1 Warm Up - 10 minutes

Each day, students complete a warm-up that usually consists of spiraling the previous day's material, in addition to older material.  Warm-up problems also sometimes extend lessons that students have encountered before to more unfamiliar contexts.

2 Play of the Day - 40 minutes
Grouping students to maximize peer tutoring and collaboration
Classroom Setup

I usually group students according to the following:

- the front row (6 seats) are reserved for kids who are best served by working with me.  These are generally the middle low kids - not necessarily the lowest kids.

- the most struggling students are seated next to a strong tutor, as they require more than small-group attention, they need 1-on-1 tutoring as the lesson goes by.

- most middle students are seated next to a a strong-middle student, to maximize the quality of their discussion.

I think about the entire seating chart in pairs.


This configuration works really well with a mixed review lesson like today's.  I work with the front row while the rest of the class works independently or collaboratively.

3 Huddle - 10 minutes

For the huddle for this lesson, I take care to spend a lot of time during independent practice uncovering where students still have misconceptions, and then pushing to talk about those in the huddle.  I also take note of where kids did NOT get to practice, and then I spend time reviewing those problems.  The most important part of today's lesson is the data I get from their independent practice.

The power of a mid-unit review

I just think it is SO important, in a long unit with a lot of new content that builds upon itself, to have a mid-unit "pause" day, for kids to consolidate their understanding, review and retain key concepts, and extend and deepen their understanding and fluency.  It allows for a much longer independent practice where you can do student grouping, partner work, small group work, to really hit a lot of things at once.  So I highly recommend doing these days as often as your scope and sequence allows.

4 Homework - 15 minutes

Homework is to be completed at home and should take students approximately 15 minutes.
