Keisha wrote about pulleys: "A flagpole uses a pulley. A crane uses a pulley." Which transition fits?
- In contrast
- For instance (correct answer)
- Therefore
- Before
Explanation: This question tests 4th grade informational/explanatory writing skills: linking ideas within categories of information using words and phrases like another, for example, also, because (CCSS.W.4.2.c). Informational and explanatory writing needs transitional words and phrases to link ideas within categories of information. These transitions show relationships between related ideas and help readers follow connections. Common transitions: addition (also, another, in addition, furthermore—when adding related information: 'Camels store water. They also have long eyelashes.'), example (for example, for instance, such as—when giving instances: 'Desert animals have adaptations. For example, camels store water.'), comparison (similarly, likewise, in the same way—when showing similarity: 'Camels have humps. Similarly, beavers store fat.'), contrast (however, on the other hand, unlike—when showing difference: 'Summer is hot. However, winter is cold.'), cause-effect (because, therefore, as a result—when showing why/result: 'Exercise builds muscles. Therefore, it's important.'). Transitions match the relationship: if adding similar information, use also/another; if contrasting, use however; if giving example, use for example. Without transitions, writing is choppy: 'Camels have humps. They have eyelashes. They have wide feet.' With transitions: 'Camels have several adaptations. They store water in their humps. They also have long eyelashes to protect eyes from sand. Another adaptation is their wide feet.' Transitions make relationships clear. Keisha writes about pulleys in simple machines, including related ideas within the category like flagpole and crane as examples of pulley uses. The writing lacks transitions, with sentences about similar examples needing a linking word to show one is an instance of the category. Choice B is correct because 'for instance' fits by providing an example, connecting the flagpole and crane as related instances within the pulley uses category. Choice A is incorrect because 'in contrast' shows difference, but the pulley examples are similar; students sometimes confuse contrast transitions with example ones when ideas are related. To help students use transitions to link ideas within categories: teach relationship-based transition categories explicitly with examples; create transition reference chart organized by purpose: addition (also, another, in addition), example (for example, for instance), comparison (similarly, likewise), contrast (however, unlike), cause-effect (because, therefore); model with think-aloud: 'I'm writing about camel adaptations—first feature: humps store water. Second feature: long eyelashes protect eyes. These are both physical features, so I need addition transition: They also have long eyelashes. Both are adaptations, so also works.' Practice 'match the transition': given two sentences about related ideas, which transition fits? (addition, example, contrast, etc.); use sentence frames: '[First idea]. [Transition] [related idea].' Provide feedback: 'These are both examples. Change 'however' to 'another' or 'for example.'' Use color-coding for related ideas that need transitions; practice combining choppy sentences: 'Polar bears have thick fur. They have small ears.' → 'Polar bears have thick fur. They also have small ears.' Show before/after: without transitions vs. with transitions; teach variety: 'You used 'and' five times. Try also, another, in addition.' Practice reading aloud—students hear when connections are missing; give categories of related information, ask students to connect items with appropriate transitions; use mentor texts—find transitions, discuss why author chose each one. Watch for: students who list information without using any transitions; students who use only one transition over and over (and...and...and); students who use wrong transitions for relationships (however when showing similarity). Watch for: students who think sequence transitions (first, next, then) work for all lists when they're only for steps in a process; students who don't vary transitions; students who put transition but connection is still unclear; students who confuse transitions within categories (W.4.2.c) with transitions between paragraphs; students who don't understand transitions show relationships between ideas.
