Building Buildings
Learners work together with a partnet to design a building. Using materials, they create the inside and outside of the structure along with works of art. They present their creation to the class and receive constructive criticism in return.
Curated OER
Angle Pairs
High schoolers practice identifying right, vertical, and adjacent angles using a Smartboard. They then determine measurements of all of the angles when only one measurement is given.
Curated OER
Symmetry: Theory, Reality and Art!
Young scholars explore the concept of geometric symmetry. In this geometric symmetry activity, students walk around their school and take pictures of objects that demonstrate symmetry. Young scholars use Microsoft Paint to draw the lines...
