Bottles (2)
In this activity focusing on capacity, you will need a collection of different jars and bottles.
Age
5 to 7
Challenge level
This activity follows on from Bottles (1) which you may need to look at first.
You need to find a collection of jars and bottles of different sizes and shapes, like those in the picture below:
Image
You could use this picture as an example and number the bottles/jars 1 to 8 from left to right.
So, your challenges would be:
How many 2s are needed to fill 1?
How many 3s are needed to fill 4?
How many 2s are needed to fill 6?
How do you know?
You could create your own questions for yourself or friends to answer.

Why do this problem?
This problem is useful for pupils to consolidate ideas associated with capacity and to begin to calculate in that context. It allows for good discussion between pupils and between pupil and teacher.Possible approach
You could initiate some discussion by looking at the bottles pictured here, however having a set of your own bottles/jars would be better.
Give the pupils a long time to both discuss their answers and how they might validate them. Then give them chance to carry out some practical tests to see how close they were.
The activity Bottles (1) would be good to try before this. Some pupils made need assistance with any awkward pouring.
