Ran it twice this term with very different groups and it held up both times. That is rare.
Noted, I will add a timing warning to the description.
Please do share the translation, that would help a lot of us.
My students loved the hands-on part. The exit ticket gave me exactly the formative data I needed. Highly recommend.
A year down worked for me with the reading swapped for the summary version.
Good to know the hook travels — I will try that.
The assessment rubric alone was worth it. I have reused it across three other lessons since.
Glad it was useful. Let me know how the series goes.
Thanks, this is really helpful feedback.
Sixty-five minutes matches my experience too. I now split it across two shorter periods.
