I’ve started giving students more IB exam problems so that they’ll be familiar with the problem format, wording, and content. I recently gave them a sequences and series one as a Do Now after they’d finished the unit. I told them to pretend as if it was a quiz so that they (and I) could see where they would stack up in a real IB problem situation. Similarly, I did not circulate to answer any questions (even clarifying ones), since I wanted to see if students would have any issues interpreting the directions.
My intern created a representative set of responses for us to bring to math team meeting, where I shared it with the 6th-11th grade math teachers. We are going to be sharing student work and IB rubrics over the coming year so that we are familiar with all levels of the curriculum. We all graded the student work and shared how we graded. We had a hard time deciding how tough to be as graders on some of them!
According to the markscheme, how would you grade the four students?
