Reflection: Rigor Save the Gingerbread! - An Assessment Task on Density - Section 2: Construction


This lesson had a challenging performance task.  This task might be tough for middle schoolers and high schoolers to complete, so how could I possibly expect kindergarteners to complete it? First off, this isn't the beginning of the school year.  Secondly, the students have been engaged in challenging tasks all year.  I have set the bar high for my students and they have reached for it.  They have shown a level of thinking that many older students do not possess.  They have showed they can work as a team and that they can effectively communicate their ideas.

This would not be something you would jump into without some scaffolding.  The students need modeling. I am constantly "thinking aloud" for my students.  I model for them how problems can be identified and addressed.  I model for them how we often must try things multiple times before we are successful.  Students can't be given worksheet after worksheet and then be expected to be successful with this kind of task.  It won't happen. 

I am excited about the future of my science instruction.  I have gained so much this year, I can't wait to learn more and to challenge my students with tasks like this one.  I want to continue to find ways to scaffold these tasks so future students can be even more successful.  They have so much potential, it is a joy to be able to unlock it.

Save the Gingerbread! - An Assessment Task on Density

Unit 6: Sink or Swim
Lesson 10 of 11

Objective: Students will be able to demonstrate their knowledge of density by constructing a model.

Big Idea: Could a well constructed raft save the gingerbread boy from being eaten by a fox? This performance assessment gives students the opportunity to find out!
