Passage: 'Our school should plant a vegetable garden. Students would learn about science, eat fresh produce, and work together. Let's ask our principal to support this project!'
What is the author's purpose? Which statement most clearly reveals it?
Persuade. 'Our school should plant a vegetable garden' presents the author's position, and the last sentence calls readers to action.
Passage: Sea turtles travel thousands of miles through oceans. Female sea turtles often return to the same beaches where they hatched to lay eggs. After hatching, baby turtles must make their way to the ocean while avoiding predators.
Which statement BEST summarizes the passage?
Sea turtles travel long distances and face challenges as they reproduce and begin life.
A science article explains that melting mountain snow filled a river with more water than usual. As a result, nearby fields flooded.
Identify the text structure and explain how the ideas are connected.
Cause and effect. Melting snow increased river water (cause), which led to flooding (effect).
“After several days of heavy rain, the river began to overflow. The water caused an interruption in traffic because the bridge was unsafe to cross.”
What does *interruption* mean in this passage? Explain how the root **rupt** helps you determine the meaning.
Interruption means a break or temporary stop in something. Rupt means break or burst. Traffic could not continue normally.
Passage: 'During a dry summer, the town's reservoir became unusually low. Residents were asked to water lawns less often and take shorter showers.'
Why did town leaders likely ask residents to conserve water? Use TWO details as evidence.
There was a possible water shortage because the summer was dry and the reservoir level was unusually low.
Passage: 'The new playground is a wonderful improvement. The climbing structures are safer, and the shaded benches make recess more enjoyable.'
What is the author's purpose
To inform
Passage: Wetlands absorb extra rainwater and help reduce flooding. Their plants filter pollutants from water. Wetlands also provide homes for frogs, birds, and fish. Some communities have drained wetlands to build roads and houses.
What is the central idea, and which TWO details best support it?
Central idea: Wetlands are important environments that benefit nature and communities. Details: They reduce flooding, filter water, and provide wildlife habitats. Any two work.
A textbook includes a map of Madagascar, a caption describing lemur habitats, and a paragraph about how lemurs survive in forests.
Which text feature is MOST useful for finding WHERE lemurs live, and how does it help the reader?
The map, because it visually shows the geographic location; labels or a map key can help the reader identify specific areas.
“Scientists photographed a newly discovered insect. Later, they created a diagram to show the insect's body parts. Their work helped other researchers study the tiny creature.”
The words *photographed* and *diagram* contain roots students have studied. Identify **photo** and **graph**, explain their meanings, and describe how both connect to recording or presenting information.
Photo means light, and graph means write, draw, or record. A photograph records an image using light; a diagram visually represents information through a drawing.
Passage: 'The fox crept toward the rabbit. Its paws moved softly across the grass. Suddenly, a twig snapped beneath one paw, and the rabbit darted into its burrow.'
What can you infer about why the fox failed to catch the rabbit? Identify TWO supporting details.
The snapping twig likely alerted the rabbit. The fox had been moving quietly, but the twig snapped and the rabbit immediately ran into its burrow.
Passage: 'Every student deserves more outdoor learning time. Studies suggest that outdoor experiences can encourage curiosity. School leaders should schedule at least one outdoor lesson each week.'
Is the author primarily informing or persuading? Explain how factual information is used to support the author's purpose.
Persuading. The author uses a statement about research to support the recommendation that schools provide weekly outdoor lessons.
Passage: Honeybees visit flowers to collect nectar. As they move, pollen sticks to their bodies and travels to other flowers. This helps many plants produce seeds. Without pollinators, some plants would produce fewer fruits and seeds.
Which sentence would be the BEST conclusion to strengthen the passage's main idea? Explain.
Example: Honeybees are important because their pollination helps plants reproduce and produce food.
Passage: 'Plastic waste enters the ocean and can harm sea animals. One solution is to reduce single-use plastics. Communities can also organize shoreline cleanups.'
Identify the primary text structure. Explain why it is more accurate than sequence.
Problem and solution. Ocean plastic pollution is the problem; reducing plastics and cleanups are solutions. The paragraph does not give steps in an ordered procedure.
“After a small earthquake, scientists examined a crack in the ground. They explained that a fracture in the rocks beneath Earth's surface caused part of the ground to shift.”
The words *terrain* and *fracture* are related to two roots we studied: **terr** and **rupt**. Which root BEST connects to the ground being studied, and which connects to the rocks breaking? Explain your choices.
Terr means Earth or land and connects to terrain or ground. Rupt means break or burst and connects conceptually to rocks breaking. Note: fracture itself contains the root fract, not rupt.
Passage: 'After a wildfire, blackened tree trunks remained across the hillside. The following spring, green shoots appeared. Some seeds had remained dormant until heat from the fire helped open their cones.'
A student claims, 'Wildfires always destroy an ecosystem permanently.' Does the passage support or challenge this claim? Use evidence.
It challenges the claim. The new green shoots and heat-released seeds show that some plants can recover or reproduce following a wildfire.
Every year, thousands of plastic bottles end up in rivers and oceans. These bottles can harm marine animals and pollute their habitats. By using reusable water bottles, students can help reduce plastic waste. Schools should encourage every student to bring a reusable bottle instead of purchasing disposable ones.
The author's primary purpose is to persuade readers to use reusable water bottles.
