6th grader, “Kermit”, shows us 3 interesting ways to remember the 9’s – – multiplication by 9.

She recorded and edited the entire screencast by herself!

Part of the student-created Mathtrain.TV project.

“Paul” returns from high school to do a basic trig video. She shows us the famous “soh cah toa” used in trigonometry.

An algebra student had this question for homework.  This is a tutorial for a completing the square problem from Mathtrain.TV.

A visual look at subtracting fractions.  This goes along with another video we made several years ago. Here, we use pizza as a way to help visual this subtraction of fractions.

Original video with alternative method is at http://youtu.be/yXiG2iv1Vq8 .

7th grader, “Rebecca”, introduces us to fraction busters – a way to simplify solving equations.

7th Grader, “Betty”, debuts with her tutorial. She takes the word problem, translates it into algebra, and then solves it. There are variables on both sides of the equation.

Another debut from two 6th graders, Kermit and Freckles (not their real names).  Watch these two simplify a problem using the order of operations (also known as PEMDAS and GEMDAS).

“Kermit” did 100% of the editing and this was her first time ever using Camtasia Studio!

7th grader, “Rachel”, makes her debut showing us how to solve a multi-step equation.

A new school year and “Swifty” & “Patrick” make their debut video here on Evaluating Algebraic Expressions!
