Calculate the duration of an event using appropriate units of time [M4]

The text provided appears to be an excerpt from a series of educational materials by Buzzard Publishing, specifically from their CanDoSATs KS2 range. These materials are designed to help Key Stage 2 students in the UK prepare for their SATs, which are standardized tests administered to children in Year 6. The focus of this particular excerpt seems to be on teaching students how to calculate the duration of events using appropriate units of time. The exercises likely include various problems where students must determine the start and end times of events, calculate the elapsed time, and express the duration using units such as seconds, minutes, hours, or a combination thereof.

The text includes a series of codes and symbols which might correspond to specific questions, activities, or instructions within the educational material. These could be references to worksheets, presentations, or interactive exercises that the students are meant to complete. The materials aim to develop the pupils' mathematical reasoning, fluency, and problem-solving skills, ensuring they are well-equipped for the demands of the SATs. The repeated mention of "Buzzard Publishing" and "CanDoSATs KS2" emphasises the proprietary nature of the content and its intended use within the context of UK primary education.
