I admit it. I am a geometry nut. It is my favorite subject to teach, which I have been doing for the past 30 years (wow….said that out loud!!). Geometry to me is all about logic and connections and relationships of shapes. It should be hands-on, it should be visual, and with technology, is should be dynamic – meaning you can see and discover relationships through movement and manipulation. There are many good resources out there (for those of you looking for a ‘textbook’, Discovering Geometry has always been my go to – it’s all about learning geometry through hands-on discovery and connections. It’s on it’s 5th edition, and the ebook has dynamic investigation using ClassPad.net (formerly used Geogebra), and ClassPad.net has made huge strides in advancing it’s geometry functionality, which is what this post is focused on. My goal over the next few posts is to focus on specific geometry explorations using some of ClassPad.net’s geometry functionality, but today’s post is an overview of what’s new.
ClassPad.net has all the tools you would expect a geometry software to have – i.e. points, straight-edge tools, polygon tools, display tools, expressions, equations, etc. It has some others don’t have – i.e. tools for conics for example. Below is a list of some of the added features as we continue to improve the functionality of the software (which is FREE, btw!!)
- Compass Tool
- Ability to add in images and use them as part of your geometry explorations
- Ability to create sliders for transformations (dilations, rotations, translations, reflections)
- Trace feature
- Multiple Grids, including isometric
- Ability to lock constructs
- Ability to create a rigid polygon (meaning it won’t change shape once constructed)
- Ability to add tick marks to sides and angles
- Ability to change the style of points – i.e. dot, square, x
- Ability to measure exterior angles explicitly and create angles 0-360
- Ability to construct a specific regular polygon (n-gon) by constructing one side and choosing n (number of sides)
- Ability to duplicate constructs without have to ‘reconstruct’ them.
I will be creating videos on each of these features and how to use them for future postings, but today, I wanted to show you where you can find the different new features. Be sure to visit ClassPad.net and sign up for an account (so you can save any work you do). Both the Free and Basic accounts are completely free and have everything you could need for a classroom (don’t forget there is calculations, graphing, statistics, financial tools, and text as well as geometry!). Below is a quick how-to on finding where all the new features for geometry are – stay tuned for future how-to’s on using the specific features. Meanwhile, why not try and explore things on your own? Have fun!!
