Charlie, age 7, submitted these models.
Charlie’s models are very creative! His explains his model of “now”: “It is a model of me making the word now, which is what I was doing at the time.”
In his model of “while”, Charlie has used a thought bubble to show his model of self with a mental image of a bus. The arrow points to the main idea represented by the model — that “while” means “a period of time.”
