This packet includes 10 practice worksheets and 5 formative assessments for you to use with your students. These are aligned to the 3rd grade common core standards, 3.NF.1, 3.NF.2, AND 3.NF.3. These can be used with 3rd grade to practice written response questions, but more importantly, these can be used with your 4th graders who will be tested on the 3rd grade common core standards. With the new Smarter Balanced Assessment that will be given next year, it is important that we prepare our students for the written response questions that they will be asked to do. The stakes could not be higher for our students. Answer keys are included.
