A Block Graphic Calculator

Calculators have come a long way since the first ones that could add, subtract, multiply, and divide.  Now, for a modest cost, it’s possible to purchase a graphing calculator.  Or, with your computer, you can put a free one in your browser.  i.e. Desmos Graphing Calculator

But there’s another interesting option.

Many classrooms are introducing students to programming using any one of a variety of block programming languages.  It seems to me that a natural progression would be a block graphing calculator.  And, there is one at the Blockly site.

Choose from a toolbox that includes:

Math

Variables

and Logic

If your students are familiar with a block programming language, the technique is similar.  Just drag the components out to the workplace, lock them together, add any necessary parameters, and you’re done.

Results are immediately displayed in the graphing window.  Move your cursor over any part of your graph to display the x and y co-ordinates.

The interface is clear and easy to navigate.  I think this is a definite keeper.  It’s positioned as a nice transition between block programming and a full-blown graphic calculator with all of its distracting bells and whistles.
