Make the experiment adjustable
Agree on the goal, the time block and practical exceptions. Review what helped and what created work. Keep the useful part and change the rest rather than turning one difficult afternoon into a verdict on the whole family.
Before starting, check the materials and adult-help notes in the guide. Begin with a small version and keep a familiar alternative available. If the idea does not fit the day, simplify the task or choose a different pace; a longer list is not always the answer.
A useful next step
