A very engaging set of rotations for perimeter.
Hands on activities with 2 iPad applications that can be used to aid student learning.
MAB Blocks, Trundle wheels and Geoboards would be needed to complete these activities.
My kids shared iPads, 1 between 2 when doing this rotations.
A set of 'boring questions' is at the end for students who would rather sit and learn by rote, rather than participating with their group.
