Lesson video

Hello everyone and welcome to maths with Mr. Revolski.

Today we'll be looking at measuring volume.

So let's have a look at today's lesson agenda.

First, we'll be launching a bit of an investigation, then you'll be measuring volume, finally, you'll be ready for your independent task.

So right now for this lesson, all you need is a pencil and a notebook.

If you don't have these items pause the video and go get them.

Super, so for today's lesson, you're going to need to be a bit of a detective and launch an investigation.

You're going to count and record the number of units you need to fill three different containers.

So I'll show you first using items and containers I found in my house, before you go off and launch your own investigation.

So have a look at what I do, and then we'll be ready for your independent task.

For this investigation it's really important that you ask an adult for help before you get started.

So what you'll need to do is find three different sized containers.

Here are mine, container A, container B, container C.

I will also need one smaller container that will act as my standard unit of measure.

Now that I have those items I need to make sure that I have my chart, container A, container B, container C.

I'm going to investigate.

How many units do I need to fill each of these containers? So let me show you an example.

I'm going to fill container A first.

One unit, I can still keep going.

Two units, still not full yet.

Three units, I can still keep going.

Four units, oh and now I filled it to the top.

So on my chart, I will fill in container A needs four units to fill it.

Every time I filled my unit I filled all the way to the top, to the brim.

If I don't do that each time, my results won't be very accurate, so it won't be a very fair investigation.

So no that I've done container A, I will do the same for containers B and C and make sure I put them on my chart.

So that is exactly what you will do for this investigation, good luck.

Super, so for your independent task, you need to answer the following questions.

So for example, what is the difference in volume of container A and B? Well, for me, container A held four units and container B held three units.

So I need to find the difference between three and four.

Oh that's right, three, four, so the difference is only one unit.

So that be my answer for the first question.

Because you have all used very different containers, the answers will be a little bit different.

So pause the video now, complete your independent task and then resume when you're ready, good luck.

Super, so as I mentioned before, you will all have had some very different answers for your independent task.

It would be really helpful if an adult at home could check your answers and make sure that you read the questions really carefully.

As always, if you'd like to, you can share your work with Oak National by asking your parent or carer to share your work on Instagram, Facebook, or Twitter, tagging @OakNational and #LearnwithOak.

It was really, really great to see all of you today, and I really hope to see you for future lessons, bye.
