Scratch Pen Tools and Geometry
Geometry Project Helpful Code and Steps
Geometry Rubric
Overall Objectives:
- To gain a better understanding of geometry: including angles, geometric figures and some geometric terms (polygon, quadrilateral, equilateral, equiangular, closed, open, regular, supplementary angles, internal angles, external angles.)
- To experiment with math in a fun way.
- To add more programming skills to your Scratch tool kit.
