Lesson video

Hello everyone and welcome to maths with Ms. Dobrowolski.

In this lesson we'll be looking at using length, weight and volume.

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

First up, we have a Applying Measure.

Then you'll have your Talk Task, followed by Measuring Mass and Capacity.

And then finally you'll be off for your Independent Task.

So for this lesson, you will need a pencil and notebook if you don't have these items, pause the video now and go get them, super.

So when do you measure things in real life? Have a think, hmm, I measure things in real life.

When I'm cooking for example, I need to measure exactly how much flour I need for my cake.

Exactly how much salt I need to put on my chicken and other things.

When is it important to use measure and why? Hmm, well in my cooking, it's really important to use measure because I don't want to make, you know, my cake too sweet, or my chicken too salty.

Or I don't want my cake to fall flat if I don't put enough bicarbonate in it.

So it's really important to measure so that we're specific and we do things the way we're supposed to.

And have you ever seen people measuring have to think about maybe on your walk to school? Or when you're outside at the park? What have you seen people measuring? Hmm, I know I've seen people measuring at the shoe store.

When people need to get new shoes.

Sometimes a person will come and measure their feet to see how long their foot is so they get the right shoe size.

Now, let's have a look.

I have some characters here.

Which character is the shortest? Pause the video and try and figure that out resume when you have an answer.

So which character is the shortest? I can see that the ginger breadman is only three units tall.

One, two, three.

Grandma is one, two, three, four units tall and grandpa is one, two, three, four, five units tall.

So that must mean that the gingerbread man is the shortest because he's only three units tall.

Three is less than four and five.

What about tallest? Which character is the tallest? Hmm, if you've guessed Grandpa, you're correct.

That's because grandpa is five units tall one, two, three, four, five.

So grandpa is the tallest.

Who is shorter than grandma? Well, let's take a look.

Grandma is one, two, three, four, units tall.

Hmm.

Is there anyone on this screen that's less than four units tall? That's right.

The gingerbread man is only three unit tall.

So I know that the gingerbread man is shorter than grandma.

Can you find anything in your home that is taller than a metre? And if you think it's taller than a metre, how could you check? Pause the video now see if there's anything that you can find that's taller than a metre, it is very likely that anything taller than you will be taller than a metre.

If you don't have a metre stick at home, measure it.

So for example, I know that I'm taller than a metre.

So I guess since I'm in my home, I found an object already.

It's me.

Super.

So let's have a look at mass.

What has a greater mass, the orange or the banana? Now remember, this is a scale.

So I can see that the orange has a greater mass because it weighs more on the scale, right? It's tipping lower than the banana so it must be heavier than the banana.

Your turn.

If a marble is a unit, how many units does the present way? Here are the marbles? And if a marble is equal to one unit, how many units does the present weigh? Pause the video and try and figure it out resume when you have an answer.

Super.

So hopefully you got an answer of six units because I have one, two, three, four, five, six marbles.

And if one marble is equal to one unit, then six marbles is equal to six units.

And I can tell from the scale that the present and the marble have this weigh exactly the same, because they're even on the scale.

Let's try another one.

What can you say about the mass of flour? Pause the video and have a think resume when you're ready.

So What can you say about the mass the flour? What do you think? Well, I can see that this is one kilogramme, and it is equal to the flour.

That must mean the mass of the flour is equal to one kilogramme.

Super job, everyone.

Now, let's try our talk task.

I have a gingerbread man and the star here.

I want you to tell me how long each of these shapes are and which one is shorter and which one is longer.

Make sure you're using this mathematical language.

The gingerbread man is one, two, three, four, five, six units long.

Your turn pause the video complete your talk task and resume when you're ready.

Super, so I can see that the gingerbread man is six units long.

The star is one, two, three, four, units long.

That must mean the gingerbread man is longer than the star, and the star is shorter than the gingerbread man.

Now, this is a weighing scale.

What do we use weighing scales for? Where have you seen this? I've seen these in my kitchen.

I've used them to weigh, for example, ingredients in my recipe.

You may also have seen them at the supermarket because sometimes we use weighing scales to weigh our fruits and vegetables, and even meat sometimes.

You've probably seen them at the supermarket or maybe even at home.

Now, as you can see, on my weighing scale, this weighing scale goes all the way up to 10 kilogrammes.

So I can weigh something on here, but it only can be up to 10 kilogrammes.

Anything past that would be too heavy for my weighing scale.

I need a bigger weighing scale.

So Which spoon has the greater capacity? The tablespoon or the teaspoon? What do you think? That's right, the tablespoon has a greater capacity, the teaspoon is very, very small compared to the tablespoon, the tablespoon can actually hold more than a teaspoon.

Now, this independent task is a little bit different.

Because for this independent task, I'd like for you to try making just some gingerbread.

I've given you the recipe.

So as you can see, you have the ingredients on one side of the screen and the instructions on the other side of the screen.

Now, if you are going to complete this independent task, you must must ask an adult for help because you will have to get a lot of ingredients from the kitchen and you will have to be turned and you will have to turn on the oven.

So if you would like to take part in this independent task, you must ask an adult for help.

So feel free to pause the video asked an adult for help and complete the independent task where you get to measure some ingredients out.

Super job everyone that was really good work.

Even if you don't get to complete the independent task today, perhaps you can do it at some point in the future.

If you'd like to as always, you can ask your parents or carer to share your work with OakNational by sharing your work on Instagram, Facebook or Twitter tagging @OakNational and #LearnWithOak.

As always, don't forget to complete your final quiz and I really hope to see you again for future lessons.

Bye.
