LEARNING OBJECTIVES:
The students will be able to:


  1. Identify that digestion starts with teeth and teeth also help us to talk.

  2. Understand that the baby teeth are temporary and fall off by the time they are 12-14 years, permanent teeth are very important and will last our lifetime and not keeping them clean will cause cavities.

  3. Discuss anatomy of tooth and that there are different kinds of teeth and the job they do.

  4. Discover how to maintain dental hygiene and how healthy foods help our teeth and make them stronger.

  5. Investigate as what will happen to our teeth if we do not take care of them.







SPECIFIC Objective: Types of Teeth
The students will be able to:
a) Recognize that there are different kinds of teeth.

b) Infer that these different teeth have unique structure of their own.

c) Identify them with their location and shape inside our mouth

d) Explain how together they help us to eat different types of food.

e) Discover that each of them has a different function, their shape makes them useful for different purposes: molars and pre molars for chewing, canines for tearing, incisors for cutting. There 4 incisors at top and 4 on bottom, 2 canines on top and 2 on bottom, 4 pre molars on top and 4 on bottom, 4 molars on top and 4 on bottom. Also there are 4 wisdom teeth too on each corner, which only erupt when you are an adult

f) Distinguish between different types of teeth

COMMUNITY SERVICE/

As an extension of this lesson, students will conduct a Dental Survey with family, extended family, neighbours and friends to create awareness about dental hygiene. This will help the students understand the importance of dental hygiene even better as they explain and ask questions for the survey. Including servants and maids in the survey is a step forward towards community service.

PERFORMING ARTS

On the basis of the story “Floassie The Tooth” Students will enact a skit in the class which will create an added interest esp in the students who love to act and talk.

VISUAL ARTS

Students will make posters of happy and sad tooth depicting healthy food habits which help to keep our teeth healthy. Also they will make material for their classroom board showing different types of teeth and the tooth structure.

VALUE EDUCATION

Community Service, Creating awareness

LIFE SKILLS

Communication skills, collaboration, knowledge extension




TEACHER FOCUS
Day 1 – Tuning In/Provocation
Gauging prior knowledge of students by generating questions as what do they already know about teeth?
Students write their responses using Padlet so that all students and the teacher can see all the responses at a glance. Can also talk about the tooth fairy to start the discussions.

The questions can be




  1. Why do we need teeth?

  2. Do you know what are carnivores and omnivores?

  3. What are they made of?

  4. How many teeth do you have?

  5. Have your teeth ever fallen out?

  6. Do you know anything about baby teeth and permanent teeth?

  7. Have you noticed teeth have different shapes?

  8. Any idea why they have different shapes?

This discussion will last about 15 minutes. The teacher is able to gauge the existing knowledge they have about teeth.

After this the students will be shown the YouTube video mentioned in the resources. Watching a video always causes some excitement and creates curiosity to learn more.

STUDENT FOCUS
Student Engagement –


  1. Post watching the video, the students to be divided in 4 groups based on 4 types of teeth as Incisors, Canines, Premolars and Molars. 4 types of paper cutouts of the shape of the teeth will be crumpled in a basket and students will pick one cutout each and get into groups who have the same shape, this will also teach them the shape of different types of teeth. (This will form random groups and probability of multiple intelligence group is higher)




  1. As a group they will have to figure out the type of tooth they have the shape of. They will find and collect facts like location of this type of tooth in your mouth and their function and present to the class as a group in the form of a ppt. or a sway which can be put up in the class till this unit is being covered.


3- The introductory video they saw will help them make connections to the shape of paper they have and they can discuss among their group face to face or use skype if not able to meet, to organize the facts they have heard and seen.
Also this will teach them that one type of teeth on their own are incomplete and cannot work but can only work as a team. So it teaches them to collaborate which is key to 21st century learning.

  







Assessment For Learning: Formative Assessment
The teacher will assess the students

  • Are children able to name the main types of tooth (i.e. incisors, canines, premolars and molars)?

  • Are children able to describe the purpose of each type of tooth?

Assignments

  • Tell three facts about teeth.

  • Make a graph showing how many teeth have been lost (extending or expanding knowledge).


Evaluation

  • Was there enough time?

  • Could the students tell me about teeth?

  • Were the students successful or frustrated creating a graph


Recap and Closure: The teacher can organize a circle time to wrap up; it helps to get everyone’s attention. Here the students should be able to tell different types of teeth with different shapes and how they help us to bite, tear, chew, etc.The teacher can close the period with a teeth song(Music) using Song Smith









Specific Objective – Structure of the Tooth
The students will be able to:


  • Recognize different parts of the tooth




  • Infer that all the teeth have same parts/anatomy irrespective of their shape.



  • Identify that there are 2 main parts of any tooth- Crown and the Root.




  • Explain in details about these parts. The hard part on the surface of the tooth is called enamel. Below the enamel is dentin, which is as hard as a bone. Inside the Dentin soft part is called Pulp, which has the nerves and the blood vessels.

  • Discover that the tooth is alive and has a constant supply of blood, is connected by nerves to our nervous system.


Vocabulary - Anatomy, embed, enamel, dentin, crown, blood vessels

Assessment For Learning:

The teacher will assess if the students know

  • The parts of a tooth

  • The functions of each part of the tooth.

  • How our teeth are connected to our nervous system through nerves present inside a tooth.









Specific Objective: Dental Hygiene

The students will be able to:




  • Identify that we need to take care of our teeth.

  • Infer that sweet drinks and sugary food causes tooth decay.

  • Discuss the foods that cause decay.




  • Explain how bacteria like to feed on the sugars left in our mouth to make acid that causes holes in our teeth.



Vocabulary

Dental floss, Flouride, vinegar, Plaque, Decay










Teacher Focus

Tuning In/Provocation
Gauging prior knowledge of students by generating questions as what do they know about Dental care and hygiene?

Start the conversation asking




  • If anyone has visited a dentist.

  • If yes what is the reason?

  • Do you think we can avoid going to the dentist?

  • How can you do that?

  • Can we start eating something different or change our habits?

  • Ask the children how they look after their teeth. Brainstorm some ideas using Padlet created by the teacher on good oral hygiene. Then ask what will happen if we didn’t do all.

  • Ask the children to think what they ate yesterday. Which foods would be most likely to cause tooth decay and why?

  • A picture shown below will be used as provocation too.

This discussion will lead to children coming up with lot of information in bits and pieces. So to put it all together the teacher will show them the video and then children will be given the worksheets for the teacher to assess their understanding.




Vocabulary:
Dentist, cavity, plaque, germs, bacteria, microbes, fungus, virus

Resources

1. Flossie The Tooth Story through MS Power point. Students will enact this as a short skit. This involves

2. YouTube link, which tells about baby teeth, dental hygiene and what foods are good for us.

Student Engagement


  1. Activity- Happy teeth/Sad teeth

Students make a 2 cut outs of a teeth and make one happy and the other will be sad teeth. They will draw or paste pictures as what makes the teeth happy or sad. Sample is attached. This will help them identify what is good and what is bad for their dental health.




  1. To conduct an experiment to see how brushing teeth with flouride toothpaste helps us to keep our teeth clean.

As a provocation, a video is shown of an experiment being conducted using raw eggs with their shells being dipped in coke/juice, etc. and how by using particular toothpaste the stains on the egg shells can be removed with a tooth brush.

https://www.youtube.com/watch?v=pDVoIhSla0M
Students will come up with their responses after seeing the video as what is it all about and what have they learnt from what they saw in the video.


  1. Students were emailed a survey link for MS Excel Online as part of O365using MS Outlook.











Assessment For Learning: Summative assessment. (Attached)
The teacher will assess:


  • Are the children able to give reasons as to why we must care for our teeth using correct vocabulary?
