'Bottles (2)' printed from http://nrich.maths.org/
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:
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.
