You've Got Triangles!

Each group needs:

• protractors, one per student
• Triangles Activity Assessment (PDF), two per student (pre/post)
• Triangles Activity Worksheet (PDF), one per student

To share with the class:

• LEGO MINDSTORMS EV3 robot, such as EV3 Core Set (5003400) at https://education.lego.com/en-us/products/lego-mindstorms-education-ev3-core-set/5003400#lego-mindstorms-education-ev3; alternatively, if enough LEGO robot kits are available, provide one for each student group, instead of sharing one kit with the entire class.
• computer with USB cable, to download and transfer ev3 (EV3)file
• painters tape, or other tape suitable to mark a triangle shape on the classroom floor
• a stack of textbooks, to use to line the triangle shape taped on the floor
• a class set of rulers, yardsticks or meter sticks

Note: This activity can also be conducted with the older (and no longer sold) LEGO MINDSTORMS NXT set instead of EV3; see below for those supplies:
