Teaching teeth in year 4

Are you looking for planning resources for teaching teeth in year 4? Here’s how you can use our new downloadable teeth teaching resources to easily create memorable lessons that produce the sticky knowledge that Ofsted will be looking for…

Where to start?

Teeth should be taught before the digestive system. By year 4, most children will have lost several of their baby teeth and will be at the in-between stage with a mixture of adult teeth, baby teeth and some gaps. It’s fun to get pupils to look in a mirror and examine their own mouths! Children will already know that they have two sets of teeth. What they probably don’t know is that their adult teeth started growing while they were still a baby! They probably also don’t know how many teeth they have, what they are called and what they are used for. Our Model Mouth Lesson Pack answers all of these questions. It has been written by an experienced primary school teacher and is ideal for teaching teeth to year 4 pupils. The downloadable pack includes:

  • A teeth lesson plan
  • A PowerPoint presentation
  • Instructions for making a model mouth
  • A printable Wibble Wobble tooth game
Model Mouth lesson pack

Why build a 3D model mouth rather than asking children to label
a worksheet?

All pupils learn differently, and to create sticky knowledge children need memorable experiences. The visual and kinaesthetic learners are more likely to remember making a 3D model mouth than filling in a worksheet. They will physically make 32 teeth and mould each tooth into the correct shape. Once the models are complete, you can discuss how we keep teeth healthy. Pupils could even practise brushing their model teeth

How to evidence the lesson

If your planning isn’t enough evidence, pupils could use the Keynote app on an iPad to record themselves describing their model mouth and each tooth’s name and function. If you need evidence in their books, you could print a photo of the model and during morning work the next day, pupils could label and annotate it. This would mean that they go back over their learning from the day before, helping the knowledge to stick. Our Wibble Wobble board game is also a good way for children to revisit the subject. Knowledge organisers can be an additional tool to help remind children of previous learning, or to use as a scaffold – not for answers!

What to cover next

Pupils should then research other animals, both herbivores and carnivores, that have teeth. What similarities and differences do they notice? Do all the animals have the same number of teeth? Do they all have molars, canines and incisors? Are they called something different? Why don’t some animals have teeth? Once children start researching, they will hopefully come up with lots of questions they would like to find out the answers to. Our downloadable Animal Antics text on vipers is a good place to start.

Further investigations

We also have another year 4 downloadable lesson plan on teeth, which is an observation over time enquiry. Pupils will set up an investigation to observe eggshells in different liquids. Eggshells and teeth are both made of calcium-based compounds so this is a good visual demonstration of how some drinks can cause damage to our teeth. Our lesson plans always explain the science behind the lessons – teachers can’t remember everything!

How to make teeth cross-curricular

Making the model mouth links to art and sculpture. There are also lots of ways to embed the pupil’s science learning in your school day. Using science texts in guided reading or whole class reading sessions is an easy way for children to delve further into the subject matter and acquire more knowledge. We have three reading comprehension packs for year 4:

We also have a bank of spectacular science images that are perfect for promoting discussion. They feature a striking scientific image, along with a couple of questions. As you click through the PowerPoint presentation, the answers to the questions will be revealed. Pupils should try to answer the questions as you go. The presentation to use for teeth is called ‘Smile crocodile’. It only takes ten minutes so it can slot into those awkward times in the school day – for example, straight after lunch while you are waiting for everyone to come in.

Fossilised animal poos are known as coprolites. They are full of clues about what dinosaurs and other prehistoric creatures liked to eat. The largest coprolite ever found was a Tyrannosaurus rex poo. It is full of crunched-up bones.

The largest collection of coprolites is owned by George Frandsen in the USA. In 2017, he had 1,277 fossilised dino poos, including the largest ever found! See him showing off the record-breaking dino poo here:

The secrets of stinging nettles: natural navigation with Tristan Gooley

The August edition of Whizz Pop Bang: ON THE MOVE is about amazing migrations and is packed with the science behind all sorts of incredible journeys made by animals and humans!

Inside, we chat to Tristan Gooley, a natural navigator who looks for nature’s clues and works out how they can help us to find our way. Learning more about this fascinating skill is a brilliant way to engage children with the natural word – keep reading to learn a nifty tricky you can teach them when you’re outdoors together.

We asked Tristan to explain a little about his unusual job:

“Every single plant, every single animal, even every single cloud is telling us something about what’s going on around us. I’m a nature detective, trying to solve each clue. I don’t look for specific things that are interesting or amazing: instead, I wonder what the signs around me can reveal. Sometimes it’s a plant showing me which way is north, or a stinging nettle telling me I’m near a town. It’s so much fun!”
Tristan Gooley in Whizz Pop Bang: ON THE MOVE

Tristan Gooley, Natural Navigator

If you’re wondering how to keep children entertained on a long walk or how to help your child connect with nature, here’s a tip from Tristan all about the secrets of stinging nettles:

If you teach children a trick that is related to their experience of the wild then you could grab their attention

Find an area with both stinging nettles and white dead-nettles:

White dead-nettle
Stinging nettle

Ask the children what the white dead-nettle is – they will probably guess ‘stinging nettle’. Most kids can identify this before any other wildflower, because it has a big impact on their experience of the outdoors!

Next, show how brave you are by running your hands up and down the white dead-nettle, then dare them to do the same. Once they realise that white dead-nettles are different to stinging nettles, they take an interest. They understand that the white flower is the important clue to which one stings, and that’s something worth remembering!

It also tends to stick as this is a great trick for showing it off to other kids!

Nature appreciation that leads to fewer stings AND the ability to show off? That’s a recipe for getting kids interested!

Find out more in this brilliant blog post about engaging children with nature. Want more tips like this? Head over to Tristan’s website to discover all sorts of intriguing ways to read nature’s clues – they’re guaranteed to liven up a long walk with children!
