    We had a very positive experience with Alissa as a tutor for our pod of 5th grade boys from January - June 2020. She cared a lot about the boys and worked hard to create meaningful activities for them. The pod experience was invaluable … More for all of our families during a difficult year and we were so grateful to have found this partnership! We also want to appreciate Craig for helping to match us with a tutor on very short notice after we had cycled through a few folks who were not able to see the commitment through. Thanks for sticking with us!

We are also thankful that Craig at Themba Tutors really "gets it" and partnered us with such a wonderful tutor who was a great fit for our girl.
  • Avatar Nicole May ★★★★★ 3 years ago

    Our son started in a new high school, 100% remote, and was really struggling with Latin and Physics. I found Themba Tudors online and had an initial call with Craig, who was very knowledgeable, responsive, and found 2 amazing tutors for … More us. Both the Latin and the physics tutors were fantastic, connected with my son really well and helped him go from 'failing' grade to 'honors'! I will for sure continue using (and recommending!) Themba Tutors. Thank you, C, K, and W!

  • Avatar Christine Gennetti ★★★★★ 3 years ago
    As an adult student diagnosed with a learning disability during grad school, I knew I needed help dealing with my Master's program's demanding workload. I was seriously considering dropping out when I was referred to Themba Tutors. … More I was paired up with a wonderful tutor, Julie, who was a total lifesaver. I learned many techniques that I can utilize in the future as I embark on the next phase of my career.
    I can wholeheartedly say after working with Themba for two years that I would not have finished my program without this organization. And I am so thankful I selected them.

    We were introduced to a wonderful tutor: Mcedwyn. He and our son, a freshman in college, worked well together. As a result, our son’s grades significantly improved. The tutor taught our son subject content and various methods to effectively … More study for quizzes and exams. Our son was also taught time management and organization. My son’s experience with the tutor made the first year of college a less intimidating experience.
  • Avatar Jude Eugene ★★★★★ 3 years ago
    We have been with our tutor, Cailin Schiller, for two years, from 5th - 7th grade. She started as an executive functioning tutor with my daughter. From the start, she demonstrated a depth of expertise and a selective use of techniques skillfully … More adapted to my daughter’s ADHD and Math disability. Cailin made Math accessible and understandable to her in a way that even her teachers had not been able to do. She differentiated reading, writing and math tasks and assignments to tailor them to my daughter’s unique learning differences. Not only did it have an effect on her grades and her work efficiency, but she finally could do her work with less anxiety. Even my daughter’s teachers used Cailin’s guidance to modify their work with her. But most importantly, she became my daughter’s favorite resource. I can’t say how invaluable Cailin has been to my daughter’s progress and well-being. I’d recommend her a million times over. She is a gem.

    Themba Tutors provided a leaning specialist that was a perfect fit for my daughter. I told them what we were looking for and they delivered. Our tutor is responsive and flexible and makes it easy for my daughter to reach out to her own … More her own, which gives her an added sense of responsibility over her learning. As a therapist myself, I now regularly recommend Themba to my patients. A much needed and well provided service to the community!!

    The tutors at Themba are fantastic! Caitlyn McNeill helped our son academically, but also with getting organized in every subject, which he so desperately needed.

    Paul Smith at Themba has been an exceptional tutor for my son, both in terms of teaching the subject matter and teaching how best to approach the process of learning math and executing assignments. We feel very fortunate to be working with … More Paul.
  • Avatar Monica Alzate ★★★★★ 5 years ago
    We were very lucky to have found Edwouine Swift, my son's therapist through Themba Tutors. Thomas is 12 years old, and it is extremely difficult to get him to write. Edwouine just works her magic with him, he adores her and is so … More eager to follow her guidance. I have no doubt she will be a positive driving force in his academic future.

📚 DELTAMATH TUTORING IN NYC: BOOST MATH CONFIDENCE WITH SUPPORT FROM THEMBA TUTORS

deltamath

Is your child feeling frustrated or anxious when working through DeltaMath assignments? Are they confused by the online platform and falling behind in math class? Whether you live in Manhattan, Brooklyn, Queens, the Bronx, Staten Island, or even in the surrounding suburbs, Themba Tutors is here to help. Our math tutors for K-12 students specialize in decoding the platform’s tools, boosting understanding, and improving math performance for all students, including neurodiverse and twice-exceptional learners.

At Themba Tutors, we understand that DeltaMath can be intimidating—especially for families unfamiliar with its setup. That’s why our expert tutors offer customized support to help your child thrive, one problem at a time.

📚 What Is DeltaMath? | A Guide for Students and Educators

DeltaMath is an interactive, digital math platform used by thousands of middle and high schools across NYC and the country. It allows students to complete math assignments, receive automatic grading, and get real-time feedback from teachers. With more than 1,800 problem types spanning Algebra 1, Geometry, Trigonometry, Algebra 2, Precalculus, Calculus, and even Statistics, DeltaMath is a powerful online classroom and RTI program in one.

 

Built with both student and teacher functionality, DeltaMath allows educators to track growth, customize lessons, and reduce cheating through clever anti-copy tools. Many NYC schools integrate it with systems like Google Classroom or Schoology for seamless instruction.

📌 When Do Parents Need a DeltaMath Tutor? | Assignments & Academic Struggles

If your child is struggling to complete DeltaMath assignments independently, missing deadlines, or receiving low scores, it may be time for professional help. Our DeltaMath tutors are trained to identify learning gaps, explain concepts clearly, and build confidence around topics that often feel frustrating. Many parents come to us with concerns like:

  • “My child keeps getting the same problems wrong.”
  • “They don’t understand why they lost points.”
  • “They’re spending hours on DeltaMath and getting nowhere.”

 

We help with more than homework—we provide consistent support for questions your child might be too embarrassed to ask in class. Whether they’re preparing for Regents, SAT, or ACT exams, or just trying to pass the quarter, our tutors bring calm, structure, and results to every session.

 

Common Google searches we see:

  • “DeltaMath tutor Brooklyn”
  • “Help with DeltaMath homework NYC”
  • “Algebra tutor who knows DeltaMath”
  • “Struggling with DeltaMath assignments in Queens”

Can We Use DeltaMath Without a School Account?

deltamath

Absolutely! Even if your child’s school doesn’t officially assign work via DeltaMath, it’s still a fantastic tool for practice and review. We create a custom account for your child and use DeltaMath to reinforce what they’re learning in class—or to address topics where they’re behind.

 

DeltaMath is especially helpful during:

  • Summer break (to avoid the “summer slide”)
  • Long school absences due to illness or travel
  • Homeschooling or supplemental learning outside the classroom

 

We also assist parents and educators in reviewing school information, understanding standards, and aligning DeltaMath lessons to IEP or 504 goals. Our goal is to make sure every child receives a clear, personalized path forward.

💻 Free vs Paid DeltaMath Accounts | What’s Best for Your Student?

There are two main DeltaMath account types, and our tutors are familiar with both:

Free DeltaMath Teacher Account:

  • Unlimited access to 1,800+ problem types
  • Create and assign personalized assignments
  • Automatic grading with timestamps
  • Copy and share problems with ease
  • Cheat-prevention settings
  • Google sign-in integration
  • View individual and group progress

 

DeltaMath PLUS ($95/year):

  • Watch instructional videos for each topic
  • Assign videos from YouTube for context
  • Create custom tests and quizzes
  • Target specific skills and standards
  • Add co-teachers and organize folders
  • Use the admin dashboard to analyze student data

 

Whether your child is using a school-provided account or one we’ve created, our tutoring can be adapted to maximize results.

✏️ How Our Tutors Use DeltaMath in Lessons | Customization and Edits

At Themba Tutors, we go far beyond just walking your child through math problems. Our tutors personalize DeltaMath by editing problem sets, layering in visuals and explanations, and pacing work based on your child’s attention span and stamina. Our lessons are aligned with NYS math standards, Regents prep, and Common Core expectations.

Benefits of our DeltaMath tutoring:

  • Real-time, supportive question review
  • Skill tracking to identify weak areas
  • Interactive modeling of problems
  • Use of visual aids and relatable analogies
  • Incorporation of neurodiverse learning strategies

And since many of our tutors are also certified teachers, they understand how to connect DeltaMath work with classroom assignments, tests, and broader academic expectations.

🛠️ DeltaMath Help Center and Email Support | Troubleshooting Your Account

deltamath

Technology should help—not hinder—your child’s education. If your student is having trouble with their DeltaMath account, forgot a password, or can’t load their class assignments, we’re here to help. We assist families in using the DeltaMath Help Center, which includes FAQs, instructional guides, and contact forms.

 

Additionally, we can:

  • Walk your child through login issues
  • Help you reset account credentials
  • Send direct emails to teachers when needed
    Organize a streamlined system for tracking due dates

Many families say our support is just as valuable for tech as it is for math!
