Valoraciones y comentarios
Would this work a year group down with more scaffolding, or is the reading level too high?
Worked well as a cover lesson. A colleague with no background in the topic taught it from the plan alone.
Pairs nicely with the follow-up lesson in the same subject — I taught them back to back.
Really well structured. I adapted the warm-up slightly for my group and it worked beautifully. Saved me hours of prep.
