The grade level that is targeted by each set of practice tests appears to the right of the set. Each test in the set has an answer key. Solutions for the problems in each set are not provided. The higher the test numbers in a set indicates a more current set. For example: Number Sense tests 311 – 320 is a more current test packet than Number Sense tests 301 – 310. Tests can be used for individuals to practice their knowledge of the content areas (Number Sense, Calculator Applications and Mathematics).
