Investigation 1: Motions with Tetrominoes • Measuring an area by covering a flat space with squareunits • Finding systematically all possible geometric arrangements of a given number • Finding patterns for covering a space • Comparing area of rectangles with different dimensions • Describing physical motions in precise ways as a seriesof slides, flips and turns • Comparing two shapes to decide if they are congruentor not after using geometric motions - slides, flips, turns
to try fitting one shape exactly on top of the other
