Answers:

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, 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 complete shaded triangles and a 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

How many questions are on the 3rd Grade GMAS Math test?

The Georgia Milestones End-of-Grade (EOG) Math test at grade 3 has about 50-55 items total, split across two sections. This free practice gives your child 20 sample questions that cover the same topics in a much shorter session.

Is a calculator allowed on the 3rd Grade GMAS Math?

No. Calculators are not allowed at grade 3. The test is designed to measure basic computational fluency — addition, subtraction, multiplication, and division — without any tools. Practice fact fluency at home throughout the year.

How is the 3rd Grade GMAS Math scored?

Each grade gets a scale score and a performance level: Beginning Learner, Developing Learner, Proficient Learner, or Distinguished Learner. Georgia targets Proficient or above as the grade-level expectation.

How long is the 3rd Grade GMAS Math test?

Each of the two sections has a 60-minute time limit. Most grade 3 students finish each section well within that. Total testing time is about 2 hours across two sittings, usually scheduled on separate days during the spring window.

What topics are on the 3rd Grade GMAS Math?

Operations and algebraic thinking (multiplication and division within 100, word problems, basic patterns), number and operations in base ten (place value, rounding, multi-digit addition and subtraction), fractions (understanding fractions as numbers, equivalent fractions), measurement and data (time, mass, volume, area, perimeter, bar graphs, line plots), and geometry (shapes, partitioning).

Can my child retake the 3rd Grade GMAS Math?

The Georgia Milestones EOG is given once per spring. There’s no individual retake within the year. If your child misses the original date due to absence, a state-approved make-up day is available within the testing window.

How long should we prepare for the 3rd Grade GMAS Math?

For most third graders, 4-6 weeks of light practice (15-20 minutes a day) is plenty. If multiplication facts aren’t solid yet, spend 2-3 weeks on fact fluency before tackling word problems. Take this practice test first to spot weak topics.

Is the 3rd Grade GMAS aligned to Common Core?

Georgia adopted Common Core in 2010, then revised and renamed the standards as the Georgia Standards of Excellence (GSE) in 2015. The grade 3 math content still aligns closely with CCSS 3.OA, 3.NBT, 3.NF, 3.MD, and 3.G.

What’s the hardest part of the 3rd Grade GMAS Math for most kids?

Two areas trip up most third graders: multi-step word problems (especially with multiplication or division) and fractions on a number line. Both reward slow, careful reading and drawing a picture or diagram. Practice these with your child throughout the year, not just before the test.

Where can I find more 3rd Grade Georgia Milestones practice?

EffortlessMath has lessons for every grade 3 GSE math standard, plus the grade 3 Georgia Milestones math workbook and additional full-length grade 3 practice tests.
