Kids love the little dry erase lap boards, but I don't. The markers stink, they invariably run out of ink or squeak right when even the wiggliest kids are on task. Kindergartners draw on their clothes, skin, the carpet, or worst of all- the one child whose parent sends their child to school in Sunday best. Work gets wiped off, or they run out of room, and just when a child has done AMAZING work it is erased. And the hassle of storing and passing out the markers Nd erasers and boards too- what a pain.
Doodle buddy is another great option too. It has LOTS of choices in color, writing tools, text, special effects, etc. Too many really, to replace the simple whiteboard, but perfect for creative expression, what I like to call Digital Ink. My students make homepage and lock screen pictures using Doodlebuddy. Today I used its' tic-tac-toe backdrop to have kids practice writing sight words and letters we are working on.
I like to have them use my homemade stylus for writing on the iPads.
