![]() Parentheses can be used as well numbers with a maximum of 50 decimal places. You type in any expression that you want to solve you can use an unlimited number of variables. It is much easier to use than the basic calculator in Windows Accessories or on a Mac. I recently came across the " Speed Crunch Calculator" that wo uld be great for use in a 1-to-1 environment or class demonstration of solving math equations. So enough about me and my crew, on with the show! Speed Crunch Calculator Peggy George, author of " My Web 2.0 Adventures", and Lorna Costantini, author of " Classroom Blogging" and co-host of "Parents as Partners" on EdTechTalk. I am so honored to be a part of this project with Steve Hargadon, founder of Classroom 2.0 and Future of Education, Dr. Each broadcast we feature a newbie question and an ed tech topic pertaining to technology used in the classroom and is geared for tech users of all levels from newbies to experts. I write my own blog, " Kim's Ventures in Educational Technology" about educational technology issues and tech tools as well as co-host a weekly broadcast on Saturdays through Classroom 2.0 called "Classroom 2.0 LIVE!". Currently I am semi-retired as I am not working on a campus but am doing several things online. In 2006, I achieved national board certification in Career and Technology with a specialty in Technology Education. My name is Kim Caise and I have been an educator and instructional technologist for the past 20 years. Hello and thank you for reading my guest blogger post! Let me introduce myself to you with a brief bio. If you're in a one-to-one environment, Speed Crunch could be a good program to install on student computers. Speed Crunch is a good free alternative to buying expensive scientific calculators. One Speed Crunch feature that appealed to me from a design standpoint is the color coding of equations to differentiate between constants and variables. In addition to performing all of these functions, Speed Crunch has a "math book" containing commonly used equations and formulas. Speed Crunch performs all of the functions necessary for high school Algebra and Geometry courses except graphing. He liked the having ability to store the solution to a prior problem for use in a subsequent equation. My math teaching colleague said that Speed Crunch would be very handy for a Trigonometry or Pre-Calculus class. I'm not a math teacher by any stretch of the imagination so I had one of my math teaching colleagues also try Speed Crunch after I installed it on my computer. Today was the first time I was able to install it and try it. I learned about Speed Crunch a couple of weeks ago from guest blogger Kim Caise. ![]() Speed Crunch is a free scientific calculator application for Windows, Mac, and Linux operating systems.
