Testimonials

It's harder to work through the problem than being given the answer. But when I was looking at my required college curriculum, I realized that this work helped me prepare better for college. You understand the methods for solving the problem, instead of a teacher handing you the formula. You understand why it works that way.

Senior, (4th year of CPM)

We are already seeing the benefits of the program (after 3 years). Students seem to be better prepared for higher level math courses and stronger results are showing up on various standardized tests.

Peter, Director of Curriculum and Instruction

My daughter has always struggled with mathematics. But with CPM she began to like math and really understands what she is learning. All of the hands-on learning tools, like the Algebra tiles, have really helped her to finally succeed in math class.

Parent of CPM Student

One of the main things I've heard from the teachers is that the structure of the lessons gives them the ability to quickly identify how individuals, small groups and the entire class are doing during a lesson. As a result the teachers are able to interact with students or facilitate activities to provide immediate responses. Students are less likely to fall through the cracks and students continue to progress at a productive pace.

Travis, Math Coordinator

Students are organized into study teams and work on problem-based applications, team strategies and real-world applications. Many algebra teachers feel reenergized and are having more fun teaching math with the CPM approach. Algebra classes focus on both basic skills and problem solving strategies that are used to help students relate to and understand the concepts behind the problems. Our students are being taught Algebra in a more rigorous and relevant manner. It's really about discovering the math, rather than being told the math.

24/7 Homework Help: Get Help Online

The downsides of getting free homework help.

When we aren’t able to deal with the pile of hometasks ourselves, we think about getting any help. If our parents had to ask their parents or other seniors for help, then we have a wonderful opportunity to check, for example, Chegg: homework help of any kind can be found there. Also there are dozens of other platforms that offer homework help of different types. For example, we all love to scroll through Reddit threads sometimes. However, apart from gossiping and meaningless talks, there might be something important and serious there as well.

Reddit homework help is also quite popular, as most tasks in schools and colleges are taken from the same books. But have your ever thought that free homework help might be dangerous for you? First of all, it’s a wrong answer to the task. Just imagine that you copy something without thinking, and bring it to class. Oops, apparently, the answer is wrong, but you can’t even explain how you were working on this task, because you wasn’t…

One of the most tricky aspects here is math homework help. Sometimes, the right answer is not enough. A student should follow a certain algorithm when solving the task. And professional services will help him with that. No need to worry about any type math: algebra homework help, geometry and other subjects are available.

As a result, you will save your time, avoid mistakes and errors, pay a reasonable price and, mot importantly, will be confident in the correct answer. How all these became possible?

Advantages of modern technologies

We are very lucky to live in the data-driven era, when anything we want is available with one click of the mouse (in fact, you don’t even need a mouse). College homework help is available online at any time you need it. Forget about time zones, don’t think about living in a small town, when the power of the whole world is in front of you! Get help with tasks of any complexity, regardless of the subject. Not need to be a pro in accounting: homework help will change the way you think about studies!

Choose you subject and get the best homework help: math, physics, biology, chemistry, literature, etc.

Homework help

The downsides of free homework help..

How often do use assistance of the Internet in doing your homework? We bet, it's your daily routine to open a browser and start looking for solutions. Do you think the strangers on the other side of the screen will provide necessary information for your math homework help? Unlikely! After one successful task there might be a sad outcome. We want you to be cautious about the websites you look for assistance, that's why we have gathered the disadvantages of asking Google for free homework help.

First, and the main downside is the inability to check the result. People helping you with your task might not know the answers themselves. And what assistance would you get in this case? Wrong answers!

Second, it's the proficiency of the strangers on the other side of the screen. Who are they? College professors who came to provide homework help for free? Or just students like you who might not be able to cope with a simple task. They might not now anything about the subject, or might be way too self-confident and give you wrong answers.

Think twice before using the help from these people. In the next part of the article we describe the most popular sources of homework assistance and give our honest opinion about them.

The best websites for homework help.

When a student is looking for help he always (no exaggeration!) expects it to be free. Of course, being a college student always means being tight on budget and looking for the ways to save money even more. But it should be related to college homework help. Sadly, there are thousands of examples when a bad homework resulted in bad grades, and a poor student had to learn more to pass the exam. That's why we don't recommend to look for answers on the websites like Reddit or Chegg. Why? We explain below.

Chegg homework help is a paid service. You need to buy a monthly subscription to use it. Is it worth it? Depends on your professor. If the tasks you get are strictly from a textbook, then it might be good. To cope with a creative teachers this website has nothing to offer.

The same goes for Reddit homework help. It might be useful when you're looking for solutions on a standard task, the one that dozens of people are struggling with as well. There's nothing these services can offer if you're homework is unique and created by a teacher himself. What to do in this case? Read our recommendations below.

We recommend to try it!

There's an easy and cheap solution that will help you succeed in your studies. A personal assistance with homework created just for your tasks. No need to scroll pages looking for similar tasks and subjects, no need to copy from the screen and guess, if the results are correct. Professionals will perform the task for you! All you have to do is to provide it and enjoy a personalized approach and high quality service. After that you'll never come back to Reddit in search of answers!
