A B Pot B holds 11 glassfuls of water. Pot A holds twice as much water as pot B. How many glasses of water are needed to fill pot A?

They must get many opportunities to use words like 'glassful', 'bucketful' etc. They will also get familiar with ideas such as 'half', 'twice', 'four times' the amount of water, and a sense of roughly how much one litre is. 158 Filling Potholes This is a small town near Kohima.
