Teacher feedback:

  • This resource is perfect for teaching students how to write scientific arguments with evidence. It pairs nicely with my adopted science curriculum.
  • My students used this as individual anchor to refer to when using the CER writing in Science. My students and I found this resource helpful especially for students who are new to this strategy. Several of them kept referring back to chart to check their responses.
  • Of all the CER products I looked at, this one seemed to be the most thorough.
  • There were some helpful tips on how to start teaching CER. I liked the suggested videos to help students get better at applying CER to daily situations.
  • I love that this resource provides multiple ways to use the material, and it is very clear! It lines up perfectly with what I'm currently teaching and there is a rubric!!

This resource will help your NGSS aligned units.
