How to use it in your classroom
A simple test prep plan for the CMAS test:
- Start with the Pretest. It is half the length of a practice test, and its scoring guide shows which standards each student needs most.
- Teach and practice by standard. Each skill has a Learn It page with a worked example, then test-style practice in the same question formats as the CMAS — great for small groups, centers or homework.
- Keep skills fresh with Mixed Review. Short cumulative pages mix every reporting category, so earlier skills don’t fade.
- Give the practice tests before the big day. Practice Test 1 shows what to reteach; Practice Test 2 is a full dress rehearsal for the spring state test. Bubble answer sheets and the class data sheets make scoring quick.
Free with a membership: a Have Fun Teaching membership includes the Printable PDF of every test prep workbook. The paperback is sold on Amazon and is not included.
