Help your fourth grader walk into the California Smarter Balanced Grade 4 Mathematics test prepared, confident, and ready to do their best. This Smart Stars practice book contains five full-length practice tests modeled closely on the structure and content of the real CAASPP exam.
Every test in this book mirrors the operational format your student will face on test day: a computer-adaptive (CAT) section followed by a Performance Task built around a single rich, real-world scenario. Each practice test includes 36 questions — matching the combined operational plus field-test load students see online — across two untimed parts. No calculator. No reference sheet. Just the math your fourth grader has learned in class.
Take a look inside


After each test, your student gets the most valuable part: a complete answer key with detailed, plainspoken explanations. Every correct answer is walked through step by step, with a labeled Strategy and Tip that reinforce the underlying skill — not just the right answer.
What’s inside
- 5 full-length practice tests — 180 questions total
- 5 distinct Performance Tasks: Art Day, Garden Planting Layout, Field Day Relays, Class Pet Store, Farmers Market Stand
- Detailed answer explanations for every question, written for parents and students to read together
- A Letter to Parents and Students explaining what the test looks like and what is allowed
- 9 Test-Taking Tips written specifically for Grade 4 Math
- A Quick Answer Key in the back covering all 5 tests
- A clean, readable interior set in Times New Roman 11pt
About the field-test items: On the official Smarter Balanced test, about two CAT questions per student are unmarked field-test items the consortium uses to develop future tests. Students never know which items are scored and which are field test. We replicate that same total length in this book so your student builds realistic test-day endurance, not a falsely-short rehearsal.
