'I Think ...' - Funday
Resource Asset
Resource Asset

This richly animated short features the unscripted voices of a group of 5- to 9-year-old children discussing concepts related to passing and measuring time, social routines, work, and leisure. (For notes on the significance of this resource go to 'metadata record' at the end of this description and see the 'educational value' section). While the discussion is centred on the idea of the weekend and is anchored in concrete examples and personal experiences, the clip demonstrates the rich, complex thinking and discussion possible among young children. Traditional animation and sound effects illustrate, reinforce and expand on the children's comments. [ Metadata record ]

'I Think ...' - The wheel turns
Resource Asset
Resource Asset

This richly animated short features the unscripted voices of a group of 5- to 9-year-old children discussing the concept of time. They consider time in terms of linear progression, cycles, and measuring time, and also discuss relationships between space and time. (For notes on the significance of this resource go to 'metadata record' at the end of this description and see the 'educational value' section). While discussion is anchored in everyday examples, the clip demonstrates the complex and abstract thinking and discussion possible among young children. Traditional animation and stop-motion using mixed media, along with sound effects, illustrate, reinforce and expand on the children's comments. [ Metadata record ]
