The other way we practice is through games. Sometimes, its just games, sometimes its in a station format. With my larger classes, they stay in their seats and the stations rotate. In my smaller classes, they can move around. It's about crowd control sometimes.
I teach a Math lab and it is completely designed in a station rotation format. Students complete four stations a week and stations are all game formatted. This is their second math class of the day. These students failed the state test and this gives them an extra class to help them with their math skills.
So, how do you practice?
