I have a 'green' class that has 5th graders that can't read. They've all got learning problems, mostly ADD and dyslexia. They have trouble focusing on phonics videos and worksheets. So I don't even bother with those... Instead we play an alphabet/phonics game for 20 minutes. I say a letter or sound and whoever can write it down first (on a piece of paper, or better yet, on the whiteboard), gets one point.
One day during break time, two of my green students wanted to play the alphabet game. Other students wanted to join in, so I changed the rules so that the higher-level students had to write in cursive.
