From time to time I think my students just need a “glue” day. We’ve learned and practiced a bunch of related skills, but maybe they’ve been somewhat out of context, or they’ve been rushed, or they’ve had a week off of class (ahem Regents), or the learning has been too straightforward. They (and I) appreciate a day to just practice and work together. This happens a lot in our classes, it’s a time for them to bunch together odd learning stuffs into one mass.
Encourage them to work in groups, work how they are comfortable, and I provided a key to the cross-number puzzle that they were working on up front. I walked and answered questions for 40 minutes for each of the 4 sections.
