Whether it is bath water or a jar of sweets, the terms empty and full are very important when talking about capacity. This is an area of maths which is quite interesting with young children. They will decide which container holds the most by its height rather than size and it is well worth spending some time filling different containers with the same amount of water. Try filling a tall glass with three cups of water and a short, fat glass with four cups of water so that the tall glass has a higher level of water. Even though a child knows that there are only 3 cups of water in the tall glass and 4 in the  short glass, they will still say that there is more in the tall glass. Fascinating! This is the latest in our great range of fun  maths activities which will quickly help your child become confident with number and enjoy their maths.
