### One month leave ends on June 22nd

You are probably wondering why I stopped updating this blog for a month. Well, I am quite busy, so I thought I needed a month off. We have a new curriculum here in the Philippines,  so our institute is working on the new teaching guides and learning packages.  This takes most of my time at work, and for the past month, I am bringing some of my work home.

In addition, I am also growing The Mathematical Palette, my new blog. The blog is not about the 'academics' of mathematics but highlights the 'math is fun' mantra.  Most of my posts there are about the appreciation of the beauty and wonders of mathematics.

Of course, you have probably seen Mathematics and Multimedia, my most active blog. I post  articles there everyday which is also one of the reasons why I have not updated this blog lately.

With all that said, vacation is over. I will resume GeoGebra applet blogging this weekend.

By the way, you are all invited to post your applets here. If you are interested to be a contributor to this blog, you can reach me at
