EM2 assessments are designed to diagnose whether students have specific misunderstandings or misconceptions about rational numbers, such as fractions and decimals. All EM2 assessments require that students provide both a multiple-choice response and a written explanation for their answer. Students’ selected responses diagnose whether they are likely to have a targeted misconception, while their written responses are available so teachers can confirm how students are thinking about the problems. In this way, teachers have solid information about why students are having difficulty.
