This week, we'll be looking at capacity - this is how much a container is able to hold e.g. the capacity of a glass is how much liquid it can hold when full. To start with, the children will be practically exploring this using water, sand or mud (or anything you are able to use at home) before moving on to learning about litres. Before you start each day, please practise your 2s, 5s or 10s and complete the 5 a day activity. The videos are hosted on YouTube so there may be adverts.
Today will be mostly be a practical activity - after watching the video below, have a go at answering the questions by solving them practically with containers and water/sand/anything else you are able to use. There is a brief worksheet that will need to be completed as part of this. Once you have finished the task, there are some further questions to think about as an extension - you may wish to prove these practically as well.
Can you set up two containers the same size (or roughly, if not possible) - one empty and one full?
Can you set up three more - nearly empty, nearly full and half full? Fill in the worksheet to show the containers you've set up!
What would happen if you had two containers that were half full and you poured them into the same container? Can you prove it?
Do all your containers have the same capacity - are they able to hold the same amount when full? Can you prove it?
As a starter, have a go at the following questions:
Does the taller container always have a bigger capacity? Can you prove it? You could use smaller containers, such as spoons or cups, to work it out e.g. Container 1 has a capacity of 5 cups of water (it can hold the same as 5 cups), Container 2 has a capacity of 3 cups of water (it can hold 3 cups). Have a go, using cups or spoons (or other small containers) to help you!
Once you've had a go at this, look at the presentation with the example questions. As an extension, there are some problem solving questions - don't worry if you can't get on to these, just stop the presentation when it gets to that point.
Today we're introducing the idea of litres and using them as a way of comparing capacities, as well as helping the children gain an understanding of how much a litre is. After watching the video, please have a go at filling in the worksheet through using practical means - liquid, sand, mud or anything else you are able to use is fine.
The first part of the activity looks at investigating whether containers have a capacity of at least a litre or not (are they able to hold a litre). The second part of the worksheet asks you to find out how many glasses/bowls/spoons you can fill using a litre - you can just choose one of these to investigate if you would prefer. If you are unable to measure litres exactly when working on the problems then estimating is OK as it's more important that the children get used to the terminology.
As a starter today, please have a go at Addition and Subtraction games on Hit the Button (found in the Number Bonds section).
Have a go at the arithmetic test below - remember, try to focus on your speed and accuracy. Once you've finished it, try one of the games.
