Answers:

1- D
Even numbers always end with a digit of \(0, 2, 4, 6\) or \(8\).
So numbers \(30, 42, 18\) are just even numbers.

2- D
\(18 × 40 = 720\)

3- 42
3spaghetti with meatballs cost: \(3 × $10 = $30\)
2bowls of bean soup cost: \(2 × $6 = $12\)
3spaghetti with meatballs \(+\) 2bowls of bean soup cost: \($30 + $ 12 = $42\)

4- C
\(25 × 50 = 1250\)

5- 750
We round the number up to the nearest ten if the last digit in the number is 5, 6, 7, 8, or 9.
We round the number down to the nearest ten if the last digit in the number is 1, 2, 3, or 4.
If the last digit is 0, then we do not have to do any rounding, because it is already to the ten.
Therefore, the rounded number of 745 to the nearest ten is 750.

6- C
\(1\) hour \(= 60\) minutes
\(6\) hours\( = 6 × 60\) minutes\(⇒ 6\) hours\( = 360\) minutes

7- C
\(55 × 14 = 770\)

8- A
The model for the fraction is divided into 100 equal parts. We shade 88 parts of these 100 parts that it’s equal to \(\frac{88}{100}\)

9- B
\(12 × 8 = 96\)

10- C
Subtract 109 red cards and 88 white cards. The answer is 21

11- A
\(3 × 7 \space ⎕ \space 6 = 126\)
\(21\space ⎕\space 6= 126 ⇒ 126=21×6\)

12- B
Liam gave 455 of his marbles to his friend which means his marbles decreased then he lost 116 of his marbles which means his marbles decreased again.

13- D
\(33 + B + 8 = 66 ⇒ 41+B =66 ⇒ B =66 – 41 =25\)

14- C
If he eats 6 meals in 1 day
So in a week (7 days) he eats \((7 × 6 = 42)\) meals.

15- A
All these fractions; \(\frac{3}{9},\frac{5}{15},\frac{24}{72}\) after simplification are equivalent to \(\frac{1}{3}\).

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

17- C
Perimeter of square formula \(= 4 ×\) side \(⇒ 24 = 4 ×\) side \(⇒\) side \(= 6\)

18- B
3 rows that have 13 red cards in each row means: \(3 × 13 = 39\) red cards
And there are 24 white cards on the table too, so in total there are \(39 + 24 = 63\) cards on the table

19- A
Simplify \(\frac{4}{10}\) that’s equal to \(\frac{2}{5}\)

20- D
\(64 ÷ 8 = 8\)

Frequently Asked Questions

What is the SBAC math test?

The Smarter Balanced Assessment Consortium (SBAC) is a Common Core-aligned state assessment used by 12+ states. The grade 3 SBAC math covers the five Common Core grade 3 domains and four SBAC “claims.” Grade 3 is the youngest grade tested by SBAC.

What’s on the grade 3 SBAC math?

Five Common Core domains: Operations and Algebraic Thinking (multiplication, division, word problems), Number and Operations in Base Ten (place value, rounding), Number and Operations – Fractions (unit fractions, fraction equivalence on a number line), Measurement and Data (time, mass, volume, area, perimeter, bar graphs), and Geometry (categorizing shapes).

Is a calculator allowed on the grade 3 SBAC math?

No. The grade 3 SBAC math is fully calculator-free across all claims and the Performance Task. Students are expected to perform single-digit multiplication, basic division, and operations with whole numbers and fractions by hand.

Is the grade 3 SBAC math adaptive?

Yes. The Computer Adaptive Test (CAT) portion adjusts question difficulty based on your child’s previous answers. The Performance Task portion (a multi-step word problem) is not adaptive. Together they make up the full grade 3 math.

How long is the grade 3 SBAC math?

About 2.5 hours total, usually split across two or three sessions on different days. The CAT portion takes about 1.5 hours and the Performance Task adds another hour. Most schools let students finish on their own time within the testing day.

How is the SBAC scored?

Math gets a scaled score (roughly 2100-2700 for grade 3) and one of four achievement levels: Level 1 (not met), Level 2 (nearly met), Level 3 (met), Level 4 (exceeded). Most states target Level 3 or higher.

What’s the hardest grade 3 SBAC math topic?

Fractions on a number line (especially identifying equivalent fractions visually) and multi-step word problems are the two biggest challenges for most grade 3 students. Multiplication fluency within 100 also needs to be automatic — slow recall slows everything else.

Should my grade 3 child be timed during practice?

Not at first. Grade 3 is often a student’s first computer-based standardized test. Build accuracy and confidence first; introduce time pressure only in the last week of prep. The actual SBAC is largely untimed for grade 3 — accuracy matters more than speed.

How long should we prep for the grade 3 SBAC math?

For most grade 3 students, 4 to 6 weeks of consistent practice at 10 to 20 minutes per day is enough. Focus on multiplication facts, fraction concepts, and word-problem reading. Keep sessions short — third-graders fade fast on math homework.

Where can I find more grade 3 SBAC math practice?

EffortlessMath has the 3rd Grade SBAC Math for Beginners workbook covering every grade-3 SBAC topic and the 3rd Grade SBAC Math Test Prep Bundle with multiple full-length practice tests and answer explanations.
