QuickDiff is an interesting tool that analyses differences in two very similar texts. It was actually developed for examining programming code, but could be a really useful tool to use with students to get them to look more closely at the texts they write and notice the mistakes and corrections and differences in the text.

The National Council of Teachers of Mathematics is a public voice of mathematics education, providing vision, leadership, and professional development to support teachers in ensuring mathematics learning of the highest quality for all students. With 100,000 members and 250 affiliates, NCTM is the world's largest organization dedicated to improving math education in preK‑12. The Greek mathematician Archimedes approximated pi by inscribing and circumscribing polygons about a circle and calculating their perimeters. Similarly, the value of pi can be approximated by calculating the areas of inscribed and circumscribed polygons. This activity allows for the investigation and comparison of both methods. Instructions:   In this applet, polygons are inscribed and circumscribed around circles. The area of the polygons around a circle of radius 1 are calculated on the left, and the perimeter of the polygons around a circle of diameter 1 are calculated on the right. Change the value of n to increase or decrease the number of sides in the polygons, and notice how the calculations of the areas and perimeters begin to approximate pi.

Have you noticed that some of the most "POPULAR" language programs and methods are suddenly getting on board the 21st century train and offering live online learning? Learning a language online in the comfort of your own home with the assistance of a teacher is a truly genius concept. The only problem is, developing a curriculum, finding great teachers and integrating a fully functional eLearning program with progressive technological tools doesn't happen overnight.
