The more hands-on my students can be the better. I love to get them up out of their seats and working with other students. Games are a great way to review skills or to fill those extra minutes that you have in the day. I always have plenty of games copied and ready to go. Whenever I see a need for a change of pace, I can grab a game out of my drawer, and we are ready to practice our learning.
Use manipulatives as much as possible. Students want to get their hands on things. I use manipulatives in math as often as possible.
