Several parents shared their children’s homework, that made them tilt their heads and call for help. Fortunately, some Reddit and Twitter users came to the rescue and shared their two cents.
The older one gets, the more complex educational work assigned to students gets. However, there are some instances where kids receive complicated homework.
When such instances arise, some parents seek the help of the online community to derive an answer for their little ones. Some of them are shared on the Reddit and Twitter platforms.
Grade 1 English
A mom was puzzled by her first-grade son’s English homework, where he had to encircle the photos that had the same ending sound as a fish’s fin. However, the options available were far from the picture. The available choices included a hamburger bun, a frog, a jar lid, and a spoon.
Some Reddit users offered their thoughts to the clueless mom, stating that the ending sound did not necessarily have to rhyme with fin. Some answers included bun and spoon, which both ended with an “n.”
Kindergarten School Work
Kindergarten homework questions are usually easy to answer with an adult’s help. However, one parent couldn’t think of the three-letter word required to name the picture printed on the activity sheet. The picture included a rabbit with her bunnies playing.
Fortunately, a kind Reddit user thought of the best possible answer: pet. “These kinds of worksheets try to make the last one more difficult by switching the sound of the letter to the end of the word to try and throw the kid off,” the person said.
Grade 3 Math Problem
Math problems for elementary students are often easily computed with all the numbers given in the problem. However, a Grade 3 student had to solve the question, “Janell had 15 marbles. She lost some of them. How many does Janell have now?”
One Reddit user suggested that the answer was less than 15 but did not think it was a fair question for someone in the third grade. Other users believed that the student should answer in a similar manner as the question, such as “Janell lost her marbles.” Another user said, “She has some left.”
A Six-Year-Old’s Homework
While some educational problems for six-year-olds are visual, one student’s assignment was beyond the comprehension of her parents. On her activity sheet appeared a print of a paint splatter and several apples.
The question read, “How many apples could be covered by the paint. There cannot be more than 20.” Several Reddit users were also confused by the question, while one believed it was a riddle.
Grade 1 Math
One Twitter user shared a Singaporean math problem for grade one students, and it seemed almost impossible to solve. However, one person solved the problem but tweaked the question a bit.
Another Math Problem
Another math question was posted on Twitter, leaving people confused. The question made students calculate the perimeter of a shape best on the calculations of another rectilinear shape.
One person replied to the post with a complicated answer and sarcastically said, “It’s very much justified to ask these to a [ten-year-old].”
Solving for X
Math can sometimes be complicated but often has one solution. However, this one math problem was too complex for the Twitter world.
“An orchestra of 120 players takes 40 minutes to play Beethoven’s 9th Symphony. How long would it take for 60 players to play the symphony? Let P be the number of players and T the time playing,” the question read. While it may be too complex, one Twitter person replied:
“The math is irrelevant in the case of this Beethoven 9 problem. As a performer who has performed it many times, the speed of the symphony is NOT a function of the number of musicians performing it.”
Reddit is one of the online forums people go to for questions. Previously, Reddit users shared 10 Intriguing Items That Perplex Observers with Their Form and Function.
IF YOU EVER SEE BLACK CABLES STRETCHING ACROSS THE ROAD, THIS IS WHAT YOU SHOULD DO
Unveiling the black road cables: Silent traffic observers capturing data for smarter road networks. Data-Driven Traffic Insights
As you navigate the highways and byways of your daily commute, you may have encountered an intriguing sight: black cables stretched across the road, almost like stealthy sentinels of the pavement. But what exactly are these enigmatic tubes, and what role do they play in our transportation infrastructure? The answer lies in the realm of traffic management and data collection.
These unassuming black cables are, in fact, portable traffic counters strategically placed by transportation authorities for research purposes. Primarily used by local agencies, these tubes hold vital insights into road usage and traffic patterns. With more than 12,000 of these traffic counters scattered across the state, they provide invaluable data that fuels the planning and development of our road networks.
Decoding the Mechanism Behind the Black Cables
The technology driving these unobtrusive rubber cords is elegantly simple yet remarkably effective.2 Each time a vehicle’s tires contact the tube, a burst of air is triggered, setting off an electrical signal recorded by a counter device. This ingenious pneumatic mechanism can track the volume of vehicles passing over a road within a given timeframe. Transportation agencies can gain insights into peak traffic congestion periods by analyzing the intervals between these air bursts. When deployed in pairs, these tubes provide even richer data, enabling the determination of vehicle class, speed, and direction.
Such information is far from trivial—it forms the bedrock for informed decisions on road signage, speed limits, and allocation of transportation budgets. Based on these insights, municipalities can fine-tune their traffic management strategies, ensuring that road systems remain efficient and safe for all road users.
Road Tubes: Beyond Just Counting
While the primary function of these pneumatic road tubes is traffic counting, their utility extends far beyond mere enumeration.3 These inconspicuous instruments serve as multi-dimensional data collectors, playing a pivotal role in enhancing our road infrastructure and ensuring smooth traffic flow.
The U.S. Department of Transportation sheds light on the operational intricacies of these tubes. When a vehicle’s tires traverse the rubber tube, a burst of air pressure is generated, closing an air switch that sends an electrical signal to a counter device. These tubes can be set up either as temporary or permanent installations, each serving distinct purposes. Temporary configurations, often lasting only a day, offer quick glimpses into traffic dynamics, while permanent setups provide continuous, in-depth monitoring.
Transportation agencies strategically position these black cables in areas with minimal interference, targeting straight stretches of road for optimal data collection. Through single-tube setups, agencies can gauge vehicle counts and time gaps between vehicles. When utilizing paired tubes, the system delves into the intricacies of traffic, capturing axle count, direction, and speed.
These unassuming tubes also step in when urban road management faces challenges. If residents raise concerns about speeding or shortcutting, these tubes are deployed to investigate and validate claims. The data they generate contributes to the formulation of transportation budgets and the implementation of effective solutions.
In conclusion, the next time you encounter those mysterious black cables stretching across the road, you can appreciate the intricate web of data they weave behind the scenes. These unassuming instruments serve as silent observers, capturing the heartbeat of our roads and guiding the decisions that shape our transportation landscape. As you pass over these tubes, remember that they are more than meets the eye— they are the pulse of our evolving road networks.
