The document discusses assessment activity K which involves matching words to definitions on a worksheet. It provides the steps of the instructions in logical order: 1) the teacher holds up the worksheet, 2) points to the left side, 3) introduces the task of matching words to definitions, 4) points to where the definitions are, 5) notes there is one extra definition, 6) specifies doing it alone and checking in pairs. It then asks questions about the sequence: which steps give instructions and which check understanding, and why the teacher waits to hand out the worksheet. Finally, it discusses when the best time would be to give an instruction to change seats.
