Experienced tutor in Mathematics in Arvada, Anna offers private lessons tailored to your needs.

Very happy with our experience, my son's timeline was very limited and he needed to improve his Math ACT by 1 or 2 points. Mr. Chacon found the perfect match for him with Dom, she was incredibly smart and explained it exactly how my son needed it. His score improved by 4 points!!

he was a good tutor not so much as i got to use him but he treated me with kindness and respect i never got to use him i did not but if i could i would give him a 10,000

My daughter has always struggled with math. The tutors with Flatirons made a big difference. She ended up with an A in geometry! They made the process very easy by coming to our home and determining the day and time as she needed help.

Mr. Chacon has been a very influential teacher in my life. I initially had him in 9th grade for algebra I and then in 11th grade for physics II. Throughout high school, he tutored me in math, science and SAT prep. By the time it came time to write my senior thesis, I approached Mr. Chacon to ask if he'd be my advisor. Fortunately, he agreed to work with me. My senior thesis ended up being selected as one of the top three. I am extremely grateful for all the support Mr. Chacon has provided me throughout high school.

Cris did an awesome job with helping my with physics and math, gives great feedback and helps any way he can.

Flatirons tutoring was super helpful, I learned a lot more than just what the classes taught me and I would definitely recommend to anyone in need of some extra help. On top of that my tutors have been very knowledgeable and professional at what they do

I think this tutoring helped me in the summer to be prepared for whatever subject I was working on also helping me in the school year knowing what to do for that subject.

Flatirons Tutoring is an asset to our community and we would highly recommend using this service for SAT/ACT prep or any specific subject support. Our high school senior worked with Cris in math, reading, and science to bolster his current course performance and prepare for college entrance exams. We saw growth in our son's confidence, ability, and scores which enabled him to be competitive when applying for scholarships and colleges. Although first reluctant to spend the money and time on a tutoring service, we are grateful to have found Cris and realize it was well worth the investment!

We had a great experience with this program and would highly recommend!! My son was coming off a rough year of high school due to Covid restrictions and really regressed on his math. He was in Honors math and struggling mightily. Cris worked with him on a weekly basis and built his foundational knowledge back up to the point where he's in AP Calculus in this final year of HS and averaging over a 95 with a 100 on a couple of tests! I credit this Cris' program with understanding how my son thinks and works and setting up a study plan that catered to his strengths.

We have had a great experience working with Chris and Amy. They have worked with our daughter as needed over the last 2 years. Our daughter doesn’t like to ask for help if she doesn’t understand concepts but she never gets intimidating working with them. Thanks for the consistent and professional service and always understanding you are working with kids.

Cris has done a fabulous job of tutoring Algebra 2 to my daughter. It is her least confident subject and Cris has done a great job teaching her the concepts in a way that my daughter can easily understand. She really enjoys working with him.

Cris has helped my kids with math and AP physics. He is such a wonderful teacher!! His knowledge and way of teaching have been extremely valuable. Many thanks to him and will continue using him as long as needed.

Cris Chacon has provided invaluable support to our daughter over the past 4 years. We adopted our daughter from Nepal in 2019. She was 13 years old and spoke very little English. There were large gaps in her understanding of basic mathematical concepts. She especially struggled with word problems. Fortunately, she had Cris as her 9th grade Algebra I teacher. He helped her tremendously that year. We started private tutoring lessons and SAT preparation with him the following year. Cris has really helped our daughter to fill in the gaps in her previous education and to gain more confidence in math.

Cris is professional, very responsive to our needs and adjustments to scheduling very quickly. My students excelled and improved study habits for other courses. Highly recommend Chris.

We have been thrilled with Flatirons Tutoring. Our match with our tutor SJ could not have been more perfect. The approach SJ has with both of our children who have learning disabilities is incredible. SJ is able to refocus the children when they get off track or frustrated and always brings new learning strategies to the table. We can not recommend Flatirons tutoring more!!!!

Cris was a great find for my son who was a Junior in High School! He struggled with Algebra II all year and honestly if it wasn't for Cris he would have failed. My son has expressed several times how much better Cris is at explaining the problems then his own teachers, he was able to learn a different way then what was being taught in class. Cris is super professional, has flexibility with schedules and very responsive when we were in a bind to crunch for finals or an exam. If you are currently looking for a tutor for your child, you need to look no further!

Cris worked with my son in mathematics catching him up before his Freshman year. My son had missed nearly a year and a half of direct instruction, and with Cris's tutoring support he received straight A's in math this year!

Cris worked with my 9th grader (Algebra 1) from Spring Break through final exams this year - it made a huge impact. He explained how to work out problems that she had been struggling with in a way she clearly understood. She improved her grade immensely, but even more importantly, she has regained confidence. We will not hesitate to work with Cris again - thank you!

Cris did a great job helping my child understand Algebra II this year. Highly recommend!

He really helped with preparing for advanced placement calculus. The online meetings with screen sharing were a big time saver.

Cris has tutored both of my daughters on various level of math, ranging from Algebra 1 to IB Physics. My daughters love how he explains concepts using his iPad and visually demonstrates how to solve the problem. He has been very flexible with timing, especially if we have a last minute request.

I highly recommend Flatirons Tutoring for any high schooler that is looking for some help in complex subjects! Cris was such a help for our daughter that was struggling with Physics. Cris has a gift of not only working with high school kids but also for breaking down complex topics into manageable pieces!

Before Flatirons Tutoring, my SAT score was very low; Then, when I started tutoring sessions with Flatirons, I started to understand what I needed to work on and ways improve on that specific area, with the help of Cris. I was able to raise my score by 200+ points. I would definitely recommend; Cris was easy to work with, flexible, and was definitely very helpful.

After taking a couple practice SAT’s, I was doing pretty well but wanted to improve my score. Khan Academy was pretty useful but didn’t help with tactics for taking the test. Because of this, I went to Flatirons tutoring and really enjoyed the tutoring. I learned the test much better, incorporated what I learned into my practice, and improved my score by 80 points in only a couple weeks. Definitely recommend, at least a try!

I have been out of school for a bit and not taken math for even longer but am learning how to program for a new job. I am jumping into calculus at a college level and was extremely nervous. Working with Cris (remotely) was beyond helpful. He helped me brush up on basics in algebra, trigonometry and pre calc in one session. Feeling much more confident and ready to jump back in. I will be reaching out again next time I need help! Thanks Cris

COVID and online learning created a bit of a challenge for our son. He had always been a straight A Honors student and wanted to continue with those goals despite the challenges of COVID. Cris came highly recommended after some unsuccessful trials with other tutors. Cris took the time to get to know our son both on a personal and educational level—which created a great fit! His personal connection with our son, helped open the door for more learning and advancement. Our son’s goal was met and we will continue to use Cris and Flatirons tutoring in the future.

I just finished up my senior year of high school, and this semester I was enrolled in a college level calc class. Right away, I found that this class was very challenging and I was in need of some help if I wanted to maintain my GPA. That's when I reached out to Cris. Right away, he was super nice and offered to call to talk about what I was struggling with and how he thought he could help and I was very impressed! He was extremely flexible with when we could set up times to meet which was great because my schedule could get very busy with school events and other things. He helped me work through problems that I didn't understand, and then had me repeat back the steps we took to get to the answer so that I was able to remember everything by putting it in my own terms. Overall, super friendly and great experience. I was nervous about my grade dropping before tutoring but glad I reached out because I ended the class with a high A!

We appreciated that Mr Chacon tailored the tutoring session to what our son needed to prepare for the SAT. He spent time going over previous practice tests and gave good insight into how to better approach some of the questions and how to best use his test time. Our son was able to increase his overall score by 90 points.

My son had been trying to get ahead of his current math class, so we first decided on Chris because he was my son's previous physics teacher. When my son came back from his first lesson, I could tell that it was a good choice because he already had a clear understanding of the start of his course. My son eventually came to pass his course easily with Chris' help, and was well prepared for his next math class. Chris was clear in communicating, had a decent understanding of my son's goals and course desires, and most of all held my son's priorities above his own.

Cris Chacon at Flatirons Tutoring helped my daughter, Emily, with math in high school. Emily felt very overwhelmed and confused. Chris tutored her weekly. He was able not only to build her self-confidence, but to explain word problems and equations so that she could understand them and do the work on her own. Cris is incredibly knowledgeable, kind and professional. He is easy to communicate with and always prompt and efficient. I would highly recommend his services to anyone challenged academically.

Our son was struggling with Math. Mr Chacon was his teacher and already showed a high level of engagement and desire to see our son succeed. We were excited to know he would be willing and able to tutor our son. Our son connected with Mr Chacon on various levels but his desire to see our son do well was the single greatest motivator for our son to continue and enjoy his time. The one on one help really made a difference due to the specific help he needed vs the general teaching that goes on in a classroom which is understandable. There is a door to success that needs to be walked through by parents and also the student which can be daunting but we would highly recommend it. Tutoring and especially with Mr Chacon will help but only if engaged in. I couldn't recommend Mr Chacon more!

Knowledgeable, professional

Cris is very helpful and smart. He helped me get through math and science when I needed help. He makes sure to ask questions so that I explain my thinking and gives the right feedback to help me learn how to solve problems myself without doing it for me, but can also teach me concepts I don’t yet know.
