N.M. --- It's great that students get time to "play" with the relational rods in order to become comfortable and understand the value of each rod.

# data[].attributes.body
N.M. --- The use of virtual manipulatives (relational rods) are very engaging for students. I love that they had a chance to explore this tool on the SmartBoard

N.M. --- using snap-cubes for area requires student to use spatial reasoning to distinguish between the 2 dimensional aspects of area and the 3 dimensional aspects of the cubes.

N.M. --- Geoboards help students build spatial sense because they have to visualize the square units.

N.M. --- Using the "Frameworks" is a great idea for area -  this is a great tool to help students "visualize" and "spatialize" area.

N.M. -- Wow! Students using the Relational Rods to show area???!!! Were they able to identify the value of each rod quickly? So exciting!
