Welcome to another edition of Week in Review. Looks like another busy week is ahead. I will be in Baguio for a 3-day training, so I am not sure if I’ll have the time to write there.

For a little bit of promotion, Baguio is the summer capital of the Philippines. The temperature there is relatively lower (15˚C to 26˚C, but can drop down to 7˚ C) compared to Metro Manila (23˚C-37˚C). It’s a great place to go if you want to escape summer heat.

Anyway, before my Baguio escapade, here are the list of post for this week.

- GeoGebra Tutorial 33 – Lunes and Layers
- New Archive Page, Language Translation, and more
- Divisibility by 7 and Its Proof
- GeoGebra 4.0 Tutorials
- 3d Math Applets Galore at Maths.net
- Divisibility by 8

**My Other Blogs**

That’s all for this week. Have a happy weekend everyone.

In addition, we are also working on a book on College Geometry with GeoGebra (the title has not been finalized yet). Hopefully, it will be tried out this school year and will be published late this year or early next year.

We are also planning to have Level 1 and 2 GeoGebra trainings this summer (April-May, no definite date yet). If you are interested, please email me at gip@gmail.com or mathandmultimedia@gmail.com.
