This advanced unit is the first in a series of 6 Project M2 units. The units foster inquiry and engage students in critical thinking, problem solving, and mathematical discourse. In this unit, grade 2 units explore properties of twp- and three-dimensional shapes with a focus on the relationship between the two. The focus is on students thinking and acting like mathematicians as they discuss and write about the mathemtics they are learning. Research results show significant achievement gains in geometry from pre to post testing and a significant difference favoring the intervention group over the comparison group with an effect size of 0.84.
