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.
