In late March I discovered the Mathematics and Multimedia blog and shared it here on April 1. Mathematics and Multimedia impressed me with its depth of tutorials for teaching mathematics with Google Sketchup and GeoGebra. Now the author of Mathematics and Multimedia, Guillermo Bautista, is organizing a mathematics blog carnival. Topics to addressed in blog carnival submissions include integration of technology in teaching mathematics, connections among different topics and mathematics as well as connections of mathematics to other fields, and pedagogy and teaching mathematics.
