Give your fourth grader the confidence to succeed on the Alaska AK STAR Grade 4 Math test.
This Smart Stars practice book provides five full-length, standards-aligned practice tests that mirror the length, item mix, and question types of the real AK STAR spring assessment in Mathematics. Every question was written by experienced educators, reviewed for accuracy, and built around the Alaska Mathematics Standards at Grade 4 (Alaska’s own standards, not the Common Core) so the topics and emphasis match what Alaska students actually see.
AK STAR (the Alaska System of Academic Readiness) is the test the Alaska Department of Education & Early Development gives to every public-school student in Grades 3:9. On the test a student answers about 31 scored questions: 29 quick-answer plus 2 written-response: with a few unscored field-test questions mixed in invisibly. Each practice test here follows that same shape: 31 scored-style questions plus 5 field-test-style questions, 36 in all, for 180 questions across the book: to build true test-day endurance.
What’s inside
- Five full-length practice tests, with detailed Answers and Explanations after every test
- Field-test-style questions blended invisibly into each test, just like the real AK STAR, and fully answered here so nothing on test day feels unfamiliar
- Every explanation walks through the reasoning step by step and ends with a labeled Tip, Check, or Estimate (with a Strategy on the multi-step questions), so students learn the move, not just the answer
- A combined Quick Answer Key after each test for fast self-grading
Topics covered
- Place value to 1,000,000: reading, writing, comparing, and rounding multi-digit whole numbers, standard and expanded form, and how a digit is worth ten times the place to its right
- Adding and subtracting multi-digit whole numbers with regrouping, and multi-digit multiplication (up to 4-digit by 1-digit and two 2-digit numbers, with area models) and division with remainders
- Factors, multiples, and prime and composite numbers; “times as many” multiplicative comparison; multi-step word problems that use a letter for the unknown and interpret remainders; and generating and analyzing number patterns
- Fractions as numbers: equivalent fractions, comparing and ordering fractions, adding and subtracting fractions and mixed numbers with like denominators, decomposing fractions, and multiplying a fraction by a whole number (denominators 2, 3, 4, 5, 6, 8, 10, 12, and 100)
- Decimal notation for fractions, and comparing decimals to hundredths
- Area and perimeter of rectangles, including finding an unknown side and composite figures
- Measurement conversions for length, mass, and time, and combining measurements
- Measuring and identifying angles with a protractor, and finding an unknown angle from its parts
- Line plots marked in halves, quarters, and eighths of a unit
- Points, lines, rays, and parallel and perpendicular lines; classifying triangles and quadrilaterals; and lines of symmetry
- Analyzing data and explaining reasoning in two-part and written-response tasks
Why parents and teachers choose Smart Stars
- Educator-authored. Every question is written and reviewed by classroom-experienced educators.
- Mirrors test day. Each practice test matches the official AK STAR shape, item mix, question formats, and no-calculator, no-reference-sheet policy, with field-test questions blended in invisibly just like the real test.
- Explanations teach the why. Every Answers and Explanations entry shows the full worked solution, then a labeled closing Tip, Check, or Estimate (and a Strategy on multi-step problems) so students learn the reasoning.
