Top 10 3rd Grade Georgia Milestones Assessment System Math Practice Questions
TL;DR: Third grade is the first big year for Georgia Milestones, and the math test can feel like a lot to your child. These 10 practice questions are the perfect warm-up: real GMAS-style problems with clear answers, designed so the two of you can sit down and talk through the reasoning together. Use them as a low-pressure first look at the format so test day feels familiar rather than brand new.
Key takeaways:
- Georgia Milestones (GMAS) Math at grade 3 tests every K-12 math domain at the third-grade level.
- The test is computer-based with roughly 50-60 items split across two sessions on separate days.
- Major content areas: multiplication and division within 100, fractions, area, and measurement.
- No calculator at grade 3 – solid recall of multiplication facts up to \(10 \times 10\) is essential.
- “Proficient Learner” is the on-grade-level mark, typically around 525 on the scale score.

Answers:
1- B
An easy way to tell whether a large number is odd or even is to look at its final digit. If the number ends with an odd digit \((1, 3, 5, 7, or 9)\), then it’s odd. On the other hand, if the number ends with an even digit or \(0 (0, 2, 4, 6 or 8)\), then it is even.
15, 29, and 83 ends with an odd digits, so they are odd numbers.
2- D
She saves $36 and $28 so she has $64.
\($140 – $64 = $76\) she needs to save.
3- D
Michelle divides 72 books into 9 boxes therefore \(72 ÷ 9\) formula is correct.
4- B
Eva gave 349 of her 983 cards to her friend so her cards are \(983-349\), then she lost 260 cards so now she has \(983-349-260=374\) cards
5- D
Use are formula of rectangle:
\(Area= length × width\)
Area \(=3cm×7cm =21cm^2\)
6- B
Add 4hundred and 8 tens and 4ones
So we have :\(400 + 80 + 4 = 484\)
7- A
The chances of landing on red are 3 in 6
The chances of landing on yellow are 1 in 6
The chances of landing on green are 2 in 6
The chances of landing on red are more than other colors.
8- C
32inches distance most occur in this table.
9- A
10- C
All these equations are true:
\(98 – 31 = Z\)
\(98 – Z = 31\)
\(Z + 31 = 98\)

Frequently Asked Questions
What’s on the 3 grade Georgia Milestones Math test?
The Georgia Milestones (GMAS) Math test at grade 3 covers multiplication and division within 100, fractions (including on a number line), place value, area, time and measurement, and reasoning with shapes, aligned to Georgia’s K-12 Mathematics Standards. Items are grouped into the domains Operations and Algebraic Thinking, Number and Operations in Base Ten, Number and Operations – Fractions, Measurement and Data, and Geometry.
How many questions are on Georgia Milestones Math?
Grade 3 GMAS Math has roughly 50-60 items split across two test sections, given on separate days. Each section runs about 70-85 minutes, though most students finish well before time runs out. The exact item count varies by year.
Is Georgia Milestones paper-based or online?
GMAS is fully online for all Georgia districts (Georgia transitioned to all-digital testing). A few students take paper versions as a documented accommodation. Have your child practice on a tablet or laptop so the testing interface isn’t new on test day.
What question types appear on the test?
Multiple choice (selected response), multi-select, drag-and-drop, equation builder, and constructed-response items where your child shows work or writes a short explanation. Roughly a third of the test is non-multiple-choice.
Is a calculator allowed?
No – calculators aren’t allowed on grade 3 GMAS Math. A formula sheet isn’t typically provided at grades 3-5 either, so your child needs solid mental math and recall of basic facts and conversions.
What’s a passing score?
GMAS reports four achievement levels: Beginning Learner, Developing Learner, Proficient Learner, and Distinguished Learner. “Proficient” is the state’s grade-level target. The cut score varies by year, but at grade 3 Math, Proficient is typically around 525 on the scale score.
When is the test given?
GMAS for grades 3-8 is given in the spring, usually April or early May. Your district sets the exact window. Both grade-level sections happen within a one- to two-week stretch.
How should we prep for GMAS Math?
Three habits help most: (1) 15-20 minutes of focused practice four or five days a week, (2) one full-length practice test a couple of weeks out, and (3) reviewing every missed item together to spot real gaps. The Top 10 questions on this page are a quick check on what to expect.
What’s the constructed-response item about?
At grade 3, GMAS includes one or two constructed-response items where your child shows work or explains thinking in writing. Partial credit is awarded – even if the final answer is off, clear work can earn points. Practice writing one or two sentences of reasoning per problem.
Where can my child get more GMAS practice?
