Teach algebra geometrically!
Students will DISCOVER the rules for factoring and completing the square rather than memorize blind algorithms. Why lecture when you can facilitate REAL learning?
Enter ANY quadratic expression in standard, vertex, or factored form and get a digital algebra tile model!
The tiles snap in place and don't overlap.
This is perfect for teaching students how to expand, factor and complete the square to transform a quadratic between each algebraic form.
This software requires Windows to run.
It is desktop application, created in VB.net (4.5 framework to be specific).
I created this out of need! The need for better virtual algebra tiles! Students find the physical tiles cumbersome to manipulate, and most of the virtual tiles I've found for interactive whiteboards overlap and do not align perfectly to which frustrates many students!
This is more than a virtual algebra tile modeller... it includes step by step instructions, guiding students to the standard, factored, or vertex form! It recognizes when the tiles have been factored (built into a rectangle) or the square has been competed. More than this, it dynamically knows the answer giving either a green checkmark, a red x, or a yellow "half way checkmark" if their answer is not formatted quite right.
I continue to tweak and update this program, as new ideas and suggestions present themselves from my own experiences with my students, or as bugs are found (or course!) So you can always download a fresh version, should the file change. There is an option to "Just play with the tiles" if you don't wish to be restricted to quadratic expressions. You can add tiles to the panel and it will give the algebraic polynomial tally up top (and even tell you if your tiles are factorable or not).
You can use this on an interactive whiteboard as a teaching tool, or throw the file in a network drive for students to use individually in a computer lab. You can use this software any time you would have used physical algebra tiles in the past.
Feel free to use this product with your own students, but please do not distribute or post the file openly on the internet or share with colleagues, as this would violate copyright permissions. Send them here! I welcome your feedback and suggestions.
