PhET is a free useful resource that I have been recommending for a few years. It now affords greater than 100 math, physics, chemistry, and biology simulations that you should use in your classroom free of charge. About two years in the past PhET began creating new simulation and enhancing present ones so as to add accessibility options. Final week PhET launched the newest simulation to incorporate accessibility options. Now there are actually 46 PhET simulations that embrace accessibility options.  

Quadrilaterals is the newest PhET simulation. With this simulation college students can transfer the perimeters of quadrilaterals to see how that results the form. The simulation can be utilized in classes about classifying quadrilaterals. 

Like virtually all PhET simulations this new one can be utilized on-line and offline. You may share it in Google Classroom or in your favourite LMS. The simulation will be embedded into an internet web page as I’ve carried out beneath.
