- Read the paragraph. Erosion happens when water or wind wears away soil and rocks. After a big rain, you might see dirt washed into a stream. Over many years, this process can make hills smaller and riverbanks change shape. Erosion is slow, but it can change land a lot. In this text, what does erosion mean?
Answer: when water or wind wears away land
This question tests determining meaning of academic and domain-specific words from context (CCSS.RI.3.4: Determine the meaning of general academic and domain-specific words and phrases in a text relevant to a grade 3 topic or subject area). Students must use context clues in the passage to figure out what the vocabulary word means. Academic words are general terms used across different subjects (process, evidence, demonstrate, identify). Domain-specific words are technical terms used in particular subject areas - science (metamorphosis, erosion, habitat), social studies (peninsula, democracy, citizen), math (polygon, perimeter, fraction), arts (orchestra, harmony, rhythm). To determine word meaning from context, look for: definitions in the text, examples that show meaning, descriptions that explain the word, restatements using different words, or contrasts with opposite meanings. Students should not guess based on parts of the word or what they think it might mean - they must use the information in the passage. In this passage about changes to land over time, the word erosion appears in the context of natural processes affecting soil and rocks. The passage provides context clues: a direct definition and examples. For example, it states 'Erosion happens when water or wind wears away soil and rocks' and gives examples like 'dirt washed into a stream' and 'hills smaller and riverbanks change shape.' Choice B is correct because it directly matches the definition provided in the passage. The passage defines erosion as when water or wind wears away land, and the examples of rain washing dirt and changing landforms show that erosion means a gradual wearing away process. The text directly states that 'Erosion happens when water or wind wears away soil and rocks,' confirming this meaning fits how the word is used in the passage. Choice A is incorrect because it confuses erosion with earthquake, which is a different geological event. This is a common meaning mix-up, but in this passage, erosion has a specific science meaning related to gradual wearing away, not sudden shaking. This error occurs when students don't use context clues and rely on partial understanding or confuse related terms like natural disasters. To help students: Explicitly teach context clue types (definition = word is defined, example = examples show meaning, description = details explain meaning, restatement = word restated differently, contrast = opposite helps clarify). Model think-aloud: 'I don't know what erosion means. Let me read around it carefully. The text says erosion happens when water or wind wears away soil and rocks. That tells me erosion means when water or wind wears away land.' Practice with subject-area texts where students circle unknown words, underline context clues, and determine meanings. Create content-area word walls organized by subject (science words, social studies words, math words, arts words). Teach students to: (1) Read the whole sentence with unknown word, (2) Look for definition, examples, or description, (3) Try the meaning in place of unknown word to check if it makes sense, (4) Verify with dictionary if needed. Pre-teach key domain-specific vocabulary before reading, but also practice determining meanings from context. Watch for: Students who skip unknown words, guess based on word parts only, use wrong meaning (everyday vs. technical), or don't look for context clues. Provide explicit instruction in using context and repeated practice with informational texts.
- Based on the passage, what does the word metamorphosis mean?
Answer: The full path an animal takes from one body form to the next as it develops
The passage shows a butterfly turning into different forms one after another: egg, caterpillar, chrysalis, and adult. That whole set of changes from one body form to the next is what metamorphosis means, so the full path an animal takes as it develops is the best answer. The choice about a hidden resting spot matches the chrysalis in the story, but that names a place, not the whole change. The choice about special leaves and foods talks about what a caterpillar eats, not what the word means. The choice about a loud warning sound has nothing to do with a body changing shape. Only one answer describes the process of changing forms, so it is the correct meaning.
- Read the text. Butterflies go through metamorphosis. They change from egg to caterpillar to chrysalis to adult butterfly. What does the word metamorphosis mean in this text?
Answer: a change from one form to another
The word metamorphosis means a change from one form to another. You can tell this from the text, which shows the butterfly changing from egg to caterpillar to chrysalis to adult. Each stage is a different form, so the word describes that changing.
The answer about a long, deep sleep through winter is wrong. That describes hibernation, which is when animals sleep through the cold. The butterfly in the text is changing, not sleeping.
The answer about a way animals hunt and find their food is wrong. The text says nothing about hunting or eating. It only tells about the butterfly's stages of growth.
The answer about a safe place where animals build homes is wrong. Metamorphosis is not a place at all. It is something that happens to the butterfly's body as it grows and changes.
- In this passage, what does the word polygon mean?
Answer: A closed shape made from straight edges joined at corners
The passage says a polygon is a flat shape with straight sides, and it lists triangles, squares, and pentagons as examples. So the best meaning is a closed shape made from straight edges joined at corners. The choice about a round shape with a smooth curving edge describes a circle, which the passage clearly says is NOT a polygon. The choice about a single straight line that never closes up is wrong because a polygon is a closed shape, not an open line. The choice about a flat shape with just one long side and no corners cannot be right either, because polygons like triangles and squares have several straight sides that meet at corners.
- What does the word evaporates mean in this text?
Answer: changes into a gas and rises into the air
The text says the Sun heats the water and then the water rises into the air. Heating turns liquid water into a gas that floats up, so evaporates means changes into a gas and rises into the air. Freezing into hard ice is wrong because that happens when water gets very cold, not hot. Soaking down into the ground is wrong because the text shows the water going up into the air, not down. Flowing into a river is wrong because that is water moving along the ground, not turning into a gas from the Sun's heat.
- In the passage, what does the word peninsula mean?
Answer: Land that has water along three of its sides
A peninsula is land that has water along three of its sides, just like Florida, which has water on its east, west, and south sides and land only on the north. The choice about land completely surrounded by ocean is wrong because that would be an island, with water on all sides, not three. The choice about land connecting two larger areas of water describes a narrow strip called an isthmus, not a peninsula. The choice about land sitting high above the water in hills is wrong because a peninsula is about which sides have water, not about how tall the land is. Only the answer about water along three sides matches what the passage tells us about Florida.
- Based on the text, polygon means:
Answer: a flat shape made with straight sides that connect
The text tells us a polygon is a closed shape with straight sides, like a triangle, square, or pentagon. So a polygon is a flat shape made with straight sides that connect. The choice about curved sides that never touch is wrong because a circle has curved sides and is NOT a polygon. The choice mixing straight and curved sides is wrong because a polygon has only straight sides, not curved ones. The choice about only one long straight side is wrong because a polygon needs several straight sides that connect to make a closed shape. Only the first choice matches every clue in the text.
- Read the text. A peninsula is a landform that is surrounded by water on three sides. Florida is a peninsula in the United States, with water along much of its edge. You can see it sticking out into the ocean on a map. According to the text, what is a peninsula?
Answer: a piece of land with water touching it on three of its sides
The text tells you a peninsula is a landform with water on three sides, and it uses Florida as an example that sticks out into the ocean. The best answer is the piece of land with water touching it on three of its sides, because that matches the meaning the text gives you. The choice about land with water touching only one side is wrong because the text clearly says three sides, not one. The choice about a river flowing across the middle is wrong because a peninsula has water around its edges, not a river cutting through it. The choice about a body of water with land wrapped around every side is wrong because a peninsula is land, not water, and it is not surrounded on all sides. Read the whole sentence, look for the definition, and try your answer in place of the word to check that it makes sense.
- Based on the passage, what does the word matter mean?
Answer: any real stuff that has weight and fills up room
The passage tells us that matter is anything that takes up space and has weight, and it gives examples like a rock, a pencil, and air. So the best meaning is any real stuff that has weight and fills up room. The choice about a problem or trouble uses an everyday meaning of the word 'matter,' but that is not how this science passage explains it. The choice about a force that pulls objects down describes gravity, which is a different science idea and is never mentioned here. The choice about paint that artists use has nothing to do with taking up space or having weight, so it does not fit the passage at all. Only one meaning matches what the passage actually says about matter.
- Read the paragraph. A habitat is the place an animal lives and finds what it needs. For example, a pond habitat can give a frog water, plants, and insects to eat. In the passage, what does habitat mean?
Answer: an animal's home area that supplies its food, water, and shelter
The paragraph tells you what habitat means and gives an example. It says a habitat is where an animal lives and finds what it needs, and the pond example shows a frog getting water, plants, and insects. So habitat means an animal's home area that supplies its food, water, and shelter. The choice about a yearly trip to a warmer place describes migration, which is how some animals move, not where they live and find what they need. The choice about weather and temperature all year describes climate, not a home; the pond in the passage gives an animal things it needs, not a kind of weather. The choice about a group that hunts together describes a pack of animals, not the place where an animal lives. Only one choice matches the meaning the passage gives, so that is the best answer.
- Based on the text, numerator means:
Answer: the number above the line in a fraction, which tells how many parts are chosen
The text says the numerator is the top number and that it tells how many parts you have. In the example three-eighths, the numerator 3 tells you that three parts are chosen. So the numerator is the number above the line that tells how many parts are chosen. The choice about the bottom number is wrong because that number tells how many equal parts there are in all, not how many are chosen. The choice about adding the two numbers together is wrong because a numerator is not an answer to a math problem, and the text never says to add. The choice about the small straight line is wrong because that line only separates the two numbers; it is not itself a number.
- In the passage, what does habitat mean?
Answer: the home area where an animal lives and finds everything it needs
A habitat is the place where a living thing lives and gets what it needs, like the frog's pond with water, plants, and bugs. So the best meaning is the home area where an animal lives and finds everything it needs. The choice about bugs and food names only one thing the frog finds in its habitat, not the whole place. The choice about pond water also names just one part of the pond, not the full habitat. The choice about a trip to a new place describes what happens if the habitat dries up, not what the word habitat means. Only one answer covers the whole place where an animal lives and gets what it needs.
- Based on the passage, what does the word erosion mean?
Answer: when water or wind slowly breaks down land over time
The passage says erosion happens when water or wind wears away land over many years, making hills smaller and carrying sand into rivers. The best answer matches this: water or wind slowly breaking down land over time. One choice says the ground shakes and cracks apart, but the passage describes slow wearing away, not sudden shaking. Another says land builds up higher, which is the opposite of wearing away and making hills smaller. The last choice talks about rain flooding and covering land, but erosion removes and carries land away, it does not cover it. Only one choice fits what the passage tells us about erosion.
- Read the paragraph. A polygon is a closed shape with straight sides. Triangles, squares, and pentagons are all polygons. The word polygon in this text means:
Answer: a closed shape with straight sides
This question tests determining meaning of academic and domain-specific words from context (CCSS.RI.3.4: Determine the meaning of general academic and domain-specific words and phrases in a text relevant to a grade 3 topic or subject area). Students must use context clues in the passage to figure out what the vocabulary word means.

Students should not guess based on parts of the word or what they think it might mean - they must use the information in the passage. In this passage about mathematics, the word 'polygon' appears in the context of geometric shapes. The passage provides context clues through definition and examples. The text states 'A polygon is a closed shape with straight sides' and gives examples: 'Triangles, squares, and pentagons are all polygons.' Choice B is correct because it matches the definition provided in the text. The passage directly defines polygon as 'a closed shape with straight sides.' The examples of triangles, squares, and pentagons all support this definition - they are all closed shapes made of straight sides. This meaning fits with how the word is used in the passage. Choice A is incorrect because it describes only triangles, not all polygons. This is incomplete - it doesn't capture the full meaning provided by the context. While triangles are polygons, the passage makes clear that polygons include many shapes (triangles, squares, pentagons), not just three-sided shapes. This error occurs when students focus on one example rather than understanding the complete definition. To help students: Explicitly teach context clue types (definition = word is defined, example = examples show meaning, description = details explain meaning, restatement = word restated differently, contrast = opposite helps clarify). Model think-aloud: 'I don't know what polygon means. Let me read around it carefully. The text says a polygon is a closed shape with straight sides. That tells me polygon means any closed shape with straight sides, not just triangles.' Practice with subject-area texts where students circle unknown words, underline context clues, and determine meanings.

- Read the paragraph. Friction is a force that slows motion when two surfaces rub together. For example, your shoes grip the floor so you do not slip. But friction can also make it harder to slide a box across the carpet. In this text, what does friction mean?
Answer: a force that makes moving objects slow down when they rub
The paragraph tells you that friction slows motion when two surfaces rub together. The examples help you check this: your shoes rub the floor and grip so you do not slip, and a box rubs the carpet so it is hard to slide. Both examples show rubbing surfaces slowing things down, so the best meaning is a force that makes moving objects slow down when they rub. The choice about a force pushing objects up to float is wrong because friction does not lift things or make them float; it happens when surfaces touch and rub. The choice about magnets pulling together is wrong because magnetism, not friction, pulls magnets, and friction needs surfaces rubbing, not attracting from a distance. The choice about objects falling straight down describes gravity, not friction, since friction is about rubbing surfaces, not pulling things toward the ground. Only one meaning matches both examples in the paragraph.
- Read the text. A lever is a simple machine that helps lift heavy objects. It has a fulcrum, or pivot point, where the lever rests and turns. When you push down on one end, the other end lifts up. In the passage, what does fulcrum mean?
Answer: the balance point that a lever rests on and turns around
The passage tells you that a fulcrum is a 'pivot point, where the lever rests and turns.' A pivot point is the balance point a lever rests on and turns around, so that is the best meaning. The long bar you push down on is a different part of the lever, not the point it turns around. A wheel that rolls belongs to another kind of machine and is not where a lever pivots. The heavy load is the object the lever lifts, not the point it turns on. When you use the clues around the word, only the balance point that the lever rests on and turns around fits what the text says.
- Read the text. Erosion happens when water or wind wears away soil and rocks. This process can make hills smaller and can carve new paths for rivers over time. After a big storm, you might notice dirt moved from one place to another. What does the word erosion mean in this text?
Answer: the slow wearing away of land by moving water or wind
The text tells you erosion happens when water or wind wears away soil and rocks, and it gives examples: hills getting smaller and dirt moving after a storm. So the best meaning is the slow wearing away of land by moving water or wind. "The ground suddenly shakes and cracks open" describes an earthquake, but the text shows erosion happens slowly over time, not all at once. "A very hard kind of rock that never breaks apart" is the opposite of erosion, which is about land being worn away, not staying hard. "Clouds fill with water and let rain fall" describes rain, which is not the same as wind or water wearing land away. Use the definition and the examples in the text to check that only one choice fits.
- Read the text. An orchestra is a large group of musicians who play together. It can include string instruments like violins, brass instruments like trumpets, and percussion like drums. A conductor stands in front to lead the group. What does the word orchestra mean in this text?
Answer: many musicians who play their instruments together
The text tells you exactly what an orchestra is. It says an orchestra is a large group of musicians who play together, and it gives examples like violins, trumpets, and drums. A conductor even stands in front to lead everyone. So the best meaning is many musicians who play their instruments together. "One musician who writes songs alone at home" is wrong because an orchestra is a big group, not one person working alone. "One drummer who keeps the beat for a band" is wrong because a drummer is only one part of the group, not the whole orchestra. "A quiet room where framed paintings are displayed" is wrong because that describes an art gallery, which has nothing to do with musicians playing music. Only one choice matches the group of musicians the text describes.
- What does the word orchestra mean in this text?
Answer: many musicians who perform different instruments as one team
The text tells you an orchestra is a big group of people who play many instruments together, like violins, trumpets, and drums. That is why 'many musicians who perform different instruments as one team' is the best meaning. 'One singer performing a song without any instruments' is wrong because an orchestra is a whole group, not one person, and they play instruments instead of just singing. 'A single kind of instrument, such as the violin or trumpet' names only one part of the orchestra, but the word means the whole group of many different instruments. 'A special stage where music concerts are held' points to a place, but an orchestra is the group of musicians, not the room or stage where they play. So the group of musicians playing together is the only choice that fits.
- Based on the text, what does denominator mean?
Answer: the number on the bottom that shows how many equal parts make the whole
The passage explains that the denominator is the bottom number of a fraction, and it tells how many equal parts make up the whole. That matches the choice about the bottom number showing how many equal parts make the whole. The choice about the top number is describing the numerator, which counts the parts you are actually using, not the total parts. The choice about a line that means add is wrong because a fraction bar does not tell you to add; it separates the two numbers. The choice about counting the sides of a shape mixes up a fraction with a shape like a square, which is not what a denominator means. Only one choice fits the bottom number that names the total equal parts.
