# Lesson observation on using and applying maths on rivers

Hi,
I have a 30 minute lesson observation next week which requires me to teach a lesson which 'demonstrates using and applying maths through next term?s topic on rivers'. Does anyone have any good exciting ideas i could use? I thought about doing something about how many River Thames can fit into the River Nile or something like that but since it is an observation i do not want it to be boring. Help?!

Using maths with rivers requires a river!! You can measure flow and depth. Tricky in the classroom though but a good field trip (if you can do the paperwork).

Exactly but since this is a lesson observation for an interview slightly impossible!

You could link it to water use - a vague link but people do use water from rivers. Sounds like a demanding observation. Good luck

How about the volume of water dumped into the sea by your local river. How much per day/month/year? This is hard.

speed of water flowing? graph it or the depths of water at different points? use a known river but be creative with the depths etc or the width. Could you link it to a journey along the river - things you see? What year group?

Could you create a 'temporary' river in the playground using a bucket and downhill slope perhaps? You could then observe the processes of transportation & deposition of particles. Not instantly sure how you'd link it to Maths but it would be v. hands on & practical. Alternatively, you could get the chn in a circle to pass round & shake large pieces of chalk in a container to mimick the action of the river on pebbles. They could observe, estimate and measure the larger pieces of chalk at the end to see the impact on mass perhaps. Thinkng about it, you could then put the chalk dust into your temporary river and observe while it was being carried away...

These convoluted links get on my nerves.
I like doing topics but if the maths doesn't fit easily and obviously ... why link it?
Sorry, that's not much help to you - what year group?

Thanks everyone some ideas here!! They will be year 5 its going to be hard to plan something for this with a tedious link to rivers! I am a maths specialist and finding it hard as an NQT to think of a good lesson

How about researching the length of some rivers, scaling down the measurements to manageable numbers and measuring out lengths of string for each river, to scale?

That seems like a great idea, might steal that for the future!! I have decided to go down the word problem route linking in the usage of water in the school. For example, IIf a sink uses 2 litres of water every time it is used and it is used 20 times a day how much water does it use? If this is for one sink how much water is used if there are 7 sinks?
Then the children can go onto to find out how much would be used in a week and compare this to the average usage. Not too creative but its the best i can do for a lesson observation without going too wild!

I'll think I'll take 5% of future wages as commission
Seriously - I have just had a water meter fitted and it is fascinating looking at how much water is used for baths, showers and toilets. A bath is 80 litres and a toilet is 5 - 6 litres (unless you have a Hippo) A shower is maybe 20 - 30 L (time dependant) - good maths there.

Haha thank you!
I thought if i made it interesting like you say they might be more interested...
