The majority of students made sets of tangrams and used them to understand a given unit of area. Some of the discussions were very enlightening. Some students were still cutting out tangrams 20 minutes into the activity.
The first rotation of Specials started today. That's the Rio del Sol version of electives. I have a group learning coding and they were attentive and interested. They seemed to enjoy Ninja Cat from Bootstrap.
A couple of students helped me search for tangrams after school. I don't have any plastic sets.
