This is a great project I used with my third graders in which students design their own robot while applying their knowledge of the following vocabulary terms- point, line, endpoint, line segment, right angle, acute angle, obtuse angle, perpendicular lines, and parallel lines.
A checklist for students with the vocabulary words and definitions is included along with a rubric, in addition to a framed piece of paper students can use to draw their projects, as well as an early finisher extension.
