Our county is pushing GUIDE math by Donna Boucher-

I have always done math workshop, but this is slightly different than I have ever done it, but I'm liking it, and so are the kids. I used to have kids go to 3-4 different centers a day, and they never really completed the activities because it was so short. This is different. Students stay at the same center THE ENTIRE math block. Obviously they have more than one activity- they get a list of "must dos" and then "can dos" for when they finish.

G- Games

U- understanding

I- independent

D- developing fluency

E- expressing mathematical ideas

My groups are heterogeneous. Notice- I am NOT a station. This allows me to pull whoever I want, whenever I want. And since they're on the same station the whole time, they don't complain about missing a center the way that they used to (ie. computers, haha).

So when I go to pull groups, I pull up the MAPS learning continuum and start with the lowest for that skill. I pull 4-6 and work on a skill. This is normally my longest group I meet with. I often don't meet with the highest group until several days into the unit, because they don't need the basic review. I've also worked really hard on self monitoring- my students know that they need to advocate for themselves... if they're struggling with a topic, they can always join my group for extra support. They know I'm also ok with them excusing themselves if they can prove they know it.

That was probably way more long winded than you expected :P haha! If you're interested in more info, let me know- I shared photos and explained how I set up with a bunch of teachers at other schools earlier this year. This was a total game changer for me, and my scores are reflecting it!
