# The Humble Calculator (Triad Math review)

Disclosure: I received this complimentary product through the Homeschool Review Crew.

I grew up using a Texas Instruments scientific calculator, and I’d be willing to bet many of you did as well. What I bet most of us don’t know, however, is the sheer amount of power that humble machine has. Enter Mastering the TI-30Xa Scientific Calculator: Augmented Intelligence for all 21st Century Students from Triad Math, Inc. In this course, which is a combination of video lessons, a work text with problems to solve, and the calculator itself, students learn all about the nuances and extraordinary power this calculator has.

When we first got access to the course, I gave the book to Ballet Boy (17) and emailed him the login credentials for the video lessons. Then, he worked on the course independently each day. From my perspective, the course was very easy to navigate. When we logged in, it was easy to find the right course, and then to scroll down through the lessons. The interface kept track of where you left off, so it was a breeze to move to the next lesson correctly. I did the first few lessons with my son, and I found the teaching to be very clear and easy to follow. The questions in the textbook went well with the lessons.

Each lesson consists of a pretest, the video lesson, practice questions (available as PDFs within the course or as a separate book, as we received), and a post-test. The post-test is identical to the pretest, except it’s taken after the lesson to make sure the student has learned the material. Each lesson also has a forum, but we didn’t utilize those.

Here are Ballet Boy’s thoughts.

I’ve been using the Texas Instruments calculator for a few weeks now and let me just say: this calculator is AMAZING! It’s the only calculator I’ve used that was actually useful for math. All calculators do math, of course, but I’m not in third grade so one that does more that multiply and divide is a welcome sight. I have yet to come across an equation or geometry problem that isn’t made easy with this tool. The calculator even does trigonometry with a few clicks of a button. It also has three memory banks for doing complex word problems. I have done entire math lessons without even scratch paper.

Additionally, the course has many video lessons and a work book that go with it to help you understand every button one step at a time. The videos are super easy to understand and follow along with. What I will say is when you’re watching them, “Dr. Del” is a lesson behind when he tells you what lesson number you’re on so that’s confusing at first, but only a small bug.

All in all I have no problems with the class, only praise. Highly recommended!!
