Today students learned about quadrilaterals:

Our lesson began with students making a variety of shapes using geoboards and elastics. After the students were finished making their shapes, I sorted the geoboards into 2 piles. Students had to figure out what my sorting rule was (one pile had shapes with 4 sides and angles and the other pile didn't).

Afterwards, students were challenged to make a wide variety of quadrilaterals using the iPads (they used an online ipad compatible version of a geoboard). Some students also took screenshots of their geoboards and loaded them into the Educreations app (see images below).
