about how the tongue and teeth work and why they are so important.

1. Teeth – Our Natural Cutters and Grinders

Teeth are hard, white structures in our mouth that help us chew food. Each type of tooth has a special job. Let’s explore the different types:

  • Incisors: These are the sharp, flat teeth at the front of our mouth. We have four on the top and four on the bottom. They help us bite and cut our food, like biting into an apple.

  • Canines: These are the pointed teeth next to the incisors. We have two on the top and two on the bottom. Canines help us tear our food, especially things like meat.

  • Premolars: These teeth are bigger and flatter, located next to the canines. We have four on the top and four on the bottom. They help crush and grind the food into smaller pieces.

  • Molars: These are the biggest and strongest teeth at the back of our mouth. We have six on the top and six on the bottom. They help grind and chew food into tiny pieces, making it easier to swallow.

Fun Fact: Did you know that children have 20 teeth, called milk teeth? As they grow older, these are replaced by 32 permanent teeth!

2. Tongue – Our Taste Buddy

The tongue is a soft, muscular organ inside our mouth. It helps us in many ways, such as:

  • Tasting: The tongue has tiny bumps called taste buds. These taste buds help us sense different flavors like sweet, salty, sour, and bitter. For example, when we eat chocolate, our taste buds tell us it’s sweet, while a lemon tastes sour.

  • Talking: The tongue helps us speak by moving in different ways to create sounds. Try saying "la-la-la" – see how your tongue moves?

  • Swallowing: The tongue pushes food towards the back of the mouth, helping us swallow it easily.

Fun Fact: An adult has about 2,000 to 8,000 taste buds on their tongue!

3. How to Take Care of Our Teeth and Tongue

  • Brush Your Teeth: Brush your teeth twice a day using toothpaste. This helps remove food particles and keeps teeth clean and healthy.
  • Rinse Your Mouth: After eating, rinse your mouth with water to remove any leftover food.
  • Eat Healthy Foods: Eating fruits, vegetables, and dairy products like milk helps keep teeth strong.
  • Clean Your Tongue: Use a tongue cleaner or a soft brush to clean your tongue and remove bacteria.

Conclusion

Our tongue and teeth are important for eating, speaking, and enjoying different tastes. Taking care of them by brushing, rinsing, and eating healthy foods ensures they stay strong and healthy. So, the next time you bite into your favorite food, remember to thank your teeth and tongue for making it possible!

What to Expect in a Grade 2 Math Olympiad Exam Math Olympiad exams for Grade 2 are designed to challenge young students and spark their interest in mathematics. These exams test a range of skills from basic arithmetic to problem-solving and pattern recognition. Here’s a look at the types of questions Grade 2 students might encounter in a Math Olympiad and some tips on how to prepare. Types of Questions in the Grade 2 Math Olympiad Basic Arithmetic Addition and Subtraction: Students are expected to perform basic addition and subtraction operations. For example: "What is 23 + 15?" "If you have 17 apples and you eat 5, how many apples are left?" Multiplication and Division: Though more advanced, simple multiplication and division problems may appear: "What is 4 × 3?" "Divide 12 cookies among 4 friends. How many cookies does each friend get?" Patterns and Sequences Students will need to identify and extend patterns in numbers or shapes. Examples in...

What are Large Numbers? Large numbers are numbers that go beyond the basic hundreds and thousands that students learned in earlier grades. In Grade 4, students typically learn about numbers up to 100,000 or even more, which includes understanding place value, comparing, and working with these numbers in addition, subtraction, and beyond. Why Are Large Numbers Important? Develops Number Sense: Learning large numbers helps students understand the size and value of numbers. They learn how numbers grow, how place value works, and how to read and write them correctly. Real-Life Applications: Large numbers are everywhere in real life! For example, populations of cities, distances between planets, prices of cars, and scores in video games often involve big numbers. Understanding large numbers helps students make sense of these real-world examples. Builds Mathematical Foundation: Mastering large numbers is essential for more advanced math topics like multiplication, division, fractions, and ev...
