One thing I was finding in class was that I was trying to use online resources more often in day to day lessons, things like Letters and Sounds games during phonics or Maths Games online for mental oral, but the problem was that only one child could use the whiteboard at a time.
One fantastic thing about Android tablets is the ability to handle flash content, which the majority of these online games are. Now when I find an online resource that I would like to use in a lesson I can simple "push" the link to the tablets and the children can interact with it themselves. This works really well as an extension activity based around our class session work. If a child finishes their work and I am happy with the quality they can then access the online resource at their tables.
