I have started using a new word work activity - called "SuperSpeed 1000" in my classroom. I actually like it so much, that I've started sending it home as homework as well!
What SuperSpeed 100 and 1000 have in common is that it is a game that helps students practice the most frequently read words. Unfortunately, most of these words can not be sounded out. That's the bad news. The good news, though, is that the 100 most common words make up 50% of everything we read!
So . . . if we can just get our students to read those 100 words fluently, we are half way there to fluent readers. The game is very simple and is rigged so each child is constantly breaking records while improving their reading speed. They love to play the game. I love it that their reading is improving.
