Data is the information children collect by observing, asking questions or testing out ideas. When children describe what they see in groups of objects they are making sense of the information and can, with support explore how they can represent the information. These learning possibilities present a number of playful experiences that invite children to explore the grouping of objects by characteristic, number or preference and the relationships that can be described as a result of the information gathered. A children's story is also provided that includes specific language or ideas that support children's growing understandings of data.
