FREE 4th Grade SBAC Math Practice Test

TL;DR: SBAC is computer-adaptive, used across California, Washington, Oregon, Hawaii, and a handful of other states. That means your 4th grader sees harder or easier questions based on how they answer. Try this free 20-question SBAC-style practice test as a calm preview. Work through the explanations together when your child finishes, and you’ll know which topics deserve more attention before the real adaptive test starts asking.

Key takeaways:

  • This practice set has 20 questions modeled on the real SBAC Grade 4 math test.
  • SBAC is computer-adaptive (CAT): question difficulty adjusts to your child’s answers.
  • Calculators are NOT allowed on the Grade 4 SBAC.
  • The real test has a CAT portion (~25 items) plus a Performance Task (1-2 extended problems).
  • 4 achievement levels: Below Standard, Near Standard, At Standard, Above Standard.

Answers:

1- C
\(6\) quarters \(= 6 × 25\) pennies \(=150\) pennies
\(9\) dimes \(= 9 ×10 \)pennies \(= 90\) pennies
In total Nicole has 251 pennies

2- A
\(1\) issue\(= $4\)
How many issue? \(= $72\)
\($72 ÷ $4= 18\) issue

3- C
Use perimeter of triangle formula.
\(P = a + b + c\)
\(P = 12 + 15 + 16 = 43\) inches

4- C
Use perimeter of rectangle formula.
\(P = 2(L + W)\)
\(60 = 2(10+W) ⇒ 2W = 40 ⇒ W = 20 \)feet

5- B
An obtuse triangle is one with one obtuse angle (greater than 90\(^\circ\)) and two acute angles. Since a triangle’s angles must sum to 180\(^\circ\), no triangle can have more than one obtuse angle.

6- C
\(1\) foot \(= 0.333 \)yard
So \(36\) foot \(= 12\) yards \((36 × 0.33)\)

7- B
The sum of \(A\) and \(B\) equals \(35: A + B = 35\), if \(A = 16\) we have \(16 +B = 35\)

8- D
\(A = 108 ÷ 9 = 12\)

9- B
Sum of these three angle are 180\(^\circ\).
\(A^\circ + 80^\circ + 16^\circ = 180^\circ\)
\(A^\circ =180^\circ – 96^\circ = 84^\circ\)

10- C
Use perimeter of trapezoid formula.
\(P = a + b + c + d\)
\(P = 2+ 6 + 2+ 8 =18\)

11- B
Low temperature is 24\(^\circ\)f cooler than the temperature at 12:00 PM that is 76of, that means low temperature is 52\(^\circ\)f (76\(^\circ\)f \(-\) 24\(^\circ\)f) that is close to choice B

12- A
\((4 × 10) + (7 × 1) + (6 × 0.01) = 40 + 7 + 0.06 = 47.06\)

13- D
1 year \(=\) 365 days, 1 day \(=\) 24 hours
1 year \(=\) 365 × 24
1 year \(=\) 8,760

14- B
Each game = \(\frac{11}{2}\) hours = 90 minutes so 3 games = \(\frac{41}{2}\) hours = 270 minutes
5minutes between each game, so there is 10 minutes in total between 3 games.
She arrives 15 minutes before first game and left 10 minutes after the last game.
In total she was \(270+10+15+10 =305\) minutes at the soccer field.

15- A
You can find if a shape has a Line of Symmetry by folding it. When the folded part sits perfectly on top (all edges matching), then the fold line is a Line of Symmetry. Here the first shape shows a line of symmetry.

16- B
Find the least common denominator (LCD), then rewriting each term as an equivalent fraction with the LCD. Then we compare the numerators of each fraction and put them in correct order from least to greatest or greatest to least.
LCD of 2, 8, 4 and 16 is 16. Rewrite the input fractions as equivalent fractions using the LCD:
A. \(\frac{8}{16}\)
B. \(\frac{6}{16}\)
C. \(\frac{12}{16}\)
D. \(\frac{9}{16}\)
So choice B has the least value.

17- D
12 pastilles\(=\) 1 box
336 pastilles\(=\) (\(336 ÷12 = 28\)) boxes

18- 64

Use volume of cube formula:
V\(=a^3\)
V\(=4^3 =64\)

19- C
Arrow shows exactly the middle of two numbers 25 and 35, so the answer is 30

20- A
This shape shows 3 complete shaded triangles and a half of a triangle that is equal to \(3\frac{1}{2}\)

Frequently Asked Questions

How many questions are on the 4th Grade SBAC math test?

The full SBAC Grade 4 math test has two parts: a computer-adaptive section of about 25 questions and a Performance Task of 1-2 extended multi-part problems. Total testing time is around 2 hours, usually split across two days. Our free practice gives you 20 questions covering the highest-frequency topics.

Is a calculator allowed on the 4th Grade SBAC?

No. Calculators are not allowed on the Grade 4 SBAC math test. SBAC enables an on-screen calculator starting in grade 6 on certain sections. Your fourth grader should be comfortable with multi-digit arithmetic and fraction operations by hand.

What’s a passing score on the 4th Grade SBAC?

SBAC reports 4 achievement levels: Level 1 (Below Standard), Level 2 (Near Standard), Level 3 (At Standard, aka “Met”), and Level 4 (Above Standard, aka “Exceeded”). Level 3 is the on-grade target, and the Grade 4 math scale score cutoff for Level 3 is 2485.

When is the SBAC given?

SBAC is given each spring, typically in March through May. Each state and district sets the exact window within the SBAC consortium calendar. Ask the school for the specific testing days at your child’s building.

How is the SBAC scored?

SBAC math scores combine the CAT portion and the Performance Task into a single scale score (roughly 2280-2700 at grade 4) with one of 4 achievement levels. The CAT items auto-score; the Performance Task is hand-scored by trained readers. Reports usually arrive 4-8 weeks after testing.

Can my child retake the SBAC?

The summative SBAC is given once per year, with no in-year retake. If the score comes back below “At Standard,” the school may add extra math support during the next year, and your child takes a fresh test the following spring.

What math topics are on the 4th Grade SBAC?

SBAC tests Common Core Grade 4 standards across 4 claims: Concepts & Procedures (the bulk of the test – multi-digit operations, fractions, decimals), Problem Solving, Communicating Reasoning, and Modeling & Data Analysis. Specific topics include place value, multi-digit multiplication and division, fractions, area and perimeter, and angle measurement.

How long should we study for the 4th Grade SBAC?

About 6-8 weeks of light practice (15-20 minutes a day, 4 days a week) is the sweet spot. Start with a diagnostic, drill the weak topics first, then move to full timed practice in the final 2 weeks. The Performance Task takes some getting used to, so try at least one before test day.

Where can I find more 4th Grade SBAC practice?

EffortlessMath has free lessons for every Grade 4 Common Core math topic SBAC tests, plus the Common Core Mathematics Workbook for Grade 4 and a practice test bundle. The lessons below this practice cover the highest-impact topics for SBAC.

Is the SBAC aligned with Common Core?

Yes – SBAC was built explicitly to assess Common Core State Standards. The 4 claims map directly to Common Core math practices. Any Common Core Grade 4 math materials work well as SBAC prep.
