The application lets you write and draw everything you want on the board, using colored chalks.This application is very useful in many situations: teach your child math, explain graphs to your colleagues, or simply play tic-tac-toe. Let your children play with Blackboard and teach them how to draw their first butterfly. Thank you for taking the time to report any bugs or to request an enhancement to Blackboard application.
