Put a Scientific Calculator on Your Classroom Blog

Web2.0calc is a free online scientific calculator. While it won't replace the most expensive scientific calcualtors, it can do what your average high school student needs it to do. The best part is, you don't have to use it on the Web2.0calc site because they offer three widgets that you can use to embed the calculator into your own blog or website.

Applications for Education
One of the problems the mathematics department in my school faces every year is "disappearing" scientific calculators. Web2.0calc could solve that problem by being placed into teachers' websites where students can use them anytime they like without having to sign-out a calculator for use outside of the classroom.

Encalc - A Free Scientific Calculator

Encalc is a free online scientific calculator that I initially tried more than four years ago. I revisited it this evening and discovered that some more features have been added to it. The two biggest enhancements to note are the addition of a graphing function and the addition of embed codes that you can use to put the calculator on your website. Try Encalc as embedded below.


Applications for Education
Scientific calculators don't come cheap. Some schools have the students buy them other schools provide them and sign them out just like a textbook. Either way someone is absorbing a large cost. Fortunately, for schools and students facing budget crunches, there are web tools like Encalc available for free.

Calkoo - An Excellent Set of Online Calculators

There are a lot of calculators online for performing all kinds of functions from simple addition to solving complex equations. Calkoo is a website that offers forty-three free online calculators for a variety of functions. The list of calculators that Calkoo is divided into ten categories. Those categories are mathematics, measurement & conversion, saving & investing, capital budgeting, cost of capital, wages & taxes, financial analysis, health, loan & leasing, and stock analysis.

Applications for Education
One of my favorite activities in middle school and high school was the stock market simulation activities that two of my teachers had us do. Calkoo offers a good set of calculators that could be used for stock market simulation activities. Of course, if you just need some basic online calculators for your students to use Calkoo puts a bunch of good ones in one place for you.

Here are five free scientific calculators you might also want to try.

A Free Scientific Calculator for Your Website

Web2.0calc is a free online scientific calculator. While it won't replace the TI-84 Plus, it can do what your average high school student needs it to do. The best part is, you don't have to use it on the Web2.0calc site because they offer three widgets that you can use to embed the calculator into your own blog or website. You can see one of those widgets in action below (if you're reading this in RSS you might need to click through to see the widget).

Speed Crunch - A Free Scientific Calculator

Speed Crunch is a free scientific calculator application for Windows, Mac, and Linux operating systems. I learned about Speed Crunch a couple of weeks ago from guest blogger Kim Caise. Kim did a great review of Speed Crunch. Today was the first time I was able to install it and try it. 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.

My math teaching colleague said that Speed Crunch would be very handy for a Trigonometry or Pre-Calculus class. He liked the having ability to store the solution to a prior problem for use in a subsequent equation. Speed Crunch performs all of the functions necessary for high school Algebra and Geometry courses except graphing. In addition to performing all of these functions, Speed Crunch has a "math book" containing commonly used equations and formulas. One Speed Crunch feature that appealed to me from a design standpoint is the color coding of equations to differentiate between constants and variables.















Applications for Education
Speed Crunch is a good free alternative to buying expensive scientific calculators. If you're in a one-to-one environment, Speed Crunch could be a good program to install on student computers.

Free Scientific Calculator

Encalc is a free online scientific calculator. I'm not much of a mathematician so I'll share with you how Encalc describes itself on its homepage. "Encalc is an online scientific calculator. Its strength lies in its ability handle units and dimensional analysis, to define variables and its large database of constants. Parenthesis and scientific formulas are also supported."

One of the features that I really like about Encalc are the explanations of how different variables and constants function within an equation or formula. Click on the image below for an example of the explanations offered for this sample problem.
















Applications for Education
Good scientific calculators are expensive. Some schools have the students buy them other schools provide them and sign them out just like a textbook. Either way someone is absorbing a large cost. Fortunately for schools and students facing budget crunches, there are web tools like Encalc available for free.
