24 weeks of review of 4th grade place value, addition/subtraction, rounding, and multiplication/division skills. Use as homework, a weekly in-class review, at a center, or with an intervention group. Each review clearly identifies which Common Core standards are covered. I chose Common Core standards that were skill based and have proven somewhat difficult for my students in the past. The sequence of standards reflects how many curriculums are structured, starting with place value and moving on to multiplication and division. There are seven different levels, with each level covering more standards as the school year progresses. Each level is also included as a template without specific problems so you can spend more time on some concepts if necessary before moving on to the next level. Additionally, the concepts students need to know to move on to the next level are identified clearly on the teacher outline. The reason I created these reviews is that I like students to have support and guidance when they are practicing so they can practice successfully. All of these reviews include helpful hints and strategies to promote student success. The reviews progress slowly so that even students that struggle can gain confidence. I use these reviews for assessment and progress monitoring as well. Although they do include hints and supports, I have found that they accurately reflect a student’s comfort with a skill. The hints and supports can also be covered up easily for assessments if you prefer. Please note, there is NO answer key. I am working on creating an answer key, but it will take a little while.
