Use E after Days 21–24 and F after Days 26–29. Give only the first source and task. Allow about 20 minutes, then keep the response. The teacher gives the matching later condition for about 10 minutes of review. Working may be on another sheet.
Paper and pencil are enough. Blank diagrams, a table, a calculator or a scribe may support an agreed access plan; record the help. The learner chooses the quantities, operations and decision. A previously seen source or answer cannot supply fresh evidence. These forms are formative and are not statistically equated or a whole-year grade.
