This product was designed for my third grade classroom. I use this product for RTI in my classroom. This product focuses on the skill of perimeter and correlates with the common core standard 3.MD.D.8 This product has 10 different forms that each contain 10 problems. The problems on each page test the skill of perimeter with unit squares, numbers, and finding the missing side length. This pack also includes a graph in which my students keep track of their progress on these quick assessments. The graph allows the students to see their progress and allows me to see if the student is mastering the skill over time. These probes also allow me to group my students into core, strategic and intensive groups based on their ability to complete perimeter probes.
