As your child digs, fills and tips out the bucket they are exploring the space around them and the relationship between people and objects nearby. As they explore space they are developing mathematical ways of thinking. Mathematical thinking involves using memory, learning how to orient your body in space and making judgements about distance and size.
As the bucket fills up, your child will be hearing and using the different words and language we use to measure and describe size. This helps them to understand that we change words or language to describe an attribute of an object. The attribute could be time, temperature, size, space or capacity.
Digging, tipping and filling helps children to develop trunk and body control. Body control is needed to help develop good posture. If children do not have a good sitting posture they are not able to write for long periods of time because they will get tired and start to lean on the desk. Leaning over affects the range of movement children have for writing and drawing.
