The space debate
I like that you use an approach the utilizes facilitation, guided practice, and independent practice. I would like to see an extension activity where the students would then become a senator and debate their point of view with the senate and a vote would be take for or against.
Really like the use of activities here for levelling assessments. It provides opportunities for literacy skills as well as problem solving etc. Really like the differentiation between the cards. Nice idea for a lesson! Thank you!
