Free 3rd Grade Star Sample Questions with Explanations

The correct answer is (B).

What is an idiom? An idiom is a group of words that means something different from what the words say by themselves. For example, if someone says "it's raining cats and dogs," animals aren't really falling from the sky! It means it's raining very hard. To understand an idiom, we look for clues in the text.

Step 1: Read the text and find out what happened. Let's look at what happened to Sarah:

• Her bus was late, so she missed the beginning of the party.
• But she still came to the party.
• She joined the games and had a wonderful time.

Step 2: Look at the words in the idiom. Mom says, "Better late than never!" Let's think about two important words:

• Late: Sarah came to the party late.
• Never: Sarah could have never come to the party at all.

Now ask yourself: what was better for Sarah, coming late or never coming?

Step 3: Use the text to figure out the meaning. Sarah came late, but she still had a wonderful time. If she had never come, she would have missed all the fun! So coming late was better than not coming at all. This means the idiom "better late than never" means: it is better to do something late than not to do it at all. Therefore, the correct answer is (B).

Step 4: Understand why the other answers are wrong.

• Answer (A) is incorrect. It's true that being on time is a good idea, but that's not what the idiom means. The idiom tells us that coming late is still better than not coming at all.
• Answer (C) is incorrect. Sarah had fun, but that doesn't mean everyone who comes late will have more fun. Watch out for words like "everyone." They often make an answer wrong!
• Answer (D) is incorrect. To "regret" something means to feel sorry about it and wish it had happened differently. But the text says Sarah had a wonderful time. Nothing in the text shows she felt sorry about coming late.

Tip: When you see an idiom, don't just read the words one by one. Look at the sentences around it to figure out what the idiom really means!

The correct answer is A. 

Step 1: What is a “main idea”? 
The main idea is what the whole text is mostly about. It’s the big idea that all the sentences share. Think of it like an umbrella: every detail in the text fits underneath it. 

Step 2: Ask yourself, “What is this text about?” 
Every sentence in this text talks about yoga and kids. So we know the text is about yoga for kids. 

Step 3: Look for the details. 
Now let’s see what the text tells us about yoga for kids: 

• It helps kids’ bodies bend, balance, and move well. 

• It helps kids pay attention and feel good about themselves. 

• It helps kids feel calm when they are stressed. 

• It helps kids be creative and stay healthy. 

Step 4: Put the details together. 
What do all these details have in common? They are all positive things that yoga does for kids. So the main idea is: yoga is good for kids in many different ways and the correct answer is A. 

Step 5: Check the answer choices. 
Answer (B) is incorrect. While yoga can indeed be practiced by individuals of all ages, the text specifically focuses on its benefits for children. It doesn’t extensively discuss its suitability for all age groups, making this answer overly broad and not fully capturing the main idea centered around kids. 

Answer (C) is incorrect. The text doesn’t emphasize that the physical activity challenge of yoga is greater than the mental challenge for kids. Instead, it highlights how yoga helps kids focus their concentration, and promotes mental well-being, indicating that the mental challenge is significant as well. As a result, this answer doesn’t reflect the main idea of the text. 

Answer (D) is incorrect. In the last line, we read that yoga fosters a healthy lifestyle. However, this doesn’t mean that yoga is the only way for kids to stay healthy, or that all healthy kids practice yoga. 

The correct answer is (C). 

What is this question asking? This question asks about a detail, a small fact that the text tells us. To answer it, we don’t need to guess. We just need to find the right sentence in the text and read it carefully. 

The word “involve” means “a part of something.” So the question is asking: What things are part of doing yoga? 

Step 1: Find the sentence that answers the question. Look back at the text. The second sentence says: 
“It involves a series of stretches, poses, and breathing exercises...” 
Look, the word “involves” is right there! This is the sentence we need. 

Step 2: List what the sentence tells us. Yoga is made of three things: 

1. Stretches 
2. Poses (a pose is a way of holding your body, like standing on one leg) 
3. Breathing exercises 

So yoga is a mix of different activities, not just one. 

Step 3: Check the answer choices.

Let’s find the answer that includes all three things. 

Answer (A) is incorrect. While breathing exercises are an important component of yoga, they are not the main focus of the practice, as yoga involves a combination of exercises. It’s not mentioned in the paragraph which of them is exercised more. 

Answer (B) is incorrect. Physical stretches are a significant part of yoga, but they are complemented by poses and breathing exercises. 

Answer (D) is incorrect. While yoga encourages imagination and creativity, the primary focus of yoga practice extends beyond these aspects.  Additionally, the passage doesn’t provide information about any specific exercise being more important than others.  

Answer (C) is correct because it names all three: stretches, poses, and breathing exercises.

Tip: Watch out for words like “only” and “mainly.” They often make an answer too narrow. The right answer should match everything the text says.

Correct answer: A.

Step 1: Find the clue in the text. The last sentence says: "Ben smiled."

Step 2: Think about what the clue tells us. People smile when they are happy. Ben helped the bird, and now it could fly again.

Step 3: Check the answer choices. Answers (B), (C), and (D) are wrong because nothing in the text shows that Ben was angry, bored, or afraid.

Tip: When a question asks how a character feels, look for what the character does or says. A smile is a clue.

The correct answer is C.

Step 1: Read what the question gives us. There are 4 boxes, and each box has 6 pencils. That means there are 4 groups, and each group has 6 pencils.

Step 2: Add the groups. 6 + 6 + 6 + 6 = 24.

Step 3: Use multiplication. Adding the same number again and again is the same as multiplying: 4 × 6 = 24.

Step 4: Check the answer choices.

• Answer (A) is incorrect. It adds 4 and 6, but the question asks for 4 groups of 6.
• Answers (B) and (D) are incorrect. They are 4 × 5 and 4 × 7, so they use the wrong number of pencils in a box.

The correct answer is (B).

Step 1: Picture a pizza. Cut the pizza into 4 equal slices. 2 of the 4 slices are half of the pizza.

Step 2: Write it as a fraction. 2 slices out of 4 is 2/4, so 2/4 = 1/2.

Step 3: Check the answer choices.

• Answer (A) is incorrect. 1/3 is one of 3 equal parts, which is less than half.
• Answers (C) and (D) are incorrect. 2/3 and 3/4 are both more than half.

The correct answer is (B).

What is perimeter? The perimeter is the distance all the way around the outside of a shape. Imagine an ant walking along the edge of the house until it comes back to where it started. The perimeter is how far the ant walked.

Step 1: Look at the shapes. The house is made of two shapes: a square at the bottom and a triangle on top.

Step 2: Find the length of each side. (Show image2.png, the house with every side labeled 2 cm.)

• In a square, all 4 sides are the same length. The question says one side is 2 cm, so every side of the square is 2 cm.
• The triangle is equilateral. That means all 3 of its sides are the same length. The bottom of the triangle sits on top of the square, so it is also 2 cm. That means every side of the triangle is 2 cm too.

Step 3: Find the outside sides. (Show image3.png, the house outline with the inside line crossed out.) Put your finger on the bottom of the house and trace all the way around the outside. Count the sides as you go:

• The bottom of the square
• The right side of the square
• The right side of the roof
• The left side of the roof
• The left side of the square

There are 5 outside sides. What about the yellow line between the square and the triangle? It is inside the house, so the ant never walks on it. That's why it has an ✗. We don't count it!

Step 4: Add the sides together. Every side is 2 cm, and there are 5 sides: 2 + 2 + 2 + 2 + 2 = 10. The perimeter of the house is 10 cm. The correct answer is (B).

Why are the other answers wrong?

• Answer (A) is incorrect because 6 is the perimeter of only the triangle (2 + 2 + 2). But the question asks about the whole house.
• Answer (C) is incorrect because 12 counts the line between the square and the triangle. That line is inside the house, so it is not part of the perimeter.
• Answer (D) is incorrect because 14 adds the square (8) and the triangle (6) separately. When we do that, the middle line gets counted twice, but it shouldn't be counted at all.
