Why MathPlus?

Sending our son to MathPlus is one of the best decisions we’ve made.  MathPlus is able to provide a unique program to meet my son’s specific needs in Math as a high school student.  Just after a couple months of attending MathPlus, my son already shows more interest in Math. A few months later, he started to show improvements and confidence in math. We really appreciate MathPlus for providing a positive and encouraging learning experience for my son.

- Sarah K.

We are very happy that this program exists. Our children have gained not only more knowledge but also became very confident in their math skills. They truly enjoy the class, where the teachers are explaining the concepts in a very detailed manner, with lots of patience. The teaching assistants are very nice and helpful. The assigned homework is based on the concepts taught in the MathPlus class and these concepts are reinforced at the top of every homework page. In their school, the children’s teachers are very pleased with the children A+ level progress in math and started to recommend the MathPlus program to other parents.

MathPlus Staff

Dedicated to educating and helping our youth achieving their best.

…The tutors are well-versed in mathematics and are also extremely patient. We heartily recommend MathPlus to any math student who would like to achieve at the highest levels.

- Dawn and Bryan A.

The TAs would always be patient and help me solve it step by step so I could do future problems or even different variations of it without any help. Back in 6th grade I skipped pre-algebra and moved to Algebra so harder math questions have always been easier than simple ones like percentages. MathPlus helped build my fundamentals back up which probably helped further down the line of my academics without me realizing so.

As parents of two daughters who have built a love for Math through this program, we can’t recommend MathPlus enough. MathPlus is more than just a math enrichment program. It is a community of passionate educators from the owners Kai and Yihfen, to the TAs on their staff but also the curious learners and supportive peers who share a common goal: to explore the beauty and power of mathematics.

Our daughters have been attending MathPlus for over 8 years now, and we have seen them grow not only in their math skills, but also in their confidence, creativity and critical thinking. They enjoy the engaging and challenging lessons that cover topics beyond the school curriculum, such as logic puzzles, number theory, geometry and algebra in the form of both typical problems and complex multi step word problems. They also appreciate the individualized feedback and guidance they receive from their teaching assistants, who are always friendly, patient and knowledgeable.  Many of the TAs have been through the program themselves so they have and share firsthand knowledge of how the program works and how to maximize the learning model.

MathPlus has helped our daughters develop a deeper appreciation and understanding of math, and has inspired them to pursue their interests and goals in STEM fields. They look forward to every session and always come home with a smile on their face and a new math skill to share with us. We are so grateful to MathPlus for providing such a wonderful learning opportunity for our daughters. Thank you, MathPlus!

- Michael and Rikki W.

(My son) will be a freshman this year on a full scholarship for 4 years in no small part due to what you have taught him over the last several years. He chose not to do boarding school and instead opted to stay home even though he scored in the 99% on the ssat again due to you. We cannot thank you both enough for everything you have done for him! The ROI on Mathplus has definitely worked in our favor! Thank you so very much!!

– Dawn and Bryan A.

The Mathplus program is the best to help my kids build up their solid foundation and confidence, in not only their math skills but also other courses, like STEM. Their outstanding school performances are the results of their effort in the Mathplus program. I am really impressed by the strategies Mathplus has designed to help my kids go through every level successfully. The sample pages show how to solve the problems step-by-step, so that my kids could complete their worksheets independently by following the instructions, which also nurtures their self-learning abilities naturally. The homework assignment is focused and relevant to help them practice and enhance what they learnt in class. Weekly quiz and achievement test demonstrate to which concept they need to work harder. The TAs are dedicated to teaching my kids with great patience. I am also very appreciative to the prompt communication from Mathplus anytime I have questions. Thumbs up and thank you Mathplus!

- Meihua X.

I know this is sappy but honestly, my kids would be nothing without you. …. so from the bottom of my heart “thank you.”

- Tracy M.

I first started here 2 years ago. My math skills were terrible and my math grade was just ok. Once I started MathPlus, my math grades were all high and I qualified to jump a math level at school.

- Jerry Y. (previous student)

That’s a great report and I appreciate your support.  It’s exciting to see his progress and I can’t tell you enough how much your program means to the enrichment of our children!

- Kelly Z.

You have helped both my kids do well in school, and for that, I will always be grateful. (My son) particularly has developed a love of Math and wants to spend Saturday mornings at the center instead of skiing or doing something else.

- Anuraag S.

(My daughter) is in her current math level – credit to MathPlus. We will forever be grateful to the program. The program is a gem in DE, with high expectations, and runs sincerely.

- Sheela S.

(My daughter) is doing great, and her math skill definitely has gotten much more solid through the MathPlus program, she is ready to take on AP Calc this coming year. We really appreciate MathPlus has provided her the great tools.

- Christy O.

We have had two boys go through the MathPlus program and have been delighted with the results. Both boys were strong math students to begin with, but the program helped increase their focus, speed and accuracy for doing much more advanced math problems. Our older son was able to complete all the math courses (including three advanced placement math classes) offered at his high school. Our younger son, who is still in the program, appears to be on a similar track. We believe that the MathPlus program also increased their confidence that they could successfully solve problems in a very timely fashion. We would highly recommend the program for kids of all levels. You will see your kids become more confident math students who really enjoy solving math problems.
