I learned about the magnifying tool on the IPad. You press your finger on a word and it allows you to move the cursor in the word.
IPads don't really like Blogger. Blogger (on the IPad) doesn't show you all of the tools available. This causes a lot of headaches when trying to embed videos or add pictures, etc.
I plan on implementing strict regulations for the use of the devices in my room. The expectations will be well known. Students who do not follow the expectations will no longer have access to the devices.
