I sent this link to Chris Harrow, a colleague who teaches math at The Westminster School in Atlanta. Here are his first impressions:
Cool = very smooth functionality on the iPad, you can do all the explorations in the most excellent iPad touchscreen environment, a very tactile approach to learning geometry.
Frustrating = you have to create the docs elsewhere, on first exploration, I don't see a way to do constructions directly in this app. If a kid gets a good idea that requires additional "stuff" on the construction, s/he may not be able to instantly follow up on intuition.
Any one else want to weigh in?
3DTOAD.com is a library of 3D images that you can rotate and explore. It includes skulls, skeletons, dissections, coral, geology, and even music. These could be great visuals on an Interactive White Board or used on an iPad.
Created by the people who made Vimeo, DIY is an open tool for kids to make their own digital portfolios and for parents to have a login to the account. Using the app and the web, kids can save all that they create. This is definitely worth exploring when thinking about extended learning environments.
Designed for 1st-2nd grade students, Murky Reef combines reading and math skills in the context of exploring a coral reef. This is the free version, though there is a more robust version available for $3.99. Students can review numbers, sight words, and vocabulary. There is some reporting built in.
Many apps can share/copy to WebDAV. In fact, we have explored options of using Otixo as a cloud-based webDAV server. This free app seems to connect to an internally hosted WebDAV server for uploading/sharing files.
