Tutoring Discounts due to Amazon Disruption

Half Price on Tutoring

Unfortunately for authors and publishers (including myself), Amazon has made some major changes which are going to significantly hurt our revenue stream, thus making it very difficult for us to continue to fund new projects. Therefore, I am going to have to stop dedicating my time to writing new books.

The good news is that this is going to allow me to dedicate more time to working with students. Since I will be able to run more classes and take on more students, I am temporarily going to be offering a significant discount. When you send me an email with the code "Get800BlogDiscount" in the subject line, you will qualify for tutoring at half of my usual rate. So, I will...


Solving Linear Equations - Unicorn Puzzle Activity


This one is for the math teachers. Sticking with the unicorn theme, I just made a math activity for those of you teaching algebra.

This activity consists of 5 levels of problems all involving solving linear equations. Each level consists of 9 problems. Each problem comes with a puzzle piece, and the solution to the problem tells you where to place the piece. I prefer to have the students simply draw the piece in the appropriate place in the answer grid, but you can also have them paste the piece in. The final result is a unicorn head, as displayed on the cover above.

Problems start out with very simple equations and proceed to more difficult word problems that are consistent with the types of...

Today I would like to give you a difficult Heart of Algebra problem with a solution. Additional methods of solution will be provided in the next few days.

Level 5 Heart of Algebra

A worker earns $12 per hour for the first 40 hours he works in any given week, and $18 per hour for each hour above 40 that he works each week. If the worker saves 75% of his earnings each week, what is the least number of hours he must work in a week to save at least $441 for the week?

Improve Your Math Score by Teaching Math to Others

Improve Your Math Score by Teaching Math to Others

This week I would like to share an approach to improving your own math score on standardized tests such as the SAT and ACT by helping other students to improve their score. Every student I tutor is encouraged to pass along their knowledge to other students as there are many benefits for both students.

I believe that if you want to take yourself to the next level without too much effort, simply teach what you already know to someone else. Helping someone else to learn something new requires a much deeper understanding of the underlying material than simply having superficial knowledge of the subject matter. By engaging with someone else with ...
