Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.
These resources were created for remote use during the pandemic and are not designed for classroom teaching.
Lesson details
Key learning points
- Teeth are part of the human digestive system.
- Different types of teeth have different functions, but work together to break down food to travel through the body.
- Incisors are sharp and flat, and are used to cut and bite food.
- Canines are sharp and more pointed, and are used to rip and tear food.
- Molars are wide and bumpy, and are used to chew and grind food.
Keywords
Digestive system - The digestive system breaks down food into small particles, which are absorbed into the blood.
Functions - The tasks or jobs that a thing has are its functions.
Incisors - Incisors are teeth that are used to bite and cut food.
Canines - Canines are teeth that are used for tearing and ripping food.
Molars - Molars are teeth found at the back of the jaw with a rounded or flattened surface. They are used for grinding and chewing food.
Common misconception
Children may think that all teeth are the same and that they perform the same job to break down food in exactly the same way.
Eating a few different types of food (Task A) will help children to see for themselves which teeth they are using and what they are actually doing to break down food in different ways.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
