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, 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 on the STAAR grade 3 mathematics reference materials?

The grade 3 STAAR mathematics reference materials include a ruler printed on the page and a short list of formulas and measurement facts third graders may need, such as perimeter. TEA posts the current sheet on its website. Print it and have your child use it while practicing, so on test day they know exactly what is there and what they must remember.

Is there a STAAR grade 3 math practice test?

Yes. TEA offers an online STAAR grade 3 mathematics practice assessment, and this 20-question set is a good paper warm-up before it. Third graders work without a calculator, so mental math and written strategies matter. Try items like 55 × 14: break it into 55 × 10 = 550 plus 55 × 4 = 220, for a total of 770.

Where can I find the STAAR grade 3 math answer key?

Answer keys for released STAAR grade 3 math tests and for the practice assessment are posted by the Texas Education Agency next to each test. After your child finishes, check answers together and talk about why each wrong choice is wrong. For example, three $10 spaghetti plates and two $6 soups cost $30 + $12 = $42, not $16.

What is the STAAR grade 3 math blueprint?

The blueprint is TEA’s outline of how many questions come from each reporting category on grade 3 STAAR math: numerical representations and relationships, computations and algebraic relationships, geometry and measurement, and data analysis with personal financial literacy. It shows where most points come from, so you can put more practice time on computation and place value, like rounding 745 to 750.

Where can I find STAAR grade 3 mathematics released test questions?

TEA publishes released STAAR grade 3 math tests from past years as PDFs, which you can print for practice at home. The newest ones show the redesigned item types, such as typing a number answer instead of choosing one. Mix them with quick fact checks, like 18 boxes of 40 crayons making 720 crayons, to build speed and accuracy.
