Brain exercises to keep you sharp

Around this time, school SOLs, SATs, and final exams are progressing along.  And as my kids still learn new information in class, they are still responsible for the end of the year comprehensive tests, which means, everything they have learned at the beginning of the year to current will make it on the exam.  The problem with that is when information is stored for quite a bit, it tends to be forgotten. Luckily, there is a free non-profit website that helps with reviewing those old, and recent, topics discussed in class.  The only catch is, you have to put the time and effort to use it.  The website is called KhanAcademy. Below you will see why this website is an amazing resource to have at your fingertips.  It has definitely proven to be of great use to us.

I originally found this website because I was looking for information to help one of my kids with pre-Algebra.  While I have taken it in middle school in the 80s (Wow, I feel so old saying that!), I don’t remember quite as much about it, and in definite need of a refresher in order to help.  A simple online search brought Khan Academy to my attention.  I created a free account for my child; but, what I did not know is that I can also create an account for me, separate from my kid’s progress. So, I created one for myself as well; and though not regularly, I stop by once in a while to improve my brain cells too.  I’m all for improving oneself, which is why I love to read.

For me, Grammar is of special interest.  You may have already figured it out from my post(s) that I am not the greatest in using commas.  However, I am taking steps to improve it, and that’s what matters.   This summer, I’m definitely going to use the Algebra portion of this website to help my kid progress on to Algebra next school year. Maybe I’ll squeeze in some SAT review as well.  I believe my teen is eligible next school year.  College will be here for us before we know it.  Preparation is key for admission acceptance.

While an account is not necessary, having an account allows for the progression to be saved, which I think is a plus. I can save up to 9 subjects on my page at a time, for easier access to information, with options to change it whenever I want.

KhanAcademy offers video tutorials, quizzes and tests to weigh-in the progress.  The video tutorials also come with transcripts below, for those that prefer to read along with the video or prefer to just read the information.  Questions can be posted on each tutorial as well for further clarification on the subject matter.

I also get badges for completed goals, which is bascially an online version of a teacher’s gold sticker.  haha.
