linear programming

TGIF! To finish off the week I’ve worked through a dreaded linear programming word problem. Depending on your Algebra class, you might not have to write the inequalities yourself…which would make it MUCH easier! Just in case some of you have to do this type of problem from scratch however, I’ve shown you how I typically organize the numbers in a chart. I’ve found this makes the whole process a lot easier :)


I also gave out my very first #mathsaverfavor this week! It was a Statistics question from a college Statistics student which involved comparing the difference between two means by running a hypothesis test and creating a confidence interval. I didn’t make a video for it, but I’ve included the notes that I wrote out and sent to that student earlier this week! I don’t regularly post on my blog regarding Statistics questions, but I do tutor several AP Statistics students each week so those types of questions are always welcome here!!


Here’s the original question:



And here is my worked out solution:

happy friday

I don’t know why, but this has felt like the LONGEST week! Whew…at least it’s Friday!


My Algebra students are working on solving systems of equations so I thought it would be helpful to pick one problem and show how solving it by graphing, by substitution and by elimination will get you to the same exact answer!


I hope you have a great weekend! See you next week :)

word problems don’t have to be confusing!

Happy Friday everyone! I haven’t had any takers yet on my Friday idea of #mathsaverfavor, but I’m keeping the offer open every week. Any math questions that you might have during the week just send them my way, and I’ll publish a video tutorial on Friday of that week!


My Algebra students have recently been putting their new knowledge of linear equations y=mx+b and y-y1 = m(x-x1) to the test by using them in word problems. If you can pick out the key pieces of what a word problem is asking, they honestly won’t be confusing! I’ve explained two of the main types of word problems that you will come across in Algebra when you’re working with linear equations…



I hope you all have a great weekend and Thanksgiving! I will be taking next week off for Thanksgiving so I probably won’t be recording any videos, but I might still be able to write a few helpful posts. And if anyone sends me a question I will for sure find a way to record and publish a video answer for next Friday!!

math favor friday

So why did I title this “Math Favor Friday”?? Well, I’d like to reserve Fridays not only for Algebra 1, but also to answer one of YOUR math questions that you might have had in class during the week! I didn’t have any takers for this Friday, but I’m going to keep the offer open. So if you come across my blog and don’t see your specific question in any of my current videos…just leave me a comment, send me an email, or find me on one of my social accounts (those buttons at the very top of my page and let’s use #mathsaverfavor) and ask away! If I get too many requests I will pick the most-asked question for that week…otherwise I will answer everyone’s questions each Friday!!


For Algebra 1 this week, a lot of my students are learning how to write the equation of a line using slope-intercept form and point-slope form. They always have the most trouble when asked to write the equation of a line that’s parallel or perpendicular to another line…especially if it’s a vertical or horizontal line! Watch the following video to see a few examples of how to do this without making any of the common mistakes.



Have a great weekend, and I’ll see you next week!

Algebra Friday!

I can’t think of a better way to finish off the week than with a little Algebra! Most of my Algebra students are 7th and 8th graders, but kids who are even younger than that will start to see glimpses of Algebra in elementary school. The videos that I create for Algebra will follow the path and pace of students who will be moving on to a full year of Geometry next year, but I’m sure some of you younger kids will find the videos helpful too! Algebra shows up everywhere…it’s SO important. You will keep using it throughout all of your years of high school so you want to become amazing at it NOW :)


This past week my students were solving equations that had x on both sides. Just tell yourself these 3 steps: distribute, combine like terms, get x alone. In that order. For most beginning equations, if you follow this pattern you will solve for that pesky x in no time! Here are a few examples…



This has been a great first week, and I’m looking forward to many more! We will be back to conquering Calculus on Monday, but until then have a wonderful weekend!!
