10 Sample 3rd Grade IAR Math Practice Questions
Classroom \(A\) contains \(8\) rows of chairs with \(4\) chairs per row. If classroom \(B\) has three times as many chairs, which number sentence can be used to find the number of chairs in classroom \(B\)?
\(8 × 4 + 3\)
\(8 + 4 × 3\)
\(8 × 4 × 3\)
\(8 + 4 + 3\)
Show answer and explanation
C
\(3\) times of \(8\) rows of chairs with \(4\) chairs per day are: \(3 × 8 × 4\)
A cafeteria menu had spaghetti with meatballs for \($8\) and bean soup for \($6\). How much would it cost to buy three plates of spaghetti with meatballs and three bowls of bean soup? __________
Show answer and explanation
42
\(3\) spaghetti with meatballs cost: \($3 × $8 = $24\)
\(3\) bowls of bean soup cost: \(3 × $6 = $18\)
\(3\) spaghetti with meatballs \(+ 3\) bowls of bean soup cost: \($24 + $ 18 = $42\)
There are \(7\) days a week. There are \(24\) hours in a day. How many hours are in a week?
\(48\)
\(96\)
\(168\)
\(200\)
Show answer and explanation
C
\(1\) day: \(24\) hours so \(7\) days \(= 7 × 24 = 168\) hours
Emily described a number using these clues:
Three-digit odd numbers that have a \(6\) in the hundreds place and a \(3\) in the tens place
\(627\)
\(637\)
\(632\)
\(636\)
Show answer and explanation
B
Three-digit odd numbers that have a \(6\) in the hundreds place and a \(3\) in the tens place is \(637\), \(632\) and \(636\) are even numbers.
This clock shows a time after \(12:00 PM\). What time was it \(1\) hour and \(30\) minutes ago?
\(12:45 PM\)
\(1:45 PM\)
\(1:15 PM\)
\(12:15 PM\)
Show answer and explanation
A
Subtract hours: \(14– 1 = 13\)
Subtract the minutes: \(15 – 30 = -15\)
The minutes are less than \(0\), so:
• Add \(60\) to minutes ( \(-15 +60 =45\) minutes)
• Subtract \(1\) from hours \((13 – 1 =12)\)
Olivia has \(84\) pastilles. She wants to put them in boxes of \(4\) pastilles. How many boxes does she need?
\(20\)
\(21\)
\(24\)
\(28\)
Show answer and explanation
B
Olivia wants to divide \(84\) pastilles into boxes of \(4\) pastilles, so \(84 ÷ 4 = 21\) is the number of boxes.
A football team is buying new uniforms. Each uniform costs \($20\). The team wants to buy \(11\) uniforms.
Which equation represents a way to find the total cost of the uniforms?
\((20 × 10) + (1 × 11) = 200 + 11\)
\((20 × 10) + (10 × 1) = 200 + 10\)
\((20 × 10) + (20 × 1) = 200 + 20\)
\((11 × 10) + (10 × 20) = 110 + 200\)
Show answer and explanation
C
The football team should buy \(11\) uniforms that each uniform cost \($20\) so they should pay\((11×$20) $220\).
Therefore, choice C is the correct answer:
\((20 × 10) + (20 × 1) = 20(10+1) =20×11=220\)
There are \(92\) students from Lexington Elementary School at the library on Tuesday. The other \(54\) students in the school are practicing in the classroom. Which number sentence shows the total number of students in Riddle Elementary School?
\(92 + 54\)
\(92 -54\)
\(92 × 54\)
\(92 ÷54\)
Show answer and explanation
A
Add \(92\) and \(54\) students to know the whole number of students.
Use the picture below to answer the question.
Which fraction shows the shaded part of this square?
\(\frac{92}{100}\)
\(\frac{92}{10}\)
\(\frac{90}{100}\)
\(\frac{8}{100}\)
Show answer and explanation
A
The model for the fraction is divided into \(100\) equal parts. We shade \(92\) parts of these \(100\) parts that it’s equal to \(\frac{92}{100}\)
