Notes et commentaires
The timing note says 50 minutes but it took us closer to 65. Worth budgeting the extra.
Students who normally disengage were arguing about the data by minute ten. I will take that.
That is a fair point about the sourcing — I have listed two substitutes in the materials now.
The differentiation notes are what sold me — I could stretch the fast finishers without writing anything extra.
A year down worked for me with the reading swapped for the summary version.
Setup was about ten minutes for me once the materials were out on the bench.
Sixty-five minutes matches my experience too. I now split it across two shorter periods.
Totally agree, the wrap-up is the strongest part.
